This study is on the subject of music learning tracks for learning a capella music. While there is no specific research on the subject yet it has been known as a phenomenon in the genre of barbershop harmony for as long as the tape recorder has been around, and has grown into a well-established business because of the internet and the possibilities of editing music on home computers. Earlier research in surrounding areas such as choir methodology, ear training and mirror neurons have laid the research ground for the study, and the theoretical perspectives which the data was analyzed through are the sociocultural perspective and variation theory. The purpose of this study is to explore variations in musical results and the pupils experience of learning that can be detected between a group that studies with learning tracks and a group that studies without learning tracks. The two groups were followed learning the same piece of music during four classes through observation and recording of sound. Directly following the last class, the students answered a survey about their experience of the learning process. The results were clear, both from the difference in musical results and from the answers in the survey, learning tracks are better for learning new music than just using sheet music. The results also connect to earlier research in surrounding areas, but even though the results of this study are clear more research is needed in this specific area.

Kurerade musiksamlingar är ett växande område som en direkt följd av den frihet som strömmande musiktjänster som Spotify ger oss. För att kunna kategorisera låtar baserade på subjektiva värderingar på ett skalbart sätt har denna avhandling undersökt om rekommendationer av sådana etiketter är möjliga genom maskininlärning. När 2464 spår med ett eller flera av 22 olika kärnvärden analyserades byggdes en profil för varje spår upp av attribut från tre olika kategorier: redaktionella, kulturella och akustiska. Vid klassificering av spåren undersöktes flera olika metoder för fleretikettsklassificering. Genom att kombinera fem olika transformationsmetoder med tre bas-klassificerare och använda två algoritm-anpassningar konstruerades totalt 17 olika konfigurationer. De olika konfigurationerna utvärderades med flera olika mätvärden, inkluderat (men inte begränsat till) Hamming Loss, Ranking Loss, One error, F1 score, exakt matchning och både träningstid och testningstid. Resultaten visade att transformationsalgoritmen ”Label Powerset” tillsammans med Sekventiell Minimal Optimering utklassade de andra konfigurationerna. Vi fann också lovande resultat för artificiella neuronnät, något som bör undersökas ytterligare i framtiden.

Riviere, Jean-Philippe. "Capturing traces of the dance learning process." Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPASG054.
This thesis focuses on designing interactive tools to understand and support dance learning from videos. Dancers' learning practice represents a rich source of information for researchers interested in designing systems that support motor learning. Indeed, dancers embody a wide range of skills that they reuse during new dance sequences learning. However, these skills are in part the result of embodied implicit knowledge. In this thesis, I argue that we can capture and save traces of dancers' embodied knowledge and use them to design interactive tools that support dance learning. My approach is to study real-life dance learning tasks in individual and collaborative settings. Based on the findings from all the studies, I discuss the challenge of capturing embodied knowledge to support dancers’ learning practice. My thesis highlights that although dancers’ learning processes are diverse, similar strategies emerge to structure their learning process. Finally, I bring and discuss new perspectives to the design of movement-based learning tools

Vi undersöker hur man bäst använder sig av trackermusik för att träna neurala nätverk till att generera polyfonisk musik. Trackermusik kan sägas både vara en speciell instrumental musikgenre och ett speciellt musikformat. Formatet som skiljer sig markant från exempelvis MIDI och MP3 har en del egenskaper som gör det svårare och andra som gör det lättare att träna neurala nätverk med det än med jämförbara musikformat. Därför är det intressant att utforska vilka metoder som är bäst att använda för att utvinna musikinformation ur formatet. Så vitt vi vet har ämnet inte utforskats tidigare och vårt utforskande av det är vår uppsats centrala bidrag till forskningen kring musikgenerering med neurala nätverk. I uppsatsen föreslår vi en metod som konverterar trackermusik till ett sekventiellt format som är lämpligt att använda för att träna neurala nätverk. Vi demonstrerar också att metoden fungerar i praktiken genom att träna ett antal neurala nätverk med en samling på cirka 20 000 instrumentala sånger i trackermusiklagringsformatet MOD som vi sedan utvärderar. Utvärderingen består bland annat i en lyssnarstudie. Resultatet av den visar att den musik som genereras av tre neurala nätverk som vi tränar med trackermusiksamlingen ibland föredras av lyssnare över musik skapad av människor. Vi drar slutsatsen att musikgenererande neurala nätverk kan tränas med hjälp av trackermusik med vår föreslagna konverteringsmetod, men att det är bökigt. På grund av hur trackermusik är uppbyggt och organiserat är det betydligt svårare än vad vi inledningsvis trodde att utvinna musikinformation ur det.

