Genestier, Guillaume. "Dependently-Typed Termination and Embedding of Extensional Universe-Polymorphic Type Theory using Rewriting." Electronic Thesis or Diss., université Paris-Saclay, 2020. http://www.theses.fr/2020UPASG045.
Full textDedukti is a logical framework in which the user encodes the theory she wantsto use via rewriting rules. To ensure the decidability of typing, the rewriting system must be terminating.After recalling some properties of pure type systems and their extension with rewriting, a termination criterion for higher-order rewriting with dependent types is presented. It is an extension of the dependency pairs to the lambda-pi-calculus modulo rewriting. This result features two main theorems. The first one states that the well-foundedness of the call relation defined from dependency pairs implies the strong normalization of the rewriting system.The second result of this part describes decidable sufficient conditions to use the first one. This decidable version of the termination criterion is implemented in “SizeChange Tool”.The second part of this thesis is dedicated to the use of the logical framework Dedukti to encode a rich type theory. We are interested in a fragment of the logic beyond Agda which includes two widely used features: extension of conversion with the eta rule and universe polymorphism.Once again, this work includes a theoretical part, with correct encodings of both features in the lambda-pi-calculus modulo rewriting, and a prototypical translator from Agda to Dedukti

Full textP. Broussous and S. Stevens studied maps between enlarged Bruhat-Tits buildings to construct types for p-adic unitary groups. They needed maps which respect the Moy-Prasad filtrations. That property is called (CLF), i.e. compatibility with the Lie algebra filtrations. In the first part of this thesis we generalise their results on such maps to the Quaternion-algebra case. Let k0 be a p-adic field of residue characteristic not two. We consider a semisimple k0-rational Lie algebra element beta of a unitary group G:=U(h) defined over k0 with a signed hermitian form h. Let H be the centraliser of beta in G. We prove the existence of an affine H(k0)-equivariant CLF-map j from the enlarged Bruhat-Tits building B^1(H,k0) to B^1(G,k0). As conjectured by Broussous the CLF-property determines j, if none of the factors of H is k0-isomorphic to the isotropic orthogonal group of k0-rank one and all factors are unitary groups. Under the weaker assumption that the affine CLF-map j is only equivariant under the center of H^0(k0) it is uniquely determined up to a translation of B^1(H,k0). The second part is devoted to the decoding of embedding types by the geometry of a CLF-map. Embedding types have been studied by Broussous and M. Grabitz. We consider a division algebra D of finite index with a p-adic center F. The construction of simple types for GLn(D) in the Budhnell-Kutzko framework required an investigation of strata which had to fulfil a rigidity property. Giving a stratum especially means to fix a pair (E,a) consisting of a field extension E|F in Mn(D) and a hereditary order a which is stable under conjugation by E^x, in other words we fix an embedding of E^x into the normalizer of a. Broussous and Grabitz classified these pairs with invariants. We describe and prove a way to decode these invariants using the geometry of a CLF-map.

Full textKontinuerlig integration består automatiserade tester där det finns risk för att några misslyckas vilket kan leda till felaktig programvara. Liknande fel kan uppstå under olika faser av en programvarans livscykel och det är viktigt att identifiera och gruppera olika feltyper för att optimera felsökningsprocessen. Det har bevisats att språkmodeller baserade på transformatorarkitekturen kan uppnå höga resultat i många uppgifter inom språkteknologi, inklusive att mäta semantisk likhet mellan två texter. Detta arbete undersöker om det är möjligt att gruppera och identifiera nya feltyper genom att använda en transformatorbaserad språkmodell för att skapa numeriska vektorer av loggtext, som består av domänspecifika tekniska termer och numerisk data. Klustren jämförs mot redan existerande grupperingar som skapats av ett befintligt system där feltyper identifieras med manuellt skrivna filter. Det här arbetet visar att det går att förbättra vektorrepresenationerna skapade av en språkmodell baserad på transformatorarkitekturen genom att tilläggsträna modellen för en klassificeringsuppgift. Vektorerna grupperas med hjälp av densitetsbaserade och hierarkiska klusteralgoritmer. Resultaten visar att det är möjligt att skapa vektorer av logg-texter med hjälp av en transformatorbaserad språkmodell och få jämförbara resultat som ett befintligt manuellt system, när klustren evaluerades med V-måttet och Adjusted Rand Index.

Full textThis thesis focuses on some Trudinger-Moser type inequalities and their applications to the study of Sobolev embeddings they induce into the Orlicz spaces, and the investigation of nonlinear partial differential equations with exponential growth.The work presented here includes three parts. The first part is devoted to the description of the lack of compactness of the 4D Sobolev embedding into the Orlicz space in the radialframework.The aim of the second part is twofold. Firstly, we characterize the lack of compactness of the 2D Sobolev embedding into the different classes of Orlicz spaces. Secondly, we undertakethe study of the nonlinear Klein-Gordon equation with exponential growth, where the Orlicz norm plays a crucial role. In particular, issues of global existence, scattering and qualitativestudy are investigated.In the third part, we establish sharp Adams-type inequalities invoking Hardy inequalities, then we give a description of the lack of compactness of the Sobolev embeddings they induce

