Résumé :

Graphical models are used to represent conditional independence relationships among variables by the means of a graph, with variables corresponding to graph's nodes. They are widely used in genomic studies, finance, energy forecasting, among other fields. More specifically, for a collection of q variables with conditional independence structure represented by an undirected graph, we assume that the underlying graph's structure is unknown. We are interested in inferring the graph's structure from data at hand. This procedure the bibliography is referred to as Structure Learning, where we use certain techniques for selecting a graphical model to depict conditional independence relationships between these q variables. We start from defining a model space which is consisted by a set of all possible graphical models; then we define a scoring function which enables us to score the different models of the model space and finally, we construct a search algorithm that will navigate through the model space to identify the optimal model that explains the problem at hand. The choice of a scoring function is crucial for optimizing the search procedure through the model space. Our approach to this problem is purely Bayesian for handling uncertainty in a more elaborate fashion. We will use estimates of posterior model probabilities for ranking the models at hand. The specification of a conditional prior on the column covariance matrix is not trivial because each graph under consideration induces a different independence structure and it affects the parameter space. Under this context, we cannot directly use improper priors, since they would result to indeterminate Bayes factors, thus we are required to carefully elicit a prior distribution under each graph, a task that becomes infeasible in higher dimensions. For creating an automated Bayesian scoring technique, we resort to Objective Bayes approaches, which are initiated by an improper prior distribution and their output is a fully usable prior distributions. In this thesis, we propose the use of two alternative Objective Bayes approaches for estimating posterior probabilities of models, namely the Expected Posterior prior approach and the Power-Expected Posterior Prior approach. Both approaches utilize the device of imaginary observations for providing usable prior distributions and are theoretically sounder than the Fractional Bayes Factor of O'Hagan. Our goal is to introduce both the Expected and Power-Expected Posterior prior approaches to the field of structure learning of undirected graphical models and evaluate their performance using certain stochastic search techniques. Diverse simulation scenarios are considered as well as a real-life data application.

Résumé :

Often we are confronted with heterogeneous multivariate data, i.e., data coming from several categories, and the interest may center on the differential structure of stochastic dependence among the variables between the groups. The focus in this work is on the two groups problem and is faced modeling the system through a Gaussian directed acyclic graph (DAG) couple linked in a fashion to obtain a joint estimation in order to exploit, whenever they exist, similarities between the graphs. The model can be viewed as a set of separate regressions and the proposal consists in assigning a non-local prior to the regression coefficients with the objective of enforcing stronger sparsity constraints on model selection. The model selection is based on Moment Fractional Bayes Factor, and is performed through a stochastic search algorithm over the space of DAG models.

Résumé :

Objective Bayesian methods have garnered considerable interest and support among statisticians, particularly over the past two decades. It has often been ignored, however, that in some cases the appropriate frequentist inference to match is a conditional one. We present various methods for extending the probability matching prior (PMP) methods to conditional settings. A method based on saddlepoint approximations is found to be the most tractable and we demonstrate its use in the most common exact ancillary statistic models. As part of this analysis, we give a proof of an exactness property of a particular PMP in location-scale models. We use the proposed matching methods to investigate the relationships between conditional and unconditional PMPs. A key component of our analysis is a numerical study of the performance of probability matching priors from both a conditional and unconditional perspective in exact ancillary models. In concluding remarks we propose many routes for future research.

Résumé :

