The term stochastic is defined as having a random probability distribution or pattern that may be analyzed statistically but may not be predicted precisely. A stochastic model attempts to estimate outcomes while allowing a random variation in one or more inputs over time. These models are used across a number of fields from gene expression in biology, to stock, asset, and insurance analysis in finance. In this thesis, we will build up the basic probability theory required to make an ``optimal estimate", as well as construct the stochastic integral. This information will then allow us to introduce stochastic differential equations, along with our overall model. We will conclude with the "optimal estimator", the Kalman Filter, along with an example of its application.

Повний текст джерелаSome independent software vendors might not endure the reduction in revenue and increased costs associated when they switch software license models. The lack of identified and prioritized complexities might lead to potential increased revenue loss or prevent small and medium-sized independent software vendors within the United States from migrating from perpetual software licensing to subscription-based models. The purpose of this qualitative case study was to explore, document, and describe organizational complexities and their prioritization in contributing to the failure or success of software license model migration. The research questions for this qualitative case study included a Primary Research Question: What complexities can senior management of small and medium-sized independent software vendors (ISV) encounter when migrating from a perpetual license model to a subscription-based licensing model? Supporting Research Question 1: What is the prioritization of the complexities determined to be a factor in the migration of software licensing models? Supporting Research Question 2: How do identifying and prioritizing complexities affect decision-making to mitigate potential initial revenue loss? For this study, eight managers were recruited from a small to medium sized independent software vendor. Specifically, participants in the sample were managers who have worked within the software industry for at least four years, had knowledge of the company’s existing software license model, and were involved in the consideration of migrating from a perpetual license model to a subscription-based licensing model. The data collection methods for this research were face-to-face interviews, a focus group, and direct observations. The multi-criteria decision analysis theory and diffusion of influence theory served as the conceptual framework for this research. The framework provided a model for software vendor executives to identify and prioritize complexities and reduce the initial loss of revenue during license migration. Eight themes emerged: financial, go-to-market, infrastructure, reorganization, security, training, and unknown strategy. There was a consistency between the themes and literature. The data was consistent with the multi-criteria decision and diffusion of influence theories. The results indicated four key findings: support functions were less aware of complexities, no evidence of a clear strategic plan was present, the most significant complexity anticipated was the go-to-market complexity, and there was a direct effect on decision-making in identifying and prioritizing complexities. Exploring and understanding the totality of complexities an independent software vendor may encounter, the prioritization of those complexities, and adjusting decision-making to compensate for those complexities, while establishing and following a communicated strategic plan may significantly reduce the potential for financial loss, increase market positioning and competitive advantage. The results and limitations may provide areas for future research. Future studies should seek to conduct similar studies with multiple independent software vendors to provide additional levels of validation and reliability. Such studies should include independent software vendors who have successfully and unsuccessfully migrated license models.
Gaier, Adam. "Accelerating Evolutionary Design Exploration with Predictive and Generative Models." Electronic Thesis or Diss., Université de Lorraine, 2020. http://www.theses.fr/2020LORR0087.
Повний текст джерелаOptimization plays an essential role in industrial design, but is not limited to minimization of a simple function, such as cost or strength. These tools are also used in conceptual phases, to better understand what is possible. To support this exploration we focus on Quality Diversity (QD) algorithms, which produce sets of varied, high performing solutions. These techniques often require the evaluation of millions of solutions -- making them impractical in design cases. In this thesis we propose methods to radically improve the data-efficiency of QD with machine learning, enabling its application to design. In our first contribution, we develop a method of modeling the performance of evolved neural networks used for control and design. The structures of these networks grow and change, making them difficult to model -- but with a new method we are able to estimate their performance based on their heredity, improving data-efficiency by several times. In our second contribution we combine model-based optimization with MAP-Elites, a QD algorithm. A model of performance is created from known designs, and MAP-Elites creates a new set of designs using this approximation. A subset of these designs are the evaluated to improve the model, and the process repeats. We show that this approach improves the efficiency of MAP-Elites by orders of magnitude. Our third contribution integrates generative models into MAP-Elites to learn domain specific encodings. A variational autoencoder is trained on the solutions produced by MAP-Elites, capturing the common “recipe” for high performance. This learned encoding can then be reused by other algorithms for rapid optimization, including MAP-Elites. Throughout this thesis, though the focus of our vision is design, we examine applications in other fields, such as robotics. These advances are not exclusive to design, but serve as foundational work on the integration of QD and machine learning

