Full textC'est à la gestion de ce phénomène, le conflit, que nous nous sommes intéressés dans le travail présenté dans ce mémoire, et plus particulièrement à la gestion de conflits par négociation. Nous proposons l'approche DEPNET (product Data dEPendencies NETwork identification and qualification) pour supporter au processus de gestion de conflits basée sur la gestion des dépendances entre les données. Ces données échangées et partagées entre les différents intervenants sont l'essence même de l'activité de conception et jouent un rôle primordial dans l'avancement du processus de conception.
Cette approche propose des éléments méthodologiques pour : (1) identifier l'équipe de négociation qui sera responsable de la résolution de conflit, et (2) gérer les impacts de la solution retenu suite à la résolution du conflit. Une mise en œuvre des apports de ce travail de recherche est présentée au travers du prototype logiciel DEPNET. Nous validons celui-ci sur un cas d'étude industriel issu de la conception d'un turbocompresseur.

Full textNetwork inference has more and more applications, particularly in human health and environment, for the study of micro-biological and genomic data. Networks are indeed an appropriate tool to represent, or even study, relationships between entities. Many mathematical estimation techniques have been developed, particularly in the context of Gaussian graphical models, but also in the case of binary or mixed data. The processing of abundance data (of microorganisms such as bacteria for example) is particular for two reasons: on the one hand they do not directly reflect reality because a sequencing process takes place to duplicate species and this process brings variability, on the other hand a species may be absent in some samples. We are then in the context of zero-inflated data. Many graph inference methods exist for Gaussian, binary and mixed data, but zero-inflated models are rarely studied, although they reflect the structure of many data sets in a relevant way. The objective of this thesis is to infer networks for zero-inflated models. In this thesis, we will restrict to conditional dependency graphs. The work presented in this thesis is divided into two main parts. The first one concerns graph inference methods based on the estimation of neighbourhoods by a procedure combining ordinal regression models and variable selection methods. The second one focuses on graph inference in a model where the variables are Gaussian zero-inflated by double truncation (right and left)

Full textArtificial neural networks constitute good tools for certain types of computational modelling (being potentially efficient, easy to adapt and fast). However, they are often considered difficult to interpret, and are sometimes treated as black boxes. However, whilst this complexity implies that it is difficult to understand the internal organization that develops through learning, it usually encapsulates one of the key factors for obtaining good results. First, to yield a better understanding of how artificial neural networks behave and to validate their use as knowledge discovery tools, we have examined various theoretical works in order to demonstrate the common principles underlying both certain classical artificial neural network, and statistical methods for regression and data analysis. Second, in light of these studies, we have explained the specificities of some more complex artificial neural networks, such as dynamical and modular networks, in order to exploit their respective advantages in constructing a revised model for knowledge extraction, adjusted to the complexity of the phenomena we want to model. The artificial neural networks we have combined (and the subsequent model we developed) can, starting from task data, enhance the understanding of the phenomena modelled through analysing and organising the information for the task. We demonstrate this in a practical prediction task for telecommunication, where the general domain knowledge alone is insufficient to model the phenomena satisfactorily. This leads us to conclude that the possibility for practical application of out work is broad, and that our methods can combine with those already existing in the data mining and the cognitive sciences

Full textThe second decade of the current millennium can be summarized in one short phrase: the advent of data. There has been a surge in the number of data sources: from audio-video streaming, social networks and the Internet of Things, to smartwatches, industrial equipment and personal vehicles, just to name a few. More often than not, these sources form networks in order to exchange information. As a direct consequence, the field of Graph Signal Processing has been thriving and evolving. Its aim: process and make sense of all the surrounding data deluge.In this context, the main goal of this thesis is developing methods and algorithms capable of using data streams, in a distributed fashion, in order to infer the underlying networks that link these streams. Then, these estimated network topologies can be used with tools developed for Graph Signal Processing in order to process and analyze data supported by graphs. After a brief introduction followed by motivating examples, we first develop and propose an online, distributed and adaptive algorithm for graph topology inference for data streams which are linearly dependent. An analysis of the method ensues, in order to establish relations between performance and the input parameters of the algorithm. We then run a set of experiments in order to validate the analysis, as well as compare its performance with that of another proposed method of the literature.The next contribution is in the shape of an algorithm endowed with the same online, distributed and adaptive capacities, but adapted to inferring links between data that interact non-linearly. As such, we propose a simple yet effective additive model which makes use of the reproducing kernel machinery in order to model said nonlinearities. The results if its analysis are convincing, while experiments ran on biomedical data yield estimated networks which exhibit behavior predicted by medical literature.Finally, a third algorithm proposition is made, which aims to improve the nonlinear model by allowing it to escape the constraints induced by additivity. As such, the newly proposed model is as general as possible, and makes use of a natural and intuitive manner of imposing link sparsity, based on the concept of partial derivatives. We analyze this proposed algorithm as well, in order to establish stability conditions and relations between its parameters and its performance. A set of experiments are ran, showcasing how the general model is able to better capture nonlinear links in the data, while the estimated networks behave coherently with previous estimates

Full textThe functioning of urban area is based on technical services and networks which are always more expanded, complex, dense and sophisticated. These networks, although efficient and robust in their day-to-day management, are vulnerable to major hazards and dependent on one another. Phenomena of cascading failures can then occur within these complex systems, whether at technical or organizationel level. This propagation of system-to-system failures is done through dependencies and leads to the gradual aggravation of the impacts of the initial event and the increase of the impacted area, making recovery processes more difficult and slower. The definition and characterization of these phenomena underline their importance, their complexity, their criticality, and paradoxically the lack of information related to them. These conclusions lead us to consider the interest of their study, whether before or after their occurrence, empirically or through models, in order to help stakeholders identify and predict cascading scenarios, or to consider palliatives solutions and vulnerability reduction actions. The state of the art shows that the study and modelling approaches are very varied, due to the methodologies used but also due to the absence of common definitions and the diversity of contexts. A comparative analysis for selection and application purposes seems to be delicate for a potential leading stakeholder. First, we propose a characterization of these approaches according to parameters that may correspond to the choice criteria. We then propose a more theoretical typology of these approaches, complementary to the characterization of the modeling theories used in the literature. Faced with the challenges posed by the implementation process, we are looking into the question of choosing and developing an appropriate approach for a given context, with the aim of supporting local decision-makers. The aim is to help the leaders to build an approach capable of meeting the needs and objectives of local stakeholders, despite their constraints, to operate with potentially very diverse and imperfect data, to adapt to spatial-temporal resolutions and variable granularities, but also to take advantage of the knowledge acquired by local actors and the tools and resources available. Finally, we propose several standard profiles of approaches, characterized according to the objectives pursued and the context of implementation. An application is then carried out on the Paris metropolitan area, where the risk of major flooding is particularly likely and feared. The aim is to provide elements to improve the consideration and prediction of interdependencies and cascading failures, through an in-depth context analysis, meetings with stakeholders and a survey of network operators. Proposals are made concerning feedbacks analysis and concerning vulnerability mapping currently used. The foreseeable needs for the implementation of a more substantial approach are also identified