Dans cette thèse, nous nous intéressons à l'optimisation combinatoire multi-objectif, et en particulier aux algorithmes évolutionnaires à base de décomposition. Ce type d'approches consiste à décomposer le problème multi-objectif original en plusieurs sous-problèmes mono-objectif, qui sont alors résolus de façon coopérative. Dans ce cadre, nous considérons la conception et l'analyse de nouveaux composants algorithmiques contribuant à la mise en place des fondations d'un framework d'optimisation à base de décomposition pour les problèmes combinatoires multi-objectif dits "boîte-noire", pour lesquels la forme analytique des fonctions objectif n'est pas connue de l'algorithme de résolution. Tout d'abord, nous étudions les éléments clés pour une meilleure répartition des efforts de calculs tout au long du processus d'optimisation. Pour cela, nous étudions l'impact conjoint de la taille de la population et du nombre de solutions générées par itération, tout en proposant différentes stratégies de sélection du ou des sous-problèmes à optimiser à chaque étape. Nous étudions ensuite différents mécanismes permettant de s'échapper des optima locaux. Ceux-ci s'inspirent de techniques issues de l'optimisation mono-objectif, et permettent d'améliorer considérablement le profil de convergence des approches considérées. Nous nous plaçons pour finir dans un contexte d'optimisation coûteuse, où l'évaluation de chaque solution s'avère particulièrement gourmande en temps de calcul, ce qui limite considérablement le budget alloué à l'optimisation. Pour cela, nous étudions de nouveaux composants s'appuyant sur des méta-modèles combinatoires, et nous considérons leur intégration au sein d'approches évolutionnaires multi-objectif basée sur la décomposition
In this thesis, we are interested in multi-objective combinatorial optimization, and in particular in evolutionary algorithms based on decomposition. This type of approaches consists in decomposing the original multi-objective problem into multiple single-objective sub-problems that are then solved cooperatively. In this context, we consider the design and the analysis of new algorithmic components contributing to the establishment of the foundations of an optimization framework based on decomposition for multi-objective combinatorial problems known as "black box", i.e., for which the analytical form of the objective functions is not available to the solving algorithm. First of all, we investigate the key components for a better distribution of the computational efforts during the optimization process. To this end, we study the joint impact of the population size and of the number of solutions generated at each iteration, while proposing different strategies for selecting one ore multiple sub-problem(s) to be optimized at each stage. We then study different mechanisms allowing to escape from local optima. They are inspired by techniques from single-objective optimization, and we show they can significantly improve the convergence profile of the considered approaches. Finally, we consider the context of expensive optimization, where the evaluation of each solution is particularly intensive in terms of computational resources. This hence drastically restrict the budget allocated to the optimization process. As such, we investigate new components based on combinatorial meta-models, and we consider their integration within decomposition-based multi-objective evolutionary approaches

Résumé :

New Zealand's Antarctic research station, Scott Base, is currently 100% reliant on aviation turbine fuel and existing diesel generator sets to produce the heat and electricity necessary to sustain staff activities. Decreasing fuel consumption at Scott Base has benefits economically, politically and environmentally. A method of reducing fuel consumption and increasing base independence that is receiving considerable attention from Antarctica New Zealand is the addition of wind power to the existing energy system. A performance-objective design of a wind-diesel hybrid energy system for Scott Base is proposed in order to determine the most effective hybrid system configuration with the lowest cost within a set of system constraints. A demand side management technique is also evaluated as a measure to further increase potential fuel savings. Modelling is completed using the simulation tool HOMER and results are presented for several different system configurations.

The infrastructure expansion planning in cellular networks, so called Base Station Placement (BSP) problem, is a challenging task that must consider a large set of aspects, and which cannot be expressed as a linear optimization function. The BSP is known to be a NP-hard problem unable to be solved by any deterministic method. Based on some fundamental assumptions of Long Term Evolution - Advanced (LTE-A) networks, this work proceeds to investigate the use of two methods for BSP optimization task: the Particle Swarm Optimization (PSO) and the Differential Evolution (DE), which were adapted for placement of many new network nodes simultaneously. The optimization process follows two multi-objective functions used as fitness criteria for measuring the performance of each node and of the network. The optimization process is performed in three scenarios where one of them presents actual data collected from a real city. For each scenario, the fitness performance of both methods as well as the optimized points found by each technique are presented

O processo de otimização é orientado por dois tipos de funções custo com multiobjetivos, que medem o desempenho dos novos nós individualmente e de toda a rede coletivamente. A otimização é realizada em três cenários, dos quais um deles apresenta dados reais coletados de uma cidade. Para cada cenário, são exibidos o desempenho dos dois algoritmos em termos da melhoria na função objetivo e os pontos encontrados no processo de otimização por cada uma das técnicas

