Der volle Inhalt der QuelleNowadays, storage and data processing systems are supposed to store and process large time series. As the number of variables observed increases very rapidly, their prediction becomes more and more complicated, and the use of all the variables poses problems for classical prediction models.Univariate prediction models are among the first models of prediction. To improve these models, the use of multiple variables has become common. Thus, multivariate models and become more and more used because they consider more information.With the increase of data related to each other, the application of multivariate models is also questionable. Because the use of all existing information does not necessarily lead to the best predictions. Therefore, the challenge in this situation is to find the most relevant factors among all available data relative to a target variable.In this thesis, we study this problem by presenting a detailed analysis of the proposed approaches in the literature. We address the problem of prediction and size reduction of massive data. We also discuss these approaches in the context of Big Data.The proposed approaches show promising and very competitive results compared to well-known algorithms, and lead to an improvement in the accuracy of the predictions on the data used.Then, we present our contributions, and propose a complete methodology for the prediction of wide time series. We also extend this methodology to big data via distributed computing and parallelism with an implementation of the prediction process proposed in the Hadoop / Spark environment

Der volle Inhalt der QuelleTime series prediction is a problem that has been addressed for many years. In this thesis, we have been interested in methods resulting from deep learning. It is well known that if the relationships between the data are temporal, it is difficult to analyze and predict accurately due to non-linear trends and the existence of noise specifically in the financial and electrical series. From this context, we propose a new hybrid noise reduction architecture that models the recursive error series to improve predictions. The learning process fusessimultaneouslyaconvolutionalneuralnetwork(CNN)andarecurrentlongshort-term memory network (LSTM). This model is distinguished by its ability to capture globally a variety of hybrid properties, where it is able to extract local signal features, to learn long-term and non-linear dependencies, and to have a high noise resistance. The second contribution concerns the limitations of the global approaches because of the dynamic switching regimes in the signal. We present a local unsupervised modification with our previous architecture in order to adjust the results by adapting the Hidden Markov Model (HMM). Finally, we were also interested in multi-resolution techniques to improve the performance of the convolutional layers, notably by using the variational mode decomposition method (VMD)

Der volle Inhalt der QuelleTime series are one of the most common types of recorded data in various scientific, industrial, and financial domains. Depending on the context, time series analysis are used for a variety of purposes: forecasting, estimation, classification, and trend and event detection. Thanks to the outstanding capabilities of human visual perception, visualization remains one of the most powerful tools for data analysis, particularly for time series. With the increase in data sets' volume and complexity, new visualization techniques are clearly needed to improve data analysis. They aim to facilitate visual analysis in specified situations, tasks, or for unguided exploratory analysis.Visualization is based upon visual mapping, which consists in association of data values to visual channels, e.g. position, size, and color of the graphical elements. In this regard, the most familiar form of time series visualization, i.e. line charts, consists in a mapping of data values to the vertical position of the line. However, a single visual mapping is not suitable for all situations and analytical objectives.Our goal is to introduce alternatives to the conventional visual mapping and find situations in which, the new approach compensate for the simplicity and familiarity of the existing techniques. We present a review of the existing literature on time series visualization and then, we focus on the existing approaches to visual mapping.Next, we present our contributions. Our first contribution is a systematic study of a "composite" visual mapping which consists in using combinations of visual channels to communicate different facets of a time series. By means of several user studies, we compare our new visual mappings with an existing reference technique and we measure users' speed and accuracy in different analytical tasks. Our results show that the new visual designs lead to analytical performances close to those of the existing techniques without being unnecessarily complex or requiring training. Also, some of the proposed mappings outperform the existing techniques in space constraint situations. Space efficiency is of great importance to simultaneous visualization of large volumes of data or visualization on small screens. Both scenarios are among the current challenges in information visualization