How access to knowledge can be impacted by Information Technology? In the earlier 2000s, communication tools caused a significant turn : media convergence, participative practices and massive data. In this way, free access to knowledge might tend to be democratized. People seem to regain spaces, reversing traditional top-down model, going from producer to consumer, for the benefit of an horizontal model based on collective intelligence. However, it should not automatically be assumed that this leads to a simple model reversing. Collective intelligence is subject to cognitive biases, leading to potential irrational situations. Formerly, those social mechanisms had limited consequences. Nowadays, digital knowledge are massive communicating spaces, giving birth to new access paths and new cleavages. Why this massive and open knowledge, is actually so selective? I propose to explore this paradox. Massive and constant tracking of traces and individuals hyper-connection, these two facts help organizational structures design, where social dynamics are digitalized in a complex way. These structures formalize human trajectories. On this basis, computer scientists set up prediction algorithms and recommender engines. This way, knowledge access is automatized. It can then be asked about people governance, in this context of infrastructure submission: recording traces, designing knowledge structure and automating algorithms

The adoption of new Information and Communication Technologies (ICT) has enabled the modernization of teaching methods in online learning systems such as e-Learning, intelligent tutorial systems (ITS), etc. These systems provide a remote training that which meets the learner needs. A very important aspect to consider in these systems is the early assessment of the learner in terms of knowledge acquisition. In general, three types of assessment and their relationships are needed during the learning process, namely : (i) diagnostic which is performed before learning to estimate the level of students, (ii) formative evaluation which is applied during learning to test the knowledge evolution and (iii) summative evaluation which is considered after learning to evaluate learner’s knowledge acquisition. These methods can be integrated into a semi-automatic, automatic or adapted way in different contexts of formation, for example in the field of languages literary learning such as French, English, etc., hard sciences (mathematics, physics, chemistry, etc.) and programming languages (java, python, sql, etc.). However, the usual evaluation methods are static and are based on linear functions that only take into account the learner’s response. They ignore other parameters of their knowledge model that may disclose other performance indicators. For example, the time to solve a problem, the number of attempts, the quality of the response, etc. These elements are used to detect the profile characteristics, behavior and learning disabilitiesof the learner. These additional parameters are seen in our research as learning traces produced by the learner during a given situation or pedagogical context. In this context, we propose in this thesis a learner evaluation approach based on learning traces that can be exploited in an adaptation system of the resource and/or the pedagogic situation. For the learner assessment, we have proposed three generic evaluation models that take into consideration the temporal trace, number of attempts and their combinations. These models are later used as a base metric for our resource adaptation model and/or learning situation. The adaptation model is also based on the three traces mentioned above and on our evaluation models. Our adaptation model automatically generates adapted paths using a state-transition model. The states represent learning situations that consume resources and the transitions between situations express the necessary conditions to pass from one situation to another. These concepts are implemented in a domain ontology and an algorithm that we have developed. The algorithm ensures two types of adaptation : (i) Adaptation of the situation and (ii) Adaptation of resources within a situation. In order to collect traces of training for the implementation of our approaches of learner evaluation and adaptation of resources and learning situations, we conducted experiments on two groups of students in Computer Science (L2). One group in classical training and the other group in adapted training. Based on the obtained traces from the students’ training sessions, we assessed merners based on our evaluation models. The results are then used to implement the adaptation in a domain ontology. The latter is implemented within oracle 11g which allows a rule-based semantic reasoning. After comparing the results of the adapted training with those obtained from the classical one, we found an improvement in the results in terms of general average and standard deviation of the learner averages