Résumé :

I modelli grafici basati sull'utilizzo di grafi direzionati (Directed Acyclic Graphs, DAG) hanno acquisito negli ultimi decenni un'ampia popolarità per lo studio della dipendenza tra variabili in molteplici ambiti scientifici. Tipicamente lo scopo è fare inferenza su un modello attraverso i dati, ovvero misurare relazioni di dipendenza tra variabili. La famiglia di indipendenze (marginali) e condizionali codificate dal DAG determinano la sua proprietà markoviana. DAG che racchiudono le medesime indipendenze condizionali sono detti Markov equivalenti. È tuttavia noto che l'utilizzo di dati di natura puramente osservazionale non consenta di "distinguere" tra DAG Markov equivalenti. Questi sono quindi partizionati in classi di equivalenza, ciascuna delle quali viene rappresentata da un grafo a catena detto essential graph. Quando l'obiettivo è fare inferenza sul modello generatore dei dati è quindi più conveniente esplorare lo spazio degli essential graph (rispetto allo spazio dei DAG), sebbene la dimensione di questo cresca "più che esponenzialmente" nel numero di variabili (nodi del grafo). Per lungo tempo lo studio degli essential graph è stato quindi confinato a "dimensioni" modeste dello spazio. Tuttavia, per superare tale limite, negli ultimi anni sono stati proposti diversi metodi basati sull'utilizzo di catene di Markov. In diverse applicazioni (di carattere tipicamente biologico e genomico) si dispone di dati di tipo "interventistico", ossia prodotti a seguito di perturbazioni esogene di variabili o "esperimenti randomizzati". La nozione di intervento è strettamente legata all'interpretazione causale del DAG. Intervenendo su una variabile è possibile "rimuovere" la dipendenza di altre variabili sulla stessa, ossia modificare la proprietà markoviana del DAG. Questo determina una partizione dei DAG in classi di equivalenza di dimensione "più contenuta", ciascuna delle quali viene rappresentata da un interventional essential graph. Pertanto, laddove si disponga di dati di natura interventistica, la selezione del modello generatore dei dati può essere rivolta all'esplorazione di tale spazio; in tal modo è possibile "migliorare" l'identificazione del DAG generatore dei dati. Nel presente lavoro si affronta il problema della selezione di modelli grafici gaussiani attraverso una metodologia di tipo bayesiano. Nello specifico, si adotta un approccio oggettivo basato sulla nozione di fractional Bayes factor. A questo scopo, ricaviamo una formula per il calcolo della verosimiglianza marginale di un interventional essential graph in presenza di dati di natura osservazionale e interventistica. In seguito, procediamo alla costruzione di una catena di Markov per l'esplorazione dello spazio degli interventional essential graph sotto condizioni di sparsità. Proponiamo quindi un algoritmo di tipo MCMC per approssimare la posterior distribution degli interventional essential graph e "quantificare" misure di incertezza come la probabilità di inclusione di un edge. Applichiamo infine la metodologia proposta, denominata Objective Bayesian Interventional Essential graph Search, a studi di simulazione e per l'analisi di protein-signaling data, laddove dati di natura interventistica corrispondono a rilevazioni effettuate sotto differenti condizioni sperimentali.
Graphical models based on Directed Acyclic Graphs (DAGs) are a very common tool in many scientific areas for the investigation of dependencies among variables. Typically, the objective is to infer models from the data or measuring dependence relationships between variables. The set of all (marginal and) conditional independencies encoded by a DAG determines its Markov property. However, it is well known that we cannot distinguish between DAGs encoding the same set of conditional independencies (Markov equivalent DAGs) using observational data. Markov equivalent DAGs are then collected in equivalence classes each one represented by an Essential Graph (EG), also called Completed Partially Directed Graph (CPDAG). When the interest is in model selection it is then convenient to explore the EG space, rather than the whole DAG space, even if the number of EGs increases super-exponentially with the number of vertices. An exhaustive enumeration of all EGs is not feasible and so structural learning in the EG space has been confined to small dimensional problems. However, to avoid such limit, several methods based on Markov chains have been proposed in recent years. In many applications (such as biology and genomics) we have both observational and interventional data produced after an exogenous perturbation of some variables or from randomized intervention experiments. The concept of intervention is strictly related to the causal interpretation of a DAG. Interventions destroy the original causal dependency on the intervened variables and modify the Markov property of a DAG. This results in a finer partition of DAGs into equivalence classes, each one represented by an Interventional Essential Graph (I-EG). Hence, model selection of DAGs in the presence of observational and interventional data can be performed over the I-EG space, thus improving the identifiability of the true data generating model. In this work we deal with the problem of Gaussian DAG model selection from a Bayesian perspective. In particular, we adopt an objective Bayes approach based on the notion of fractional Bayes factor. We then obtain a closed formula to compute the marginal likelihood of an I-EG given a collection of observational and interventional data. Next, we construct a Markov chain to explore the I-EG space possibly accounting for sparsity constraints. Hence, we propose an MCMC algorithm to approximate the posterior distribution of I-EGs and provide a quanti_cation of inferential uncertainty by measuring some features of interest, such as probabilities of edge inclusion. We apply our methodology, that we name Objective Bayesian Interventional Essential graph Search (OBIES) to simulation settings and to the analysis of protein-signaling data, where interventional data consists in a collection of observations measured under different experimental conditions.