Повний текст джерелаNoC-based MPSoCs can provide massive computing power on a single chip, achieving hundreds of billions of operations per second by employing dozens of processing cores that communicate over a packet-switched network at a rate that exceeds 100 Tbps. Such devices can support the convergence of several appliances (e. g. HDTV, multiple wireless communication standards, media players, gaming) due to their comparatively high performance, flexibility and power efficiency. Due to the vast design space alternatives, evaluating the NoC-based MPSoCs at lower abstraction levels does not provide the required support to find out the most efficient NoC architecture considering the performance constraints (e. g. latency, power) of a given application at early design process stages. Thus, NoC-based MPSoCs design requires simple and accurate high level models in order to achieve precise performance results, of each design alternative, in an acceptable design time. In this context, the present Thesis has two main contributions: (i) development of abstract NoC models, providing accurate performance evaluation; and (ii) integration of the proposed models into a model-based design flow, allowing the design space exploration of NoC-based MPSoCs at early stages of the design flow.
MPSoCs baseados em NoCs podem fornecer alto desempenho em um único circuito integrado, atingindo centenas de bilhões de operações por segundo através do emprego de múltiplos elementos de processamento que se comunicam através de uma NoC operando a uma freqüência que excede 100 Tbps. Tais dispositivos podem suportar a execução simultânea de múltiplas aplicações (e. g. HDTV, múltiplos padrões de comunicação sem fio, tocadores multimídia, jogos), devido a características como alto desempenho, flexibilidade e eficiência em termos de consumo de energia. Devido a quantidade de alternativas inerentes ao grande espaço de projeto, a avaliação de MPSoCs baseados em NoCs em baixo níveis de abstração não prove o suporte necessário para encontrar a melhor arquitetura para a NoC considerando métricas de desempenho (e. g. latência, potência) de uma dada aplicação nas fases iniciais de projeto. Dessa forma, o projeto de MPSoCs baseados em NoCs requer modelos simples e precisos em alto nível de abstração, os quais possam gerar resultados precisos de desempenho, de cada alternativa de projeto, em um tempo de projeto razoável. Neste contexto, a presente Tese tem duas contribuições principais: (i) desenvolvimento de modelos de NoC abstratos, e (ii) integração dos modelos propostos dentro de um fluxo de projeto baseado em modelos, permitindo assim a exploração do espaço de projeto de MPSoCs baseados em NoCs nas fases iniciais do fluxo projeto.

Повний текст джерелаIndependent Component Analysis (ICA) models a set of signals as linear combinations of independent sources. This analysis method plays a key role in electroencephalography (EEG) and magnetoencephalography (MEG) signal processing. Applied on such signals, it allows to isolate interesting brain sources, locate them, and separate them from artifacts. ICA belongs to the toolbox of many neuroscientists, and is a part of the processing pipeline of many research articles. Yet, the most widely used algorithms date back to the 90's. They are often quite slow, and stick to the standard ICA model, without more advanced features.The goal of this thesis is to develop practical ICA algorithms to help neuroscientists. We follow two axes. The first one is that of speed. We consider the optimization problems solved by two of the most widely used ICA algorithms by practitioners: Infomax and FastICA. We develop a novel technique based on preconditioning the L-BFGS algorithm with Hessian approximation. The resulting algorithm, Picard, is tailored for real data applications, where the independence assumption is never entirely true. On M/EEG data, it converges faster than the `historical' implementations.Another possibility to accelerate ICA is to use incremental methods, which process a few samples at a time instead of the whole dataset. Such methods have gained huge interest in the last years due to their ability to scale well to very large datasets. We propose an incremental algorithm for ICA, with important descent guarantees. As a consequence, the proposed algorithm is simple to use and does not have a critical and hard to tune parameter like a learning rate.In a second axis, we propose to incorporate noise in the ICA model. Such a model is notoriously hard to fit under the standard non-Gaussian hypothesis of ICA, and would render estimation extremely long. Instead, we rely on a spectral diversity assumption, which leads to a practical algorithm, SMICA. The noise model opens the door to new possibilities, like finer estimation of the sources, and use of ICA as a statistically sound dimension reduction technique. Thorough experiments on M/EEG datasets demonstrate the usefulness of this approach.All algorithms developed in this thesis are open-sourced and available online. The Picard algorithm is included in the largest M/EEG processing Python library, MNE and Matlab library, EEGlab

