Biography:

Mounîm A. El-Yacoubi obtained a PhD in Signal Processing & Telecommunications from University of Rennes, France, in 1996. During his PhD thesis, he was with the R&D department of the Service de Recherche Technique de la Poste (SRTP) at Nantes, France, then directed by Michel Gilloux, where he developed Handwritten Address Recognition software that is still running in current French mail sorting machines, especially the first French handwritten street name recognition engine. He was a visiting scientist for 18 months at the Centre for Pattern Recognition and Machine Intelligence (CENPARMI) in Montreal, Canada, directed by Prof Ching Y. Suen, where he continued developing address recognition based on Hidden Markov Models. In 1998-2000, he become an associated professor at the Catholic University of Parana (PUC-PR) in Curitiba, Brazil, and was one of the cofounders of a research lab on document analysis in collaboration with CENPARMI and l’Ecole de Technologie Supérieure de Montréal. From 2001 to 2008, he was a Senior Scientist at Parascript, Boulder (CO, USA), a world leader company in automatic document processing, where he developed high-performance software for handwritten and machine print address, check and form recognition, still running today in Automatic reading systems in several countries across the world. Since June 2008, he is a Professor at Telecom SudParis, an engineering school, that is a member of both Institut Mines-Telecom and Paris Saclay University.

Title:

Feature Analysis and Unsupervised Learning

Abstract:

This course aims at giving an overview of two selected topics in Machine Learning which are feature analysis and unsupervised learning. Feature analysis comprises approaches for signal representation and discrimination based on feature space transformations. Classical methods of feature selection and extraction will be reviewed. The part related to Unsupervised learning will stem from approaches related to feature representation and review other techniques such as clustering and mixture models. Some examples of applications in remote sensing will be provided.
Outline:
  • 1. Introduction (signal representation, feature space, supervised/unsupervised learning, etc)
  • 2. Feature Selection (selection criteria and algorithms, measures of dissimilarity, etc)
  • 3. Feature Extraction (linear and non-linear techniques, discriminant analysis, multidimensional scaling, etc)
  • 4. Unsupervised learning (clustering, mixture models, hierarchical approaches, etc)

Title:

End-to-end Speech Recognition with Deep Neural Networks
Basics of Deep Learning for Speech Recognition

Abstract:

This is a three-hour tutorial, during which we will build our way up from the most basic neural network models, and work our way until a complete, simple, end-to-end automatic speech recognition system. Over the course of three hours, we will gradually build up from the simplest multi-layer perceptrons, up to convolutional neural networks, recurrent networks, and sequence-to-sequence transduction systems. We will finally converge to the three main formalisms for the compositions of complete automatic speech recognition systems using neural networks.
The topics to be covered will include:
  • Basics of traditional HMM- and languge-model based speech recognition
  • Basic MLP models and backpropagation for learning
  • Application of MLPs to HMM-based speech recognition
  • A quick intro to convolutional neural networks for feature extraction
  • Recurrent networks and LSTM models
  • CTC models and incorporation into language-model based recognition
  • Attention models
  • Attention-based end-to-end speech recognition.
It is expected that at the end of the lectures students will have a reasonably complete understanding of how state of art systems work.

Title:

Wave propagation, EM interaction and Remote sensing Application to the observation and extraction of parameters of the sea surface

Abstract:

In the context of the observation of the Earth's surface, remote sensing and radar imagery in the general sense make an important contribution in terms of the information collected on the areas and objects observed, and there are many different applications (territorial surveillance, cartography, oceanography, agriculture, glaciology, marine pollution, ...). This type of imaging system makes it possible, among other things, to measure the movement of the ocean surface, including the currents or wakes of ships. However, in order to contribute to the control of a situation above the surface it would be important to combine several aspects (from the sensor through the propagation medium to the processing of signals and / or images). For example, a radio link in the vicinity of the sea surface has its characteristics deeply affected by the presence of the ocean surface. Indeed, the signal from the direct path will be added a number of signals from multiple paths related to reflections from the objects and / or points of the surface. This results in interference between the direct path and the multiple paths resulting in fluctuations in the amplitude and phase of the resulting signal. These fluctuations are a function of the geometry of the link, its electromagnetic characteristics, as well as the state of the sea that depends on the weather conditions. Thus, the control of a situation above the surface is mainly through the characterization and understanding of the electromagnetic phenomena of the environment. And this is reflected directly first by the study of the propagation and interactions of electromagnetic waves with natural environments (atmosphere, rain cloud, sea, soil, forest ...) in the presence of targets or objects. Then by the control of the sensors, the understanding and realistic simulation of the monostatic or bistatic connections (of observation and / or satellites, of perception or communication) placed in this disturbed and evolutionary environment. Finally, the processing and extraction of information from a database of signals (n-D) from different sensors or after transformation constitute one of the last elements of the chain. The objective of this last element is to obtain and merge a greater amount of knowledge and information from the observed scene in order to improve the recognition and automatic identification of targets embedded in a disturbed environment. These different aspects and difficulties will be the subject of the presentation. The illustrations will be based on measurements (generated or real), the works published over several years and made in the context of different partnerships at the same time industrial, university or state.
Keywords: sensors, environment, propagation, wave interaction, radar targets, EM signature, clutter, radar imagery, detection, classification, indexing and image search, reconnaissance, remote sensing, ...

Title:

ILinear Models and Deep Learning for Data Visualization

Abstract:

In Direct Volume Rendering (DVR), the Transfer Function (TF) to map voxel values to color and opacity values is difficult to obtain. Existing TF design tools are complex and non-intuitive for the end user, who is more likely to be a medical professional than an expert in image processing or data modeling. We propose a novel image-centric volume visualization method where the user directly works on the volume data to simply select the parts he/she would like to visualize. The user’s work is further simplified by presenting only the most informative volume slices for selection. Based on the selected parts, all the voxels are classified using our Sparse Nonparametric Support Vector Machine (SN-SVM) classifier and deepl learning methods, which combine both local and near-global distributional information of the training data to obtain accurate results. The voxel classes are then mapped to color and opacity values using the concept of harmonic colors, which provides easily distinguishable and aesthetically pleasing results. The need for visualization emerged from the necessity of informative exploration of data in several domains, such as, medical imaging, seismology, computer network analysis, traffic analysis ans organizational management. For example, in medical visualization, Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scan data shows the visual representation of the patient’s inner organs with an overlay of necessary information (e.g.intensity of the voxels).