Ji, Min. "Exploiting activity traces and learners’ reports to support self-regulation in project-based learning." Thesis, Lyon, INSA, 2015. http://www.theses.fr/2015ISAL0032/document.
Project-based Learning (PBL) is a learner-oriented instructional method, which enables learners to carry out challenging and authentic projects by thorough investigations. PBL affords learners the opportunities to organize and plan the project, to collaborate with peers and to look for the resources and guidance to achieve the project goals. However, PBL is difficult to implement successfully because learners often lack of the self-regulation skills required to monitor, reflect, manage and assess their project activities and learning. Self-Regulated Learning (SRL) can train learners to gain these skills. However, most learning systems used in PBL focus on providing rich learning materials to the learners but rarely offer possibilities to monitor and analyze their project and learning processes. The main goal of this thesis is to support SRL during PBL situations. We propose a general architecture of Project-based Learning Management System (PBLMS), which help learners to understand how to regulate their learning activities during the projects. This general architecture integrates an existing Learning Management System (LMS) and two tools we propose: a reporting tool and a dynamic dashboard. The reporting tool enhances learners' reflective processes by leading them to describe their non-instrumented activities, their reflections and assessments on the project activities based on semi-structured sentences. The system can record automatically the activity traces of the users' interactions with the LMS, the reporting tool and the dashboard. These activity traces are merged with the self-reporting data so that indicators can be calculated basing on this entire information. The dynamic dashboard supports learners in creating customizable indicators. Learners can specify the data to take into account, the calculation and the visualization modes. We implemented this theoretical proposition with the development of the DDART (Dynamic Dashboard based on Activity and self-Reporting Traces) platform that integrates the reporting tool and the dynamic dashboard. To evaluate the proposition, we firstly test the ability of DDART to recreate a large sample of indicators that are proposed in existing researches about the analysis of activities, cognition, emotion and social network. Furthermore, an experiment was conducted to evaluate the usability and perceived utility of DDART. According to the results of this experiment, we found that DDART supports learners' reflections on the way they carry out the project and provides them with the opportunities to monitor their activities and learning, even if the indicator creation could be difficult for the novices

Nos últimos anos, o rastreador TLD (Tracking-Learning-Detection) se destacou por combinar um método de rastreamento através do movimento aparente e um método de detecção para o problema de rastreamento de objetos em vídeos. O detector identifica o objeto pelas aparências supostamente confirmadas. O rastreador insere novas aparências no modelo do detector estimando o movimento aparente. A integração das duas respostas é realizada através da mesma métrica de similaridade utilizada pelo detector que pode levar a uma decisão enviesada. Neste trabalho, é proposto um framework para métodos baseados em múltiplos rastreadores onde o componente responsável pela integração das respostas é independente dos rastreadores. Este componente é denominado mediador. Seguindo este framework, um novo método é proposto para integrar o rastreador por movimento e o detector do rastreador TLD pela combinação das suas estimativas. Os resultados mostram que, quando a integração é independente das métricas de ambos os rastreadores, a performance é melhorada para objetos com significativas variações de aparência durante o vídeo.
On the problem of tracking objects in videos, a recent and distinguished approach combining tracking and detection methods is the TLD (Tracking-Learning-Detection) framework. The detector identifies the object by its supposedly confirmed appearances. The tracker inserts new appearances into the model using apparent motion. Their outcomes are integrated by using the same similarity metric of the detector which, in our point of view, leads to biased results. In our work, we propose a framework for generic multitracker methods where the component responsible for the integration is independent from the trackers. We call this component as mediator. Using this framework, we propose a new method for integrating the motion tracker and detector from TLD by combining their estimations. Our results show that when the integration is independent of both tracker/detector metrics, the overall tracking is improved for objects with high appearance variations throughout the video.

The relationship between the big five personality traits, Extraversion, Agreeableness Neuroticism, Conscientiousness and Openness to Experience and deep and surface approaches to learning forms the basis of this article. The findings of a research study in this milieu will be presented to prove that earlier studies in this field have been upheld, but that an important deviation has occurred on certain levels of personality. A students way of learning implies the type of learning that is taking place. Ultimately we as lecturers want to encourage deep learning as this stimulates retention of information, important in production of students that are ready for employment.

This thesis is funded by the Rhône-Alpes Region as a part of the project < Personalisation of Technology-Enhanced Learning (TEL) Systems >. Personalising TEL Systems is, above all, dependent on the capacity to produce relevant and exploitable traces of individual or collaborative learning activities. In this field, exploiting interaction traces addresses several problems ranging from its representation in a normalised and intelligible manner to its processing and interpretation in continuous way during the ongoing TEL activities. The proliferation of trace-based exploitations raises the need of generic tools to support their representation and exploitation. The main objective of this thesis is to define the theoretical foundations of such generic tools. To do that, we define the notion of Trace-Based System (TBS) as a kind of Knowledge-based system whose main source of knowledge is a set of trace of user-system interactions. This thesis investigates practical and theoretical issues related to TBS, covering the spectrum from concepts, services and architecture involved by such TBS (conceptual framework) to language design over declarative semantics (formal framework). The central topic of our framework is the development of a high-level trace transformation language supporting deductive rules as an abstraction and reasoning mechanism for traces. The declarative semantics for such language is defined by a (Tarski-style) model theory with accompanying fixpoint theory