Повний текст джерелаIn this thesis, we first present an original point of view for the state of the art on methods developed for interpreting gene expression results through corresponding gene annotations. Then, we tackle the non-supervised learning issue of class discovery among gene expression profiles, and we propose two specific approaches on this subject: CGGA (Co-expressed Gene Groups Analysis) and GENMINER (Gene-integrated analysis using association rules mining). CGGA is a knowledge-based approach which automatically integrates gene expression profiles and gene annotations obtained from genome-wide information databases such as Gene Ontology. GENMINER is a co-clustering and bi-clustering approach which automatically integrates at once gene annotations and gene expression profiles to discover intrinsic associations between these two heterogeneous sources of information. Finally, we focus on the supervised learning issue of class prediction, and we propose GENETREE (GENE-integrated analysis for biological sample prediction using decision TREEs), an approach which takes advantage of the well known decision tree algorithm C5. 0 and adapts its entropy splitting principle with several ontology-based criteria

Повний текст джерелаLas plataformas de redes sociales en lı́nea sirven como importantes fuentes de información acerca de lo que está pasando en el mundo y cómo la gente reacciona a estos eventos. Dentro de toda la información útil que los cientı́ficos han extraı́do de estos repositorios, el análisis de mensajes relacionados con eventos del mundo real son una importante oportunidad para realizar análisis histórico de noticias. Como los mensajes publicados en estas plataformas contienen distintos puntos de vista de una noticias, contribuyen con información que quizás no haya sido publicada por los medios tradicionales. Dentro de los aspectos que se pueden estudiar de un evento noticioso, las relaciones geopolı́ticas como consecuencia de ellos contienen información valiosa para análisis histórico futuro. En efecto, entender las relaciones entre paı́ses, su desarrollo en el tiempo y cómo las personas reaccionaron a ellas es esencial para comprender el presente. Sin embargo, extraer información útil desde estas plataformas no es una tarea fácil dada la creciente velocidad de publicación de sus mensajes, lo no estruturado de su contenido y la enormidad de repositorios que generan. Por otra parte, para extraer conocimiento nuevo se necesitan herramientas que permitan la generación de hipótesis nuevas por parte de expertos en un dominio. Esta necesidad de colaboración entre sistemas computacionales y usuarios finales hace que el problema tenga dos componentes. El primer componente es que los datos pueden ser difı́ciles de guardar, recuperar y procesar sin las representaciones adecuadas de alto nivel. El segundo componente es que explorar con ojos humanos un gran número de mensajes puede ser imposible sin las herramientas adecuadas. El objetivo de esta tesis es abordar estos dos problemas. El primer problema, relacionado con la eficiencia del procesamiento computacional de los datos, se aborda presentando una representación de alto nivel de eventos noticiosos en su contexto geopolı́tico. Más especı́ficamente, proponemos una representación de eventos consciente del contexto espacio temporal que incorpora tanto la información de las ubicaciones que están involucradas en el mundo real como de aquellas hasta donde se propagó el evento. Exploramos la utilidad de este modelo usando datos de eventos noticiosos extraı́dos desde Twitter en una ventana de tiempo de dos años. Abordamos el segundo problema, relacionado con la exploración de mensajes por expertos en un dominio, diseñando herramientas visuales para exporarlas. Primero diseñamos una interfaz web visual, llamada Galean, que permite a usuarios explorar noticias dada la representación de eventos anteriormente mencionada. Evaluamos esta interfaz a través de un estudio cualitativo con potenciales usuarios finales y uno cuantitativo con 30 participantes. Dada la retroalimentación recibida en esas instancias, diseñamos y evaluamos una nueva manera de visualizar datos geográficos y temporales llamada Cartoglyphs.