In this CIFRE thesis, a collaboration between the Center of Mathematics and their Applications, École Normale Supérieure de Cachan and the company DxO, we tackle the problem of the additive decomposition of an image into base and detail. Such a decomposition is a fundamental tool in image processing. For applications to professional photo editing in DxO Photolab, a core requirement is the absence of artifacts. For instance, in the context of contrast enhancement, in which the base is reduced and the detail increased, minor artifacts becomes highly visible. The distortions thus introduced are unacceptable from the point of view of a photographer.The objective of this thesis is to single out and study the most suitable filters to perform this task, to improve the best ones and to define new ones. This requires a rigorous measure of the quality of the base plus detail decomposition. We examine two classic artifacts (halo and staircasing) and discover three more sorts that are equally crucial: contrast halo, compartmentalization, and the dark halo. This leads us to construct five adapted patterns to measure these artifacts. We end up ranking the optimal filters based on these measurements, and arrive at a clear decision about the best filters. Two filters stand out, including one we propose

Through a brief analysis of the historical origins of the contract, taking into account as party settlements with the State endorsement, observed in its practical applications, we intend to analyze the collapse in the objective basis of contracts, verifying the consequence of such breakaway, both in the jurisprudence as in the social relations involved, and as the interpretative possibilites of such issue. The relevance of the subject is shown by itself, once the contemporary society is contractarian in almost all respects, and the non compliance of the contractual terms is a result of numerous disorders that cause impact on the harmony of social life in all spheres: familiar level up to the governmental. Themes such as autonomy and contractual liberty come up against issues that need ethical-political reviews. As the main objective remains the characterization of how, when and under what circumstances it is possible to affirm that there was a collapse in the objective basis of the contract, and diagnosed such collapse, how to proceed in such situation: there will be a possibility of establishing a new agreement or just be left to setting penalties and compensations. The secondary objectives point to the identification of direct and indirect effects regarding the situation, and in the action of laws to this type of occurrence. The method that will be used is the deductive method in order to develop the research, being the review of literature on the theme the basic source to enrich discussions in the invitation to authors that have already leaned on the theme in books, articles, theses and further dissertations
Por meio de uma sucinta análise das origens históricas do contrato, considerado enquanto acerto de partes com aval do Estado, observado em suas aplicações práticas, pretende-se analisar a quebra da base objetiva dos contratos, verificando as consequências desta ruptura tanto na jurisprudência como nas relações sociais envolvidas, bem como as possibilidades interpretativas da questão. A relevância do tema se demonstra por si só, vez que a sociedade contemporânea é contratualista em quase todos os aspectos, e a não observância dos termos contratuais é causa de inúmeros transtornos que impactam sobre a harmonia da vida social em todas as esferas: do nível familiar ao governamental. Temas como a autonomia e a liberdade contratual esbarram em questões que necessitam de revisões ético-políticas. Como objetivo principal subsiste a caracterização de como, quando e em que circunstâncias se pode alegar que houve a quebra da base objetiva do contrato, e, diagnosticada esta quebra como se procede diante da situação: haverá possibilidade do estabelecimento de novo acordo ou apenas restará a configuração de penas e ressarcimentos. Os objetivos secundários apontam para a identificação de efeitos diretos e indiretos da situação, e na ação das leis para este tipo de ocorrência. Será utilizado o método dedutivo para o desenvolvimento da pesquisa, sendo a revisão da literatura sobre o tema a fonte básica para o enriquecimento das discussões, no convite a autores que já se debruçaram sobre o assunto em livros, artigos, teses e demais dissertações