Nyligen utförda arbeten har visat att faltningsnätverk framgångsrikt kan hantera tidsserier som indata i olika problem. Observationen utnyttjas i detta examensarbete som introducerar en ny metod som kombinerar tekniker för maskininlärning för att skapa lönsamma handelsstrategier. Metoden löser ett binärt klassificeringsproblem: beroende på en viss tidpunkt, tillgång till priser före denna tidpunkt och ett säljkriterium så är målet att förutsäga nästa prisvariation. Klassificeringsmetoden baseras på faltningsnätverk som kombinerar två stora förbättringar: en speciell form av bagging och en viktpropagering för att förbättra noggrannheten och reducera modellens varians. Det rullande lärandet och faltningsnätverken kan utnyttja tidsberoendet för att förbättra handelsstrategin. Den presenterade arkitekturen klarar av att prestera bättre än experthandlare.

In contrast to rote learning, meaningful learning aims to associate new knowledge with knowledge already acquired. Mind mapping activities require and support the implementation of meaningful learning strategies and enlighten the knowledge structure of the learner. However, teachers who integrate mind mapping into their educational activities have to deal with the final rendering of maps, and risk to misinterpret and wrongly evaluate them due to the lack of information about their construction process. In this thesis, we are interested in a posteriori observation of the engagement of learners along its behavioral and cognitive dimensions, in order to propose processoriented indicators that help to understand actions and construction choices of mind maps. We followed the Design Based Research methodology, that allowed us to propose three levels of contributions : 1) a theoretical model of engagement (behavioral and cognitive) for mind mapping activities, 2) a set of indicators of learner engagement constructed from automatically captured map building traces, and 3) a dashboard called MindMap Monitor presenting various indicators to teachers for class and learners monitoring. The model was obtained from a literature review on theories of engagement, including research in educational psychology. The indicators have been defined by comparing the model with the results of several field studies with teachers. The dashboard implementing the indicators was developed following three iterations. Its interface presents synthetic views allowing the comparison of students in the class, the identification of those in difficulty, and detailed views describing the mind mapping activity for each student. Our dashboard was evaluated with an experiment involving 12 teachers. We compared its use with that of final mind maps associated with videos of their construction process. Results show that our indicators on MindMap Monitor are useful to better identify students in difficulty, shared difficulties, as well as difficulties for individual students. Results concerning the understanding of the mind maps construction process are more balanced. We were also able to identify several ways to improve both the content and the visualizations of the dashboard. The perspectives of our work are mainly related to monitoring learners’ engagement in real time for the intervention and adaptation of the teachers’ educational strategies

Tiivistelmä Tässä väitöskirjassa tutkitaan oppilaiden itsesäätöisen ja strategisen oppimisen ilmenemistä oppimisprosessin aikana. Tutkimuksessa hyödynnetään g/nStudy- oppimisympäristöä, jonka avulla on mahdollista tukea ja jäljittää oppimisen strategista toimintaa. g/nStudy-oppimisympäristö tallentaa lokidataa, joka on tarkkaa ajallista informaatiota siitä toiminnasta, jota oppilas tekee työskentelynsä aikana. Toisin sanoen, lokidatasta on mahdollista jäljittää ne tiedot, jotka reflektoivat strategista – ja itsesäätöistä oppimista. Erityisenä mielenkiinnon kohteena oli selvittää miten lokidatasta voi löytää strategisia oppimisen toimintamalleja, ja miten nämä strategiset oppimisen toimintamallit vaihtelevat oppilaiden, oppilasryhmien ja erilaisten oppimisen tilanteiden aikana. Väitöstutkimus muodostuu kolmesta erillisestä tutkimusaineistosta. Jokaisessa kolmessa aineistossa on hyödynnetty g/nStudy-teknologian mahdollisuuksia tukea ja jäljittää itsesäätöistä oppimista. Tutkimusaineiston analyysissä hyödynnetään mikroanalyyttista lähestymistapaa sekä laadullista tutkimusotetta. Tutkimuksen analyyttinen lähestymistapa antaa mahdollisuuden ymmärtää itsesäätöisen- ja strategisen oppimisen ilmenemistä aidossa oppimistilanteessa. Tutkimustulokset osoittavat, että oppimisympäristöön sisällytettyjä teknologisia työkaluja voidaan käyttää tukemaan itsesäätöistä ja strategista toimintaa. Sen lisäksi samoja työkaluja voidaan käyttää myös menetelmällisenä välineenä tutkittaessa itsesäätöistä – ja strategista toimintaa erilaisissa oppimistilanteissa. Tutkimus -tulokset osoittavat, että oppimisen strategiset toimintamallit vaihtelivat oppilaiden – ja oppimistilanteiden välillä. Oppimisen strategisissa toimintamalleissa oli myös laadullisia eroja sen suhteen, miten usein ne ilmenivät oppimisprosessin aikana ja mistä strategisista toiminnoista ne koostuivat. Johtopäätöksenä voi todeta, että lokidatan käyttäminen tutkimusmenetelmänä edesauttaa paljastamaan opiskelun strategisia toimintamalleja oppilaiden – ja oppilasryhmien välillä. Tutkimuksen perusteella voidaan todeta, että strategiset toimintamallit voivat olla hyvinkin monimuotoisia. On tärkeää tunnistaa, missä tilanteissa ja milloin näitä toimintamalleja käytetään ja erityisesti mikä on niiden vaikutus oppimisen laatuun

