Apprentissage par renforcement pour les processus décisionnels de Markov partiellement observés Apprendre une extension sélective du passé

We present a new algorithm that extends the Reinforcement Learning framework to Partially Observed Markov Decision Processes (POMDP). The main idea of our method is to build a state extension, called exhaustive observable, which allow us to define a next processus that is Markovian. We bring the proof that solving this new process, to which classical RL methods can be applied, brings an optimal...

Les cahiers du GREYC

We define a simple transform able to map any multi-valued image into a space of patches, such that each existing image patch is mapped into a single high-dimensional point. We show that solving variational problems on this particular space is an elegant way of finding the natural patch-based counterparts of classical image processing techniques, such as the Tikhonov regularization and Lucas-Kan...

Les plaies du tendon patellaire

Les plaies du tendon patellaire sont peu fréquentes et sont peu rapportés dans la littérature, contrairement aux ruptures sous cutanées. Les sections du tendon patellaire nécessitent une réparation immédiate afin de rétablir l'appareil extenseur et de permettre une récupération fonctionnelle précoce. A travers ce travail rétrospectif sur 13 cas, nous analysons les aspects épidémiologiques, thér...

Du papier au numérique - Les archives de l'association Les Restos du Cœœur

The accumulation of records/archives within an association is linked to the growth of the activity in this association. What is to be done when, after sixteen years, the decision is finally taken to preserve the records/archives, as it happened at the “Restos du Cœur”? Besides the legal value stands the historical value, and also the information value for people involved in the activities of th...
