[hal-01956087] Rapport de Prospective du Conseil Scientifique de l’Institut des Sciences de l’Information et leurs Interactions (INS2I)

La rédaction d’un rapport de prospective scientifique correspond à une des missions des conseils scientifiques d’instituts (CSI) au CNRS. Un tel rapport est à la fois à usage interne au CNRS (directions d'établissement, d’instituts, comité national), et à destination de la communauté scientifique. [...]

[hal-01976660] SPEAKY Project: Adaptive Tutoring System based on Reinforcement Learning for Driving Exercizes and Analysis in ASD Children

Intelligent tutoring systems are increasingly effective for helping the teacher's work with children. However, these technologies are still poorly used for cognitively impaired infants who display autistic spectrum disorders and intellectual disabilities as they don't adapt easily to each infant. [...]

[hal-01926241] Towards perceptual soundscape characterization using event detection algorithms.

Assessing properties about specific sound sources is important to characterize better the perception of urban sound environments. In order to produce perceptually motivated noise maps, we argue that it is possible to consider the data produced by acoustic sensor networks to gather information about sources of interest and predict their perceptual attributes. [...]

[hal-01968962] Unified Low Complexity Radix-2 Architectures for Time and Frequency-domain GFDM Modem

Most of the conventional multicarrier waveforms explicitly or implicitly involve a generalized frequency division multiplexing (GFDM)-based modem as a core part of the baseband processing. Some are based on GFDM with a single prototype filter, e.g. Orthogonal frequency division multiplexing (OFDM) and others employ multiple filters such as filter bank multicarrier (FBMC). [...]

[hal-01930346] Distributed Optimization for Deep Learning with Gossip Exchange

We address the issue of speeding up the training of convolutional neural networks by studying a distributed method adapted to stochastic gradient descent. Our parallel optimization setup uses several threads, each applying individual gradient descents on a local variable. [...]

[hal-01925496] Summarizing Semantic Graphs: A Survey

The explosion in the amount of the available RDF data has lead to the need to explore, query and understand such data sources. Due to the complex structure of RDF graphs and their heterogeneity, the exploration and understanding tasks are significantly harder than in relational databases, where the schema can serve as a first step toward understanding the structure. [...]

[hal-01960235] Fast high-resolution brain metabolite mapping on a clinical 3T MRI by accelerated 1 H-FID-MRSI and low-rank constrained reconstruction

Purpose Epitomizing the advantages of ultra short echo time and no chemical shift displacement error, high-resolution free induction decay magnetic resonance spectroscopic imaging (FID-MRSI) sequences have proven to be highly effective in providing unbiased characterizations of metabolite distributions. [...]

[hal-01958310] State Leakage and Coordination of Actions: Core of the Receiver's Knowledge

We revisit the problems of state masking and state amplification through the lens of empirical coordination by considering a state-dependent channel in which the encoder has causal and strictly causal state knowledge. We show that the problem of empirical coordination provides a natural framework in which to jointly study the problems of reliable communication, state masking, and state amplification. [...]

[hal-01950033] Optimization of Sign-Preserving Noise-Aided Min-Sum Decoders with Density Evolution

The novelty of this paper is to propose a new LDPC decoder called Sign-Preserving Noise-Aided Min-Sum (SP-NA-MS) decoder that improves the decoding performance compared to classical Offset Min-Sum (OMS) decoder when messages are quantized, with only 3 or 4 bits. [...]