This thesis in computer science focuses on the problem of capitalizing analysis processes of elearning traces within the Learning Analytics (LA) community. The aim is to allow these analysis processes to be shared, adapted and reused. Currently, this capitalization is limited by two important factors: the analysis processes are dependent on the analysis tools that implement them - their technical context - and the pedagogical context for which they are conducted. This prevents them from being shared, but also from being simply reused outside their original contexts, even if the new contexts are similar. The objective of this thesis is to provide models and methods for the capitalisation of analysis processes of elearning traces, as well as to assist the various actors involved in the analysis, particularly during the reuse phase. To do this, we answer the following three scientific questions: how to share and combine analysis processes implemented in different analysis tools; how to reuse an existing analysis process to meet another analysis need; how to assist the different actors in the development and exploitation of analysis processes; and how to support them in the development and exploitation of analysis processes. Our first contribution, resulting from a synthesis of the state of the art, is the formalization of a cycle of elaboration and exploitation of the analysis processes, in order to define the different stages, the different actors and their different roles. This formalization is accompanied by a definition of capitalization and its properties. Our second contribution responds to the first barrier related to the technical dependence of current analysis processes and their sharing. We propose a meta-model that allows to describe the analysis processes independently of the analysis tools. This meta-model formalizes the description of the operations used in the analysis processes, the processes themselves and the traces used, in order to avoid the technical constraints caused by these tools. This formalism, common to the analysis processes, also makes it possible to consider their sharing. It has been implemented and evaluated in one of our prototypes. Our third contribution deals with the second lock on the reuse of analysis processes. We propose an ontological framework for analysis processes, which allows semantic elements to be directly introduced, in a structured way, during the description of analysis processes. This narrative approach thus enriches the previous formalism and makes it possible to satisfy the properties of understanding, adaptation and reuse necessary for capitalisation. This ontological approach was implemented and evaluated in another of our prototypes. Finally, our last contribution responds to the last lock identified and concerns new assistances to actors, in particular a new method of researching analysis processes, based on our previous proposals. We use the ontological framework of the narrative approach to define inference rules and heuristics to reason about the analysis processes as a whole (e.g. steps, configurations) during the research. We also use the semantic network underlying this ontological modeling to strengthen assistance to actors by providing them with inspection and understanding tools during the research. This assistance was implemented in one of our prototypes, and empirically evaluated
Saada, Hajer. "Exploiting Model Transformation Examples for Easy Model Transformation Handling (Learning and Recovery)." Thesis, Montpellier 2, 2013. http://www.theses.fr/2013MON20223/document.
Model Driven Engineering (MDE) considers models as first class artifacts. Each model conforms to another model, called its metamodel which defines its abstract syntax and its semantics.Various kinds of models are handled successively in an MDE development cycle. They are manipulated using, among others, programs called model transformations. A transformation takes as input a model in a source language and produces a model in a target language. The developers of a transformation must have a strong knowledge about the source and target metamodels which are involved and about the model transformation language. This makes the writing of the model transformation difficult.In this thesis, we address the problem of assisting the writing of a model transformation and more generally of understanding how a transformation operates.We adhere to the Model Transformation By example (MTBE) approach, which proposes to create a model transformation using examples of transformation. MTBE allows us to use the concrete syntaxes defined for the metamodels. Hence, the developers do not need in-depth knowledge about the metamodels. In this context, our thesis proposes two contributions.As a first contribution, we define a method to generate operational transformation rules from transformation examples. We extend a previous approach which uses Relational Concept Analysis as a learning technique for obtaining transformation patterns from 1-1 mapping between models. We develop a technique for extracting relevant transformation rules from these transformation patterns and we use JESS language and engine to make the rules executable. We also study how we better learn transformation rules from examples, using transformation examples separately or by gathering all the examples.The second contribution consists in recovering transformation traces from transformation examples. This trace recovery is useful for several purposes as locating bugs during the execution of transformation programs, or checking the coverage of all input models by a transformation. In our context, we expect also that this trace will provide data for a future model transformation learning technique. We first address the trace recovery problem with examples coming from a transformation program. We propose an approach, based on a multi-objective meta-heuristic, to generate the textit{many-to-many} mapping between model constructs which correspond to a trace. The fitness functions rely on the lexical and structure similarity between the constructs. We also refine the approach to apply it to the more general problem of model matching