Повний текст джерелаOs modelos elevated plus-maze e light/dark são amplamente utilizados no estudo de compostos ansiolíticos e dos mecanismos neurobiológicos de ansiedade. O elevated plus-maze (EPM) e o open-field (OF) são testes validados para avaliação da ansiedade em ratos e ratinhos. O teste ligh/dark (LD) também é utilizado nos modelos de ansiedade, no entanto, só foi validado para modelos em ratinhos. Para validar o teste LD como um modelo de ansiedade em ratos avaliaram-se os parâmetros: validade construtiva, validade exterior e validade preditiva. Estes parâmetros foram analisados através de avaliações comportamentais. neuroquímicas e hormonais na presença e ausência de compostos ansiolíticos, e de uma análise comparativa destas avaliações nos testes EPM e LD. Foi ainda estabelecida uma análise comparativa dos dados comportamentais entre o teste OF e os testes EPM e LD. Cada rato (estirpe Wistar) (200-220g) foi colocado no centro do aparelho OF e deixado a explorá-lo durante 20 minutos. Os primeiros 5 minutos foram utilizados para avaliar os comportamentos de ansiedade e os últimos 15 minutos para avaliar a actividade locomotora. Uma semana depois cada rato foi colocado no aparelho EPM (n=6) ou no aparelho LD (n=6) durante 5 minutos. Foram ainda submetidos a estes testes, na mesma ordem, indivíduos tratados com diazepam (0,5mg/kg) (n=6 para cada teste) e propranolol (10mg/kg) (n=6 para cada teste) numa solução de soro fisiológico de 2ml/kg e indivíduos tratados com soro fisiológico (n=6 para cada teste). As sessões experimentais foram registadas por uma câmara de vídeo colocada um metro acima do aparelho e as medidas comportamentais foram registadas e analisadas utilizando o software Noldus Observer. Imediatamente após cada sessão de EPM ou LD os animais foram sacrificados, tendo-se recolhido sangue para doseamento hormonal e dissecado a amígdala e o hipocampo para posterior análise neuroquímica. As concentrações de dopamina (DA), serotonina (5-HT) e dos seus metabolitos foram quantificadas por cromatografia líquida de alta performance combinada com detecção electroquímica. Os níveis de corticosterona no plasma foram medidos por ensaio imunoenzimático. Os resultados comportamentais mostram que os testes EPM e LD induzem respostas comportamentais semelhantes sugerindo que os comportamentos registados nos testes reflectem o mesmo estado psicológico - ansiedade. Esta generalização das respostas comportamentais em diferentes modelos de ansiedade contribui para uma possível validade construtiva do modelo LD para ratos. No entanto, este parâmetro de validade é comprometido pelos resultados neuroquímicos destes animais uma vez que não revelam alterações nas concentrações das monoaminas nas áreas cerebrais analisadas. Por outro lado, a semelhança dos resultados neuroquímicos nos testes LD e EPM indica que estes testes são muito influenciáveis pelas condições e procedimentos usados, uma ideia reforçada pelo aumento dos níveis de serotonina no hipocampo dos indivíduos injectados com soro. Estes resultados evidenciam a importância e a necessidade de uniformizar protocolos e de controlar cautelosamente os procedimentos em todas a etapas da experiência, para possibilitar a utilização destes modelos como indutores de ansiedade. O diazepam e o propranolol não causaram efeitos ansiolíticos nas respostas comportamentais, no entanto, não podemos esquecer que as doses aplicadas são inferiores às utilizadas noutros estudos que mostraram efeitos ansiolíticos. Por outro lado, os dados relativos aos efeitos dos agentes ansiolíticos mostram que os fármacos têm efeitos opostos no rato, tanto no EPM como no LD. Além disso, esse efeito reflecte-se a nível comportamental e neuroquímico. A nível comportamental o diazepam induziu uma redução do estado de alerta enquanto que o propanolol induziu um aumento do estado de alerta. A nível neuroquímico o diazepam induziu uma diminuição dos níveis de serotonina no hipocampo ao contrário do propranolol que induziu um aumento dos níveis de serotonina na mesma área cerebral. Estes resultados sugerem que o propranolol parece ter um efeito ansiogénico originado pela manipulação dos animais aliada ao bloqueio, pelo propranolol, dos processos de reconsolidação da memória activa, o que eliminou os efeitos de habituação ao stress induzido pela manipulação. Estas alterações neuroquimicas foram observadas apenas nos ratos expostos ao EPM indicando que o EPM e o LD desencadeiam aspectos distintos de ansiedade. Estes resultados comprometem a validade preditiva do modelo mas os procedimentos realizados são insuficientes para concluir acerca deste parâmetro. Nas respostas hormonais produzidas por estes testes não foi verificado um aumento nos níveis de corticosterona após a exposição aos testes de ansiedade, no entanto, estes dados podem ter sido influenciados por aspectos da variação circadiana o que torna difícil inferir sobre o critério de validade exterior. A heterogeneidade das formas patológicas de ansiedade existentes toma difícil que um modelo de ansiedade reúna os 3 critérios de validade, no entanto, este trabalho indica que o modelo LD não é um modelo de ansiedade ideal para ratos. Os resultados deste estudo são mais uma contribuição para a evidência crescente da importância e necessidade de uma análise complexa baseada em observações comportamentais no aperfeiçoamento da credibilidade e sensibilidade destes modelos animais.

