Texto completo da fonteTime Series Classification (TSC) has received an important amount of interest over the past years due to many real-life applications. In this PhD, we create new algorithms for TSC, with a particular emphasis on Remote Sensing (RS) time series data. We first propose the Dense Bag-of-Temporal-SIFT-Words (D-BoTSW) method that uses dense local features based on SIFT features for 1D data. Extensive experiments exhibit that D-BoTSW significantly outperforms nearly all compared standalone baseline classifiers. Then, we propose an enhancement of the Learning Time Series Shapelets (LTS) algorithm called Adversarially-Built Shapelets (ABS) based on the introduction of adversarial time series during the learning process. Adversarial time series provide an additional regularization benefit for the shapelets and experiments show a performance improvementbetween the baseline and our proposed framework. Due to the lack of available RS time series datasets,we also present and experiment on two remote sensing time series datasets called TiSeLaCand Brazilian-Amazon

Texto completo da fonteFirst, in this dissertation, we will show that Bayesian networks classifiers are very accurate models when compared to other classical machine learning methods. Discretising input variables often increase the performance of Bayesian networks classifiers, as does a feature selection procedure. Different types of Bayesian networks may be used for supervised classification. We combine such approaches together with feature selection and discretisation to show that such a combination gives rise to powerful classifiers. A large choice of data sets from the UCI machine learning repository are used in our experiments, and the application to Epilepsy type prediction based on PET scan data confirms the efficiency of our approach. Second, in this dissertation we also consider modelling interaction between a set of variables in the context of time series and high dimension. We suggest two approaches; the first is similar to the neighbourhood lasso where the lasso model is replaced by Support Vector Machines (SVMs); the second is a restricted Bayesian network for time series. We demonstrate the efficiency of our approaches simulations using linear and nonlinear data set and a mixture of both

Texto completo da fonteAccording to Green-Matignon's version of the conjecture of F. Oort, any series of order pn can be lifted up by a série of the same order which coefficients are integer in a certain extension of Qp. So it is necessary to lift a series of every conjugacy class to lift all formal power series of order pn. That is why, we have studied, in this report, conjugacy classes of formal power series of order pn with coefficients in the algebraic closure Fpalg de Fp. The first chapter is dedicated to recalls on locals fields and especially local fields of characteristc p. In the second chapter, we give a second proof of the theorem of B. Klopsch which states the conjugacy classes of series of order p when the residue field is perfect. The third chapter is dedicated to Witt vectors and gives a reduction of these vectors. Then, in the fourth chapter, we use Witt vectors of length n which, thanks to Artin-Schreier-Witt theory, determined any extensions of degree pn. In the fifth chapter, we use the equivalence between endomorphisms and formal power series to construct the first bijection which states a link between a set An of Witt vectors and a certain characterization of extension of degree pn of K. The second bijection permits, thanks to a certain action of group to get a correspondence between conjugacy classes of order pn and the orbits of An under this action. This is this bijection we will build in the sixth chapter. Finally, in the last chapter, we give two calculations, the first one using the Lubin-Tate theory and the second one Artin-Schreier-Witt theory, to get an explicit writting of series of order 4 for he conjugation law

Texto completo da fonteOur research described in this thesis is about the learning of a motif-based representation from time series to perform automatic classification. Meaningful information in time series can be encoded across time through trends, shapes or subsequences usually with distortions. Approaches have been developed to overcome these issues often paying the price of high computational complexity. Among these techniques, it is worth pointing out distance measures and time series representations. We focus on the representation of the information contained in the time series. We propose a framework to generate a new time series representation to perform classical feature-based classification based on the discovery of discriminant sets of time series subsequences (motifs). This framework proposes to transform a set of time series into a feature space, using subsequences enumerated from the time series, distance measures and aggregation functions. One particular instance of this framework is the well-known shapelet approach. The potential drawback of such an approach is the large number of subsequences to enumerate, inducing a very large feature space and a very high computational complexity. We show that most subsequences in a time series dataset are redundant. Therefore, a random sampling can be used to generate a very small fraction of the exhaustive set of subsequences, preserving the necessary information for classification and thus generating a much smaller feature space compatible with common machine learning algorithms with tractable computations. We also demonstrate that the number of subsequences to draw is not linked to the number of instances in the training set, which guarantees the scalability of the approach. The combination of the latter in the context of our framework enables us to take advantage of advanced techniques (such as multivariate feature selection techniques) to discover richer motif-based time series representations for classification, for example by taking into account the relationships between the subsequences. These theoretical results have been extensively tested on more than one hundred classical benchmarks of the literature with univariate and multivariate time series. Moreover, since this research has been conducted in the context of an industrial research agreement (CIFRE) with Arcelormittal, our work has been applied to the detection of defective steel products based on production line's sensor measurements