Automatisk musikrekommendation med hjälp av maskininlärning har utforskats av både industrin och akademin genom åren, där två huvudsakliga metoder utkristalliserats: collaborative filtering samt content-based filtering. I det här arbetet har en content-based modell tagits fram, uppdelad i två stadier: Steg 1 som genererar kandidater som Steg 2 sedan ordnade om med hjälp av ett neuralt nätverk som jämförde 5 låtar i taget från en spellista med motsvarande kandidater genererade av Steg 1 En av svårigheterna med att skapa automatiska rekommendationer är utvärderingen av den. I det här arbetet har både en kvantitativ och kvalitativ studie utförts för att försäkra att resultaten motsvarar den faktiska kvaliten hos rekommendationerna. Slutmålet med att hjälpa företag med musikrekommendation ställer också unika problem att lösa i jämförelse med en tjänst för privatpersoner, framförallt relaterat till storleken på de returnerade rekommendationerna. Resultaten visade att Steg 2 lyckades rangordna rekommendationerna från Steg 1 på ett sätt som gav högre poäng i både den kvantitativa och kvalitativa utvärderingen av systemen. De slutgiltiga resultaten var inte helt tillfredsställande, och potentialla orsaker till detta diskuteras. Dessa inkluderar Steg 1 (som inte modifierades inom ramen för detta arbete). Utvärderingen visade dock att de kvantitativa utvärderingsramarna verkar motsvara den upplevda kvaliten hos rekommendationerna baserat på den kvalitativa utvärderingen.

Perceptual-gestural knowledge is multimodal : they combine theoretical and perceptual and gestural knowledge. It is difficult to capture in Intelligent Tutoring Systems. In fact, its capture in such systems involves the use of multiple devices or sensors covering all the modalities of underlying interactions. The "traces" of these interactions -also referred to as "activity traces"- are the raw material for the production of key tutoring services that consider their multimodal nature. Methods for "learning analytics" and production of "tutoring services" that favor one or another facet over others, are incomplete. However, the use of diverse devices generates heterogeneous activity traces. Those latter are hard to model and treat.My doctoral project addresses the challenge related to the production of tutoring services that are congruent to this type of knowledge. I am specifically interested to this type of knowledge in the context of "ill-defined domains". My research case study is the Intelligent Tutoring System TELEOS, a simulation platform dedicated to percutaneous orthopedic surgery.The contributions of this thesis are threefold : (1) the formalization of perceptual-gestural interactions sequences; (2) the implementation of tools capable of reifying the proposed conceptual model; (3) the conception and implementation of algorithmic tools fostering the analysis of these sequences from a didactic point of view