Повний текст джерелаDiese Diplomarbeit behandelt echtzeitfähige Renderingverfahren für 3D Informationslinsen, die auf der Fokus-&-Kontext-Metapher basieren. Im folgenden werden ihre Anwendbarkeit auf Objekte und Strukturen von virtuellen 3D-Stadtmodellen analysiert, konzipiert, implementiert und bewertet. Die Focus-&-Kontext-Visualisierung für virtuelle 3D-Stadtmodelle ist im Gegensatz zum Anwendungsbereich der 3D Geländemodelle kaum untersucht. Hier jedoch ist eine gezielte Visualisierung von kontextbezogenen Daten zu Objekten von großer Bedeutung für die interaktive Exploration und Analyse. Programmierbare Computerhardware erlaubt die Umsetzung neuer Linsen-Techniken, welche die Steigerung der perzeptorischen und kognitiven Qualität der Visualisierung im Vergleich zu klassischen perspektivischen Projektionen zum Ziel hat. Für eine Auswahl von 3D-Informationslinsen wird die Integration in ein 3D-Szenengraph-System durchgeführt: • Verdeckungslinsen modifizieren die Gestaltung von virtuellen 3D-Stadtmodell- Objekten, um deren Verdeckungen aufzulösen und somit die Navigation zu erleichtern. • Best-View Linsen zeigen Stadtmodell-Objekte in einer prioritätsdefinierten Weise und vermitteln Meta-Informationen virtueller 3D-Stadtmodelle. Sie unterstützen dadurch deren Exploration und Navigation. • Farb- und Deformationslinsen modifizieren die Gestaltung und die Geometrie von 3D-Stadtmodell-Bereichen, um deren Wahrnehmung zu steigern. Die in dieser Arbeit präsentierten Techniken für 3D Informationslinsen und die Anwendung auf virtuelle 3D Stadt-Modelle verdeutlichen deren Potenzial in der interaktiven Visualisierung und bilden eine Basis für Weiterentwicklungen.

Повний текст джерелаTo face their competitive stakes, existing companies are incentivized to renew their business model. Meanwhile, more and more innovation venues are being developed within them. In this thesis, we study how this places- which we call corporate collaborative innovation spaces (CIS)- contribute to the exploration of new business models.A lengthwise ethnographic case study within Altran company explores CIS’s place in the organisation, their real activities around customers and the use of artifacts/equipments made available to users.The results show the managerial innovation dimension- result of the organisational ambidextrous nature-of these CIS, decipher the micro processes leading to the emergence of a new value proposition / customer relationship and situate the demonstrators’ role in the construction of a discourse offering a new customer experience to visitors.We thus foster an understanding of CIS’s functioning and contribute to the enrichment of Business Model’s innovation theories, particularly in their multidimensional and systemic perspectives. We conclude by proposing ways to optimize the use of CIS through better appropriation by internal resources, particularly the sales force

Повний текст джерелаDescribing the co-variations between several observed random variables is a delicate problem. Dependency networks are popular tools that depict the relations between variables through the presence or absence of edges between the nodes of a graph. In particular, conditional correlation graphs are used to represent the “direct” correlations between nodes of the graph. They are often studied under the Gaussian assumption and consequently referred to as “Gaussian Graphical Models” (GGM). A single network can be used to represent the overall tendencies identified within a data sample. However, when the observed data is sampled from a heterogeneous population, then there exist different sub-populations that all need to be described through their own graphs. What is more, if the sub-population (or “class”) labels are not available, unsupervised approaches must be implemented in order to correctly identify the classes and describe each of them with its own graph. In this work, we tackle the fairly new problem of Hierarchical GGM estimation for unlabelled heterogeneous populations. We explore several key axes to improve the estimation of the model parameters as well as the unsupervised identification of the sub-populations. Our goal is to ensure that the inferred conditional correlation graphs are as relevant and interpretable as possible. First - in the simple, homogeneous population case - we develop a composite method that combines the strengths of the two main state of the art paradigms to correct their weaknesses. For the unlabelled heterogeneous case, we propose to estimate a Mixture of GGM with an Expectation Maximisation (EM) algorithm. In order to improve the solutions of this EM algorithm, and avoid falling for sub-optimal local extrema in high dimension, we introduce a tempered version of this EM algorithm, that we study theoretically and empirically. Finally, we improve the clustering of the EM by taking into consideration the effect of external co-features on the position in space of the observed data