Texto completo da fonteThis thesis deals with the development of time series analysis methods. Our contributions focus on two tasks: time series forecasting and classification. Our first contribution presents a method of prediction and completion of multivariate and relational time series. The aim is to be able to simultaneously predict the evolution of a group of time series connected to each other according to a graph, as well as to complete the missing values in these series (which may correspond for example to a failure of a sensor during a given time interval). We propose to use representation learning techniques to forecast the evolution of the series while completing the missing values and taking into account the relationships that may exist between them. Extensions of this model are proposed and described: first in the context of the prediction of heterogeneous time series and then in the case of the prediction of time series with an expressed uncertainty. A prediction model of spatio-temporal series is then proposed, in which the relations between the different series can be expressed more generally, and where these can be learned.Finally, we are interested in the classification of time series. A joint model of metric learning and time-series classification is proposed and an experimental comparison is conducted

Texto completo da fonteThe impact of climat change on the temporal evolution of precipitation as well as the impact of the Parisian heat island on the spatial distribution of précipitation motivate studying the varaibility of the water cycle on a small scale on île-de-france. one way to analyse this varaibility using the data from a rain gauge network is to perform a clustring on time series measured by this network. In this thesis, we have explored two approaches for time series clustring : for the first approach based on the description of series by characteristics, an algorithm for selecting characteristics based on genetic algorithms and topological maps has been proposed. for the second approach based on shape comparaison, a measure of dissimilarity (iterative downscaling time warping) was developed to compare two rainfall time series. Then the limits of the two approaches were discuddes followed by a proposition of a mixed approach that combine the advantages of each approach. The approach was first applied to the evaluation of spatial variability of precipitation on île-de-france. For the evaluation of the temporal variability of the precpitation, a clustring on the precipitation events observed by a station was carried out then extended on the whole rain gauge network. The application on the historical series of Paris-Montsouris (1873-2015) makes it possible to automatically discriminate "remarkable" years from a meteorological point of view

Texto completo da fonteMillions of years of genetic evolution have shaped our auditory system, allowing to discriminate acoustic events in a flexible manner. We can perceptually process multiple de-correlated scales in a multidimensional way. In addition, humans have a natural ability to extract a coherent structure from temporal shapes. We show that emulating these mechanisms in our algorithmic choices, allow to create efficient approaches to perform matching and classification, with a scope beyond musical issues. We introduce the problem of multiobjective Time Series (MOTS) and propose an efficient algorithm to solve it. We introduce two innovative querying paradigms on audio files. We introduce a new classification paradigm based on the hypervolume dominated by different classes called hypervolume-MOTS (HV-MOTS). This system studies the behavior of the whole class by its distribution and spread over the optimization space. We show an improvement over the state of the art methods on a wide range of scientific problems. We present a biometric identification systems based on the sounds produced by heartbeats. This system is able to reach low error rates equivalent to other biometric features. These results are confirmed by the extensive cardiac data set of the Mars500 isolation study. Finally, we study the problem of generating orchestral mixtures that could best imitate a sound target. The search algorithm based on MOTS problem allows to obtain a set of solutions to approximate any audio source

Texto completo da fonteThere are a number of reasons that motivate the interest in computational neuroscience for engineering applications of artificial intelligence. Among them is the speed at which the domain is growing and evolving, promising further capabilities for artificial intelligent systems. In this thesis, a method that exploits the recent advances in computational neuroscience is presented: the liquid state machine. A liquid state machine is a biologically inspired computational model that aims at learning on input stimuli. The model constitutes a promising temporal pattern recognition tool and has shown to perform very well in many applications. In particular, temporal pattern recognition is a problem of interest in military surveillance applications such as automatic target recognition. Until now, most of the liquid state machine implementations for spatiotemporal pattern recognition have remained fairly similar to the original model. From an engineering perspective, a challenge is to adapt liquid state machines to increase their ability for solving practical temporal pattern recognition problems. Solutions are proposed. The first one concentrates on the sampling of the liquid state. In this subject, a method that exploits frequency features of neurons is defined. The combination of different liquid state vectors is also discussed. Secondly, a method for training the liquid is developed. The method implements synaptic spike-timing dependent plasticity to shape the liquid. A new class-conditional approach is proposed, where different networks of neurons are trained exclusively on particular classes of input data. For the suggested liquid sampling methods and the liquid training method, comparative tests were conducted with both simulated and real data sets from different application areas. The tests reveal that the methods outperform the conventional liquid state machine approach. The methods are even more promising in that the results are obtained without optimization of many internal parameters for the different data sets. Finally, measures of the liquid state are investigated for predicting the performance of the liquid state machine.