Résumé :

AbstractIn order to assess new and often costly treatments, the need for objective scar measurement tools has become increasingly important. A combination of subjective and objective measures should be the aim of every researcher. Quantitative assessment of scars requires devices to measure their physical and physiological properties. Physiological scar parameters are scar characteristics relevant to pathological scarring which cannot be seen with the bare eye. This also means that they can only be assessed with objective assessment tools.Skin hydration is defined as the water content of the epidermis and the dermis, and the ability of the skin to retain water is important to avoid dry appearance of the skin and prolonged inflammation in scarring. Many approaches exist to measure skin water content. One single method is often not enough to capture all the relevant information. Trans-epidermal water loss, stratum corneum water content, and dermal water content are equally important and related to each other.Scar maturation has been related to transcutaneous oxygen tension, and it is hypothesized that low levels of transcutaneous oxygen pressure in evolving scars result from low oxygen diffusibility through scar tissue.Tactile sensitivity of the skin can be measured by esthesiometers. The Semmes-Weinstein monofilament test is found to be a feasible and reliable outcome measure to evaluate touch perception threshold in older upper extremities burn scars.

Résumé :

The paper describes an experimental assessment of the transient performance of a multi-objective adaptive approach to the control of flexible rotors previously presented by the authors. The approach is applicable to any form of controllable bearings or actuators. In the case reported here, the rotor is supported by active magnetic bearings (AMBs). The theory underlying the controller is outlined: the objectives include minimization of the forces transmitted to the base while restricting rotor vibrations to a user-defined limit. A third objective is to prevent rotor contact with the auxiliary bearings used to protect the active elements. These three objectives are met by a two-stage weighting strategy followed by the adaptive control of two parameters that automatically and continuously adjust the weightings of individual objective functions to satisfy user defined performance criteria.

Résumé :

In this paper, an automated framework is presented to perform helicopter rotor blade planform optimization. This framework contains three elements, Dakota, ParBlade, and RCAS. These elements are integrated into an environment control tool, Galaxy Simulation Builder, which is used to carry out the optimization. The main objective of this work is to conduct rotor performance design optimizations for forward flight and hover. The blade design variables manipulated by ParBlade are twist, sweep, and anhedral. The multi-objective genetic algorithm method is used in this study to search for the optimum blade design; the optimization objective is to minimize the rotor power required. Following design parameter substitution, ParBlade generates the modified blade shape and updates the rotor blade properties in the RCAS script before running RCAS. After the RCAS simulations are complete, the desired performance metrics (objectives and constraints) are extracted and returned to the Dakota optimizer. Demonstrative optimization case studies were conducted using a UH-60A main rotor as the base case. Rotor power in hover and forward flight, at advance ratio 𝜇𝜇 = 0.3, are used as objective functions. The results of this study show improvement in rotor power of 6.13% and 8.52% in hover and an advance ratio of 0.3, respectively. This configuration also yields greater reductions in rotor power for high advance ratios, e.g., 12.42% reduction at 𝜇𝜇 = 0.4.