Der volle Inhalt der QuelleThis thesis aims to give a broad coverage of central concepts and principles of causation and in particular the ones involved in the emerging approaches to causal discovery from time series.After reviewing concepts and algorithms, we first present a new approach that infer a summary graph of the causal system underlying the observational time series while relaxing the idealized setting of equal sampling rates and discuss the assumptions underlying its validity. The gist of our proposal lies in the introduction of the causal temporal mutual information measure that can detect the independence and the conditional independence between two time series, and in making an apparent connection between entropy and the probability raising principle that can be used for building new rules for the orientation of the direction of causation. Moreover, through the development of this base method, we propose several extensions, namely to handle hidden confounders, to infer a window causal graph given a summary graph, and to consider sequences instead of time series.Secondly, we focus on the discovery of causal relations from a statistical distribution that is not entirely faithful to the real causal graph and on distinguishing a common cause from an intermediate cause even in the absence of a time indicator. The key aspect of our answer to this problem is the reliance on the additive noise principle to infer a directed supergraph that contains the causal graph. To converge toward the causal graph, we use in a second step a new measure called the temporal causation entropy that prunes for each node of the directed supergraph, the parents that are conditionally independent of their child. Furthermore, we explore complementary extensions of our second base method that involve a pairwise strategy which reduces through multitask learning and a denoising technique, the number of functions that need to be estimated. We perform an extensive experimental comparison of the proposed algorithms on both synthetic and real datasets and demonstrate their promising practical performance: gaining in time complexity while preserving accuracy

Der volle Inhalt der QuelleIn many activity sectors (health, online sales,...) designing from scratch an optimal solution for a defined problem (finding a protocol to increase the cure rate, designing a web page to promote the purchase of one or more products,...) is often very difficult or even impossible. In order to face this difficulty, designers (doctors, web designers, production engineers,...) often work incrementally by successive improvements of an existing solution. However, defining the most relevant changes remains a difficult problem. Therefore, a solution adopted more and more frequently is to compare constructively different alternatives (also called variations) in order to determine the best one by an A/B Test. The idea is to implement these alternatives and compare the results obtained, i.e. the respective rewards obtained by each variation. To identify the optimal variation in the shortest possible time, many test methods use an automated dynamic allocation strategy. Its allocate the tested subjects quickly and automatically to the most efficient variation, through a learning reinforcement algorithms (as one-armed bandit methods). These methods have shown their interest in practice but also limitations, including in particular a latency time (i.e. a delay between the arrival of a subject to be tested and its allocation) too long, a lack of explicitness of choices and the integration of an evolving context describing the subject's behaviour before being tested. The overall objective of this thesis is to propose a understable generic A/B test method allowing a dynamic real-time allocation which take into account the temporals static subjects’s characteristics

Der volle Inhalt der QuelleThis PhD dissertation consists of two parts dealing with the probelms of identification and selection in econometrics. Two mains topics are considered : (1) time series model identification by using (inverse) autocorrelation and (inverse) partial autocorrelation functions ; (2) estimation of inverse autocorrelation function in the framework of nonlinear tima series. The two parts are summarized below. In the first part of this work, we consider time series model identification y using (inverse) autocorrelation and (inverse) partial autocorrelation functions. We construct statistical tests based on estimators of these functions and establish their asymptotic distribution. Using Bahadur and Pitman approaches, we compare the performance of (inverse) autocorelations and (inverse) partial autocorrelations in detecting the order of moving average and autoregressive model. Next, we study the identification of the inverse process of an ARMA model and their probalistic properties. Finally, we characterize the time reversibility by means of the dual and inverse processes. The second part is devoted to estimation of the inverse autocorrelation function in the framework of nonlinear time series. Undes some regularity conditions, we study the asymptotic properties of empirical inverse autocorrelations for stationary and strongly mixing process. We establish the consistency and the asymptotic normality of the estimators. Next, we consider the case of linear process with GARCH errors and obtain means of some examples that the standard formula can be misleading if the generating process is non linear. Finally, we apply our previous results to prove the asymptotic normality of the parameter estimates of weak moving average. Our results are illustrated by Monte Carlo experiments and real data experiences
