Повний текст джерелаIn the field of non-invasive brain imaging, Magnetoencephalography and Electroencephalography (M/EEG) offer invaluable insights into neural activities. The recorded data consist of multivariate time series that provide information about cognitive processes and are often complemented by auxiliary details related to the experimental paradigm, such as timestamps of external stimuli or actions undertaken by the subjects. Additionally, the dataset may include recordings from multiple subjects, facilitating population- level analyses.This doctoral research presents a novel framework for M/EEG signal analysis that synergizes Convolutional Dictionary Learning (CDL) and Temporal Point Processes (TPPs). The work is segmented into two primary components: temporal modeling advancements and computational scalability. For temporal modeling, two novel point process models are introduced with efficient inference methods to capture task-specific neural activities. The proposed Fast Discretized Inference for Hawkes Processes (FaDIn) method also has implications for broader applications. Additionally, this work addresses the computational challenges of large-scale M/EEG data CDL-based analysis, by introducing a novel Stochastic Robust Windowing CDL algorithm. This algorithm allows to process efficiently artifact-ridden signals as well as large population studies. Population CDL was then used on the large open-access dataset Cam-CAN, shedding light on age-related neural activity

Повний текст джерелаConvolutional representations extract recurrent patterns which lead to the discovery of local structures in a set of signals. They are well suited to analyze physiological signals which requires interpretable representations in order to understand the relevant information. Moreover, these representations can be linked to deep learning models, as a way to bring interpretability intheir internal representations. In this disserta tion, we describe recent advances on both computational and theoretical aspects of these models.First, we show that the Singular Spectrum Analysis can be used to compute convolutional representations. This representation is dense and we describe an automatized procedure to improve its interpretability. Also, we propose an asynchronous algorithm, called DICOD, based on greedy coordinate descent, to solve convolutional sparse coding for long signals. Our algorithm has super-linear acceleration.In a second part, we focus on the link between representations and neural networks. An extra training step for deep learning, called post-training, is introduced to boost the performances of the trained network by making sure the last layer is optimal. Then, we study the mechanisms which allow to accelerate sparse coding algorithms with neural networks. We show that it is linked to afactorization of the Gram matrix of the dictionary.Finally, we illustrate the relevance of convolutional representations for physiological signals. Convolutional dictionary learning is used to summarize human walk signals and Singular Spectrum Analysis is used to remove the gaze movement in young infant’s oculometric recordings
Bussy, Victor. "Integration of a priori data to optimise industrial X-ray tomographic reconstruction." Electronic Thesis or Diss., Lyon, INSA, 2024. http://www.theses.fr/2024ISAL0116.
Повний текст джерелаThis thesis explores research topics in the field of industrial non-destructive testing (NDT) using X-rays. The application of CT tomography has significantly expanded, and its use has intensified across many industrial sectors. Due to increasing demands and constraints on inspection processes, CT must continually evolve and adapt. Whether in terms of reconstruction quality or inspection time, X-ray tomography is constantly progressing, particularly in the so-called sparse-view strategy. This strategy involves reconstructing an object using the minimum possible number of radiographic projections while maintaining satisfactory reconstruction quality. This approach reduces acquisition times and associated costs. Sparse-view reconstruction poses a significant challenge as the tomographic problem is ill-conditioned, or, as it is often described, ill-posed. Numerous techniques have been developed to overcome this obstacle, many of which rely on leveraging prior information during the reconstruction process. By exploiting data and knowledge available before the experiment, it is possible to improve reconstruction results despite the reduced number of projections. In our industrial context, for example, the computer-aided design (CAD) model of the object is often available, which provides valuable information about the geometry of the object under study. However, it is important to note that the CAD model only offers an approximate representation of the object. In NDT or metrology, it is precisely the differences between an object and its CAD model that are of interest. Therefore, integrating prior information is complex, as this information is often "approximate" and cannot be used as is. Instead, we propose to judiciously use the geometric information available from the CAD model at each step of the process. We do not propose a single method but rather a methodology for integrating prior geometric information during X-ray tomographic reconstruction

Text is the evolution of humanity after many centuries and the symbol of communication between people. As the image recognition technology matures, the recognition rate of the text in the natural scene is accurate. In many technologies, the deep learning is the best. Convolutional neural network in deep learning has been widely used in text detection and recognition in recent years. However, convolutional neural networks are computationally complex and time-consuming. Our research goals are reduce time-consuming by image preprocessing and word correction by using cloud dictionary. First, searching text areas and significant text priority are used to search visual centers. Visual centers are used to reduce the time-consuming of character recognition with convolution neural networks. The text detection uses MSERs to avoid time-consuming of the sliding window method. Second, the previous people are usually to obtain correct word by searching their own dictionaries. We use cloud dictionary for more efficient recognition and greater fault tolerance.
