Resumen
In this thesis we present approaches to the creation and usage of semantic models by the analysis of the data spread in the feature space. We aim to introduce the general notion of using feature selection techniques in machine learning applications. The applied approaches obtain new feature directions on data, such that machine learning applications would show an increase in performance. We review three principle methods that are used throughout the thesis.

Sparse high dimensional time series are common in industry, such as in supply chain demand and retail sales. Accurate and reliable forecasting of high dimensional time series is essential for supply chain planning and business management. In practical applications, sparse high dimensional time series prediction faces three challenges: (1) simple models cannot capture complex patterns, (2) insufficient data prevents us from pursuing more advanced models, and (3) time series in the same dataset may have widely different properties. These challenges prevent the currently prevalent models and theo

The focus on machine learning and interactivity leads to a common theme of the need to balance conflicting requirements.

Second, interactive methods must balance minimal user demand with maximal user control. To address the problem of weak boundaries,methods of supervised texture classification are invest

Resumen
Gaussian process (GP) models are widely used to perform Bayesian nonlinear regression and classification tasks that are central to many machine learning problems. A GP is nonparametric, meaning that the complexity of the model grows as more data points are received. Another attractive feature is the behaviour of the error bars. They naturally grow in regions away from training data where we have high uncertainty about the interpolating function. In their standard form GPs have several limitations, which can be divided into two broad categories: computational difficulties for large data sets, a

Resumen
The ongoing processes of globalization and deregulation are changing the competitive framework in the majority of economic sectors. The appearance of new competitors and technologies entails a sharp increase in competition and a growing preoccupation among service providing companies with creating stronger bonds with customers. Many of these companies are shifting resources away from the goal of capturing new customers and are instead focusing on retaining existing ones. In this context, anticipating the customer¿s intention to abandon, a phenomenon also known as churn, and facilitating the la

Resumen
This thesis is concerned with two main areas: approximate inference in discrete graphical models, and random embeddings for dimensionality reduction and approximate inference in kernel methods. Approximate inference is a fundamental problem in machine learning and statistics, with strong connections to other domains such as theoretical computer science. At the same time, there has often been a gap between the success of many algorithms in this area in practice, and what can be explained by theory; thus, an important research effort is to bridge this gap. Random embeddings for dimensionality re

Resumen
Battery cells are the core of any electric vehicles (EV). It is important to get theaccurate value of different characteristics in a battery cell for safety and lifetime concern.And Two machine learning methods, support vector machine for regression(SVR) and multilayer perceptron (MLP) were introduced to improve the performanceof predicting the battery cell voltage using certain circuit related featureslike current, capacity and temperature on two different kinds of datasets. Differentconfigurations are validated using cross-validation to find the most suitable configurationof the parameters o

Resumen
Le sujet principal de mon doctorat est l'optimisation de la technologie de séparation membranaire. La technologie de séparation par membrane est souvent utilisée pour purifier les gaz et peut être utilisée dans différents aspects de l'industrie. Les performances de la séparation membranaire dépendent des conditions de fonctionnement et des interconnexions entre les équipements sélectionnés. Les membranes pour la séparation des gaz peuvent être fabriquées à partir de différents matériaux, et chaque matériau entraîne des performances de perméabilité différentes. Lorsqu'un mélange de gaz pénètre