Full textLa información de clase semántica de los nombres es fundamental para una amplia variedad de tareas del procesamiento del lenguaje natural (PLN), como la traducción automática, la discriminación de referentes en tareas como la detección y el seguimiento de eventos, la búsqueda de respuestas, el reconocimiento y la clasificación de nombres de entidades, la construcción y ampliación automática de ontologías, la inferencia textual, etc. Una aproximación para resolver la construcción y el mantenimiento de los léxicos de gran cobertura que alimentan los sistemas de PNL, una tarea muy costosa y lenta, es la adquisición automática de información léxica, que consiste en la inducción de una clase semántica relacionada con una palabra en concreto a partir de datos de su distribución obtenidos de un corpus. Precisamente, por esta razón, se espera que la investigación actual sobre los métodos para la producción automática de léxicos de alta calidad, con gran cantidad de información y con anotación de clase como el trabajo que aquí presentamos, tenga un gran impacto en el rendimiento de la mayoría de las aplicaciones de PNL. En esta tesis, tratamos la adquisición automática de información léxica como un problema de clasificación. Con este propósito, adoptamos métodos de aprendizaje automático para generar un modelo que represente los datos de distribución vectorial que, basados en ejemplos conocidos, permitan hacer predicciones de otras palabras desconocidas. Las principales preguntas de investigación que planteamos en esta tesis son: (i) si los datos de corpus proporcionan suficiente información para construir representaciones de palabras de forma eficiente y que resulten en decisiones de clasificación precisas y sólidas, y (ii) si la adquisición automática puede gestionar, también, los nombres polisémicos. Para hacer frente a estos problemas, realizamos una serie de validaciones empíricas sobre nombres en inglés. Nuestros resultados confirman que la información obtenida a partir de la distribución de los datos de corpus es suficiente para adquirir automáticamente clases semánticas, como lo demuestra un valor-F global promedio de 0,80 aproximadamente utilizando varios modelos de recuento de contextos y en datos de corpus de distintos tamaños. No obstante, tanto el estado de la cuestión como los experimentos que realizamos destacaron una serie de retos para este tipo de modelos, que son reducir la escasez de datos del vector y dar cuenta de la polisemia nominal en las representaciones distribucionales de las palabras. En este contexto, los modelos de word embedding (WE) mantienen la “semántica” subyacente en las ocurrencias de un nombre en los datos de corpus asignándole un vector. Con esta elección, hemos sido capaces de superar el problema de la escasez de datos, como lo demuestra un valor-F general promedio de 0,91 para las clases semánticas de nombres de sentido único, a través de una combinación de la reducción de la dimensionalidad y de números reales. Además, las representaciones de WE obtuvieron un rendimiento superior en la gestión de las ocurrencias asimétricas de cada sentido de los nombres de tipo complejo polisémicos regulares en datos de corpus. Como resultado, hemos podido clasificar directamente esos nombres en su propia clase semántica con un valor-F global promedio de 0,85. La principal aportación de esta tesis consiste en una validación empírica de diferentes representaciones de distribución utilizadas para la clasificación semántica de nombres junto con una posterior expansión del trabajo anterior, lo que se traduce en recursos léxicos y conjuntos de datos innovadores que están disponibles de forma gratuita para su descarga y uso.
Lexical semantic class information for nouns is critical for a broad variety of Natural Language Processing (NLP) tasks including, but not limited to, machine translation, discrimination of referents in tasks such as event detection and tracking, question answering, named entity recognition and classification, automatic construction and extension of ontologies, textual inference, etc. One approach to solve the costly and time-consuming manual construction and maintenance of large-coverage lexica to feed NLP systems is the Automatic Acquisition of Lexical Information, which involves the induction of a semantic class related to a particular word from distributional data gathered within a corpus. This is precisely why current research on methods for the automatic production of high- quality information-rich class-annotated lexica, such as the work presented here, is expected to have a high impact on the performance of most NLP applications. In this thesis, we address the automatic acquisition of lexical information as a classification problem. For this reason, we adopt machine learning methods to generate a model representing vectorial distributional data which, grounded on known examples, allows for the predictions of other unknown words. The main research questions we investigate in this thesis are: (i) whether corpus data provides sufficient distributional information to build efficient word representations that result in accurate and robust classification decisions and (ii) whether automatic acquisition can handle also polysemous nouns. To tackle these problems, we conducted a number of empirical validations on English nouns. Our results confirmed that the distributional information obtained from corpus data is indeed sufficient to automatically acquire lexical semantic classes, demonstrated by an average overall F1-Score of almost 0.80 using diverse count-context models and on different sized corpus data. Nonetheless, both the State of the Art and the experiments we conducted highlighted a number of challenges of this type of model such as reducing vector sparsity and accounting for nominal polysemy in distributional word representations. In this context, Word Embeddings (WE) models maintain the “semantics” underlying the occurrences of a noun in corpus data by mapping it to a feature vector. With this choice, we were able to overcome the sparse data problem, demonstrated by an average overall F1-Score of 0.91 for single-sense lexical semantic noun classes, through a combination of reduced dimensionality and “real” numbers. In addition, the WE representations obtained a higher performance in handling the asymmetrical occurrences of each sense of regular polysemous complex-type nouns in corpus data. As a result, we were able to directly classify such nouns into their own lexical-semantic class with an average overall F1-Score of 0.85. The main contribution of this dissertation consists of an empirical validation of different distributional representations used for nominal lexical semantic classification along with a subsequent expansion of previous work, which results in novel lexical resources and data sets that have been made freely available for download and use.

A graph G = (V, E) is two-disjoint-cycle-cover [r1, r2]-pancyclic if for any integer l satisfying r1 ≤ l ≤ r2, there exist two vertex-disjoint cycles C1 and C2 in G such that the lengths of C1 and C2 are l and |V|− l, respectively, where |V| denotes the total number of vertices in G. On the basis of this definition, we further propose Ore-type conditions for graphs to be two-disjoint-cycle-cover vertex/edge [r1, r2]-pancyclic. In addition, we study cycle embedding in the n-dimensional locally twisted cube LTQn under the consideration of two-disjoint-cycle-cover vertex/edge pancyclicity.