Texte intégral

Résumé :

Science reviews are an essential cornerstone of all excellent science programs and are a requirement of monitoring programs within the Inventory and Monitoring Division of the National Park Service (NPS). Science reviews provide necessary professional critique of objectives, study design, data collection, analysis, scientific interpretation, and how effectively information is transferred to target audiences. Additionally, reviews can help identify opportunities to cooperate more effectively with interested and vested partners to expand the impacts of collective findings across larger landscapes. In December 2020, seven biologists from USGS, USFWS, and NPS provided a critical review of the Greater Yellowstone Network Amphibian Monitoring Protocol for monitoring Columbia spotted frogs (Rana luteiventris), boreal chorus frogs (Pseudacris maculata), western toads (Anaxyrus boreas), western tiger salamanders (Ambystoma mavortium), and environmental conditions at wetland sites clustered within watershed units in Yellowstone and Grand Teton national parks. This review followed sixteen years of GRYN amphibian and wetland monitoring, allowing us to evaluate the impact of the work thus far and to discuss potential improvements to the protocol. Reviewers were asked to assess the following amphibian monitoring objectives per Bennetts et al. (2013, Cooperative amphibian monitoring protocol for the Greater Yellowstone Network: Narrative, version 1.0, https://irma.nps.gov/DataStore/Reference/Profile/2194571) and to assess the degree to which GRYN is meeting the objectives based on the current sampling, analyses, and reporting: Objective 1: Estimate the proportion of catchments and wetland sites used for breeding by each of the four common, native amphibian species annually, and estimate the rate at which their use is changing over time. Objective 2: Determine the total number of wetlands within sampled catchments that are suitable for amphibian breeding (i.e., have standing water during the breeding season) annually. Objective 3: For western toads, estimate the proportion of previously identified breeding areas that are used annually, and estimate the rate at which their use may be changing over time. Generally, reviewers commended the GRYN Amphibian Monitoring Program, including the design, the statistical rigor of current analytical approaches, the large number of monitoring reports and publications, and the audiences reached. Reviewers unanimously felt that the first two objectives of this protocol are being met for two species (Columbia spotted frogs and boreal chorus frogs) in medium- and high-quality catchments, and all but one reviewer also felt these objectives are being met for western tiger salamanders. It was universally recognized that objective 3 for western toads is not being met but reviewers attributed this to issues related to funding and capacity rather than design flaws. Reviewers felt the current design provides an adequate base for parlaying additional work and offered suggestions focused on increasing efficiencies, maximizing information that can be collected in the field, strengthening analyses, and improving scientific outreach. In this document, we summarize reviewers' comments and include their full written reviews in Appendix B.

Texte intégral

Résumé :

The main objective of this project was to initiate a breeding program to produce cold-tolerant and salinity-tolerant synthetic breeds of tilapia, from a base population consisting of a four-species hybrid population created under an earlier BARD project. A secondary objective was to estimate genetic parameters for the traits growth rate under fresh- and salt-water and for cold tolerance. A third objective was to place quantitative trait loci that affect these traits of interest (e.g., growth rate in fresh-water, salt-water and cold tolerance) on the growing linkage map of primarily microsatellite loci. We have encountered fertility problems that were apparently the result of the complex genetic structure of this base population. The failure in producing the first generation of the breeding program has forced us to stop the intended breeding program. Thus, upon approval of BARD office, this objective was dropped and during the last year we have focused on the secondary objective of the original project during the third year of the project, but failed to perform the intended analysis to estimate genetic parameters for the traits of interest. We have succeeded, however, to strengthen the earlier identification of a QTL for cold tolerance by analyzing further segregating families. The results support the existence of a QTL for cold tolerance on linkage group 15, corresponding to UNH linkage group 23. The results also indicate a QTL for the same trait on linkage group 12, corresponding to UNH linkage group 4.
