[hal-02310510] On the Capacity of MIMO Optical Wireless Channels

This paper studies the capacity of a general multiple-input multiple-output (MIMO) free-space optical intensity channel under a per-input-antenna peak-power constraint and a total average-power constraint over all input antennas. The main focus is on the scenario with more transmit than receive antennas. [...]

[hal-02295330] Robot recognizing vowels in a multimodal way

This paper presents a sensory-motor architecture based on a neural network allowing a robot to recognize vowels in a multi-modal way thanks to human mimicking. The robot autonomously learns to associate its internal state to a human's vowel as an infant would to recognize vowel, and learn to associate congruent information. [...]

[hal-02314572] Towards a Semantic Indoor Trajectory Model

In this paper we present a Semantic Indoor Trajectory Model aimed at supporting the design and implementation of context-aware mobility data mining and statistical analytics methods. Motivated by a compelling museum case study, and by what we perceive as a lack in indoor trajectory research, we are interested in combining aspects of state-of-the art semantic outdoor trajec-tory models, with a semantically-enabled hierarchical symbolic representation of the indoor space, which abides by OGC's In-doorGML standard. [...]

[hal-02309379] Gated spiking neural network using Iterative Free-Energy Optimization and rank-order coding for structure learning in memory sequences (INFERNO GATE)

We present a framework based on iterative free-energy optimization with spiking neural networks for modeling the fronto-striatal system (PFC-BG) for the generation and recall of audio memory sequences. In line with neuroimaging studies carried out in the PFC, we propose a genuine coding strategy using the gain-modulation mechanism to represent abstract sequences based solely on the rank and location of items within them. [...]

[hal-02314445] Human pose regression by combining indirect part detection and contextual information

In this paper, we tackle the problem of human pose estimation from still images, which is a very active topic, specially due to its several applications, from image annotation to human-machine interface. We use the soft-argmax function to convert feature maps directly to body joint coordinates, resulting in a fully differentiable framework. [...]

[halshs-02275550] Political language patterns’ dissemination between a political leader and his campaign community: a CMC corpora analysis

[hal-02309147] Metric Learning with HORDE: High-Order Regularizer for Deep Embeddings

Learning an effective similarity metric between the image representations is key to the success of the recent advances in visual search tasks (e.g. verification or zero shot learning). Although the metric learning part is well addressed, this metric is usually computed over the average of the extracted deep features. [...]

[hal-02278196] Jeu d'estimation de l'état de canal et coordination

Nous étudions le problème du masquage et de l'amplification de l'état d'un canal en utilisant les outils de la coordination empirique. L'encodeur observe l'état du canal de manière causale et met en oeuvre un schéma de codage afin de contrôler la divulgation de l'état du canal tout en transmettant un débit d'information. [...]

[hal-01633656] Persuasion with limited communication capacity

We consider a Bayesian persuasion problem where the persuader and the decision maker communicate through an imperfect channel which has a fixed and limited number of messages and is subject to exogenous noise. Imperfect communication entails a loss of payoff for the persuader. [...]
