Dynamic Facial Expression Recognition under Partial Occlusion with Optical Flow Reconstruction
Delphine Poux, Benjamin Allaert, Nacim Ihaddadene +3
Video facial expression recognition is useful for many applications and received much interest lately. Although some solutions give really good results in a controlled environment…
Group design in group testing for COVID-19 : A French case-study
Tifaout Almeftah, Luce Brotcorne, Diego Cattaruzza +5
Group testing is a screening strategy that involves dividing a population into several disjointed groups of subjects. In its simplest implementation, each group is tested with a si…
Extending Equational Monadic Reasoning with Monad Transformers
Reynald Affeldt, David Nowak
There is a recent interest for the verification of monadic programs using proof assistants. This line of research raises the question of the integration of monad transformers, a st…
Sub-sampling for Efficient Non-Parametric Bandit Exploration
Dorian Baudry, Emilie Kaufmann, Odalric-Ambrym Maillard
In this paper we propose the first multi-armed bandit algorithm based on re-sampling that achieves asymptotically optimal regret simultaneously for different families of arms (name…
Learning Value Functions in Deep Policy Gradients using Residual Variance
Yannis Flet-Berliac, Reda Ouhamma, Odalric-Ambrym Maillard +1
Policy gradient algorithms have proven to be successful in diverse decision making and control tasks. However, these methods suffer from high sample complexity and instability issu…
Improved Exploration in Factored Average-Reward MDPs
Mohammad Sadegh Talebi, Anders Jonsson, Odalric-Ambrym Maillard
We consider a regret minimization task under the average-reward criterion in an unknown Factored Markov Decision Process (FMDP). More specifically, we consider an FMDP where the st…
Quantitative inference of the column densities from 3 mm molecular emission: A case study towards Orion B
Pierre Gratier, Jérôme Pety, Emeric Bron +21
Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or…
Channel Estimation for Intelligent Reflecting Surface Assisted MIMO Systems: A Tensor Modeling Approach
Gilderlan T. de Araújo, André L. F. de Almeida, Rémy Boyer
Intelligent reflecting surface (IRS) is an emerging technology for future wireless communications including 5G and especially 6G. It consists of a large 2D array of (semi-)passive…
Tracers of the ionization fraction in dense and translucent gas: I. Automated exploitation of massive astrochemical model grids
Emeric Bron, Evelyne Roueff, Maryvonne Gerin +21
The ionization fraction plays a key role in the physics and chemistry of the neutral interstellar medium, from controlling the coupling of the gas to the magnetic field to allowing…
Equivalence-Invariant Algebraic Provenance for Hyperplane Update Queries
Pierre Bourhis, Daniel Deutch, Yuval Moskovitch
The algebraic approach for provenance tracking, originating in the semiring model of Green et. al, has proven useful as an abstract way of handling metadata. Commutative Semirings…
Learning from DPPs via Sampling: Beyond HKPV and symmetry
Rémi Bardenet, Subhroshekhar Ghosh
Determinantal point processes (DPPs) have become a significant tool for recommendation systems, feature selection, or summary extraction, harnessing the intrinsic ability of these…
A note on the class of languages generated by F-systems over regular languages
Jorge C. Lucero, Sławek Staworko
An F-system is a computational model that performs a folding operation on words of a given language, following directions coded on words of another given language. This paper consi…
Non-monotone target sets for threshold values restricted to , , and the vertex degree
Julien Baste, Stefan Ehard, Dieter Rautenbach
We consider a non-monotone activation process on a graph , where , for ever…
Planning in Markov Decision Processes with Gap-Dependent Sample Complexity
Anders Jonsson, Emilie Kaufmann, Pierre Ménard +3
We propose MDP-GapE, a new trajectory-based Monte-Carlo Tree Search algorithm for planning in a Markov Decision Process in which transitions have a finite support. We prove an uppe…
Modeling Baroque Two-Part Counterpoint with Neural Machine Translation
Eric P. Nichols, Stefano Kalonaris, Gianluca Micchi +1
We propose a system for contrapuntal music generation based on a Neural Machine Translation (NMT) paradigm. We consider Baroque counterpoint and are interested in modeling the inte…
Disentangled Representation Learning and Generation with Manifold Optimization
Arun Pandey, Michael Fanuel, Joachim Schreurs +1
Disentanglement is a useful property in representation learning which increases the interpretability of generative models such as Variational autoencoders (VAE), Generative Adversa…
C18O, 13CO, and 12CO abundances and excitation temperatures in the Orion B molecular cloud: An analysis of the precision achievable when modeling spectral line within the Local Thermodynamic Equilibrium approximation
Antoine Roueff, Maryvonne Gerin, Pierre Gratier +23
CO isotopologue transitions are routinely observed in molecular clouds to probe the column density of the gas, the elemental ratios of carbon and oxygen, and to trace the kinematic…