A quantitative research study was conducted in order to gain insight and knowledge into the various destinations CPUT Marketing graduates end up after completing their course of study. A cohort of students that graduated between 2001-2010 was used in this research. The motivation for the study stemmed from the researcher’s experience working at CPUT, lecturing and the researcher’s interaction with the students. The ultimate objective of the study was to trace the graduates, identify their employment status and observe if they are employed in the area for which they have studied.The literature study covers areas that relate to how students choose what to study, graduate skills, the workforce and graduate employment and unemployment. These areas were reviewed from different sources and authors that specialize in graduate development.The researcher elected to work with CPUT graduates as the researcher too is an alumnus of CPUT and was familiar with the policies and procedures of the institution.Results of the research confirmed that tracer studies are an essential tool for tracking graduates and the findings of tracer studies are beneficial for future curriculum development. Although tracer studies yield valuable insight into graduate trajectories they undervalued and underutilized. Furthermore, the results confirm that graduates are employed in the sectors for which they studied or associated sectors. Moreover co-operative education should be further explored to yield better results and perhaps secure employment for the student after graduation.The recommendation is that academic staff revisits the curriculum and better incorporate scarce skills such as critical thinking skills and also institute a formal tracking system that can be used to benefit the department.

Galan, Roberto Fernandez. "Odor coding and memory traces in the antennal lobe of honeybee." Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2003. http://dx.doi.org/10.18452/14997.
Two major novel results are reported in this work. The first concerns olfactory coding and the second concerns sensory memory. Both phenomena are investigated in the brain of the honeybee as a model system. Considering olfactory coding I demonstrate that the neural dynamics in the antennal lobe describe odor-specific trajectories during stimulation that converge to odor-specific attractors. The time interval to reach these attractors is, regardless of odor identity and concentration, approximately 800 ms. I show that support-vector machines and, in particular perceptrons provide a realistic and biological model of the interaction between the antennal lobe (coding network) and the mushroom body (decoding network). This model can also account for reaction-times of about 300 ms and for concentration invariance of odor perception. Regarding sensory memory I show that a single stimulation without reward induces changes of pairwise correlation between glomeruli in a Hebbian-like manner. I demonstrate that those changes of correlation suffice to retrieve the last stimulus presented in 2/3 of the bees studied. Succesful retrieval decays to 1/3 of the bees within the second minute after stimulation. In addition, a principal-component analysis of the spontaneous activity reveals that the dominant pattern of the network during the spontaneous activity after, but not before stimulation, reproduces the odor-induced activity pattern in 2/3 of the bees studied. One can therefore consider the odor-induced (changes of) correlation as traces of a short-term memory or as Hebbian reverberations.

Denna studie undersöker lämpligheten hos Tobii ABs X2-30 eye-tracker för att mäta en students vakenhet. För att avgöra lämpligheten så har tester gjorts i två olika miljöer och med två olika försökspersoner. Miljöerna var en föreläsning och ett flertal webinars medan försökspersonerna var de två manliga författarna av denna studie. Resultaten indikerar att X2-30 kan vara användbar när den används under optimala omständigheter, det vill säga webinars, då den kräver så få störande faktorer som möjligt. Dessa faktorer rör utrustningens mätzon och att försökspersonen inte lämnar denna, samt att hårdvaran inte flyttas under mätning. När utrustningen användes under optimala förhållanden så var det möjligt att få precis data rörande pupillens beteende och ganska korrekt data rörande blinkfrekvens vilket gör utrustningen lämplig för mätning av vakenhet under rätt omständigheter.

The consumer electronics market is dominated by embedded systems due to their ever-increasing processing power and the large number of functionnalities they offer.To provide such features, architectures of embedded systems have increased in complexity: they rely on several heterogeneous processing units, and allow concurrent tasks execution.This complexity degrades the programmability of embedded system architectures and makes application execution difficult to understand on such systems.The most used approach for analyzing application execution on embedded systems consists in capturing execution traces (event sequences, such as system call invocations or context switch, generated during application execution).This approach is used in application testing, debugging or profiling.However in some use cases, execution traces generated can be very large, up to several hundreds of gigabytes.For example endurance tests, which are tests consisting in tracing execution of an application on an embedded system during long periods, from several hours to several days.Current tools and methods for analyzing execution traces are not designed to handle such amounts of data.We propose an approach for monitoring an application execution by analyzing traces on the fly in order to reduce the volume of recorded trace.Our approach is based on features of multimedia applications which contribute the most to the success of popular devices such as set-top boxes or smartphones.This approach consists in identifying automatically the suspicious periods of an application execution in order to record only the parts of traces which correspond to these periods.The proposed approach consists of two steps: a learning step which discovers regular behaviors of an application from its execution trace, and an anomaly detection step which identifies behaviors deviating from the regular ones.The many experiments, performed on synthetic and real-life datasets, show that our approach reduces the trace size by an order of magnitude while maintaining a good performance in detecting suspicious behaviors
