Accord ou invariabilité du participe passé : les règles problématiques

Usages prescrits ou annoncés, usages observés. Réflexions sur les usages scolaires du numérique par les enseignants

The use of ICT for Education is an extremely complex issue that can and should be analyzed from different perspectives. This article does not intend to cover all of them but, instead, try to address only some of them by developing a high level view showing the contradictions that characterize different official statements and stressing some educational paradoxes. The article describes the Frenc...

SUSY Les Houches Accord 2

The Supersymmetry Les Houches Accord (SLHA) [1] provides a universal set of conventions for conveying spectral and decay information for supersymmetry analysis problems in high energy physics. Here, we propose extensions of the conventions of the first SLHA to include various generalisations: the minimal supersymmetric standard model with violation of CP, R-parity, and flavour, as well as the s...

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...
