An
introduction on Reinforcement Learning and Deep RL
This presentation is meant
to provide basics of Reinforcement Learning (RL) and introduce
Deep Reinforcement Learning (DRL), for both synthetic and more
realistic problems. While applications of RL are typically limited
to discrete, lowdimensional constraints, recent advances in Deep
RL (
DQN for Atari 2600,
AlphaGo, and more
lately
AlphaGo Zero) have
demonstrated humanlevel or superhuman performance in complex,
highdimensional spaces. However, DRL remains an active research
domain and, as often experienced, is not yet a plugandplay
optimization tool. In this presentation, we will also peek into
this challenging aspect of DRL for general control problems such
as a robot navigation task, discussing difficulties inherent to RL
and most recent approaches to such problems.

An introduction to the
mathematical proofs of reinforcement learning
Numerous reinforcement learning algorithms have been introduced
these last few years to efficiently solve an increasing vast array
of problems. Despite their variety, most of them rely on a few
welltrodden ideas, the main difficulty being to adapt these ideas
to a specific situation. The goal of this presentation is to give
the mathematical tools to understand two fundamental and easily
generalizable toymodels of reinforcement learning: the stochastic
bandits and adversarial bandits.

Neural basis of learning
Human beings are born with the fascination gift of learning.
With aid of such, they absorb and assimilate knowledge
throughout thier entire life. Reinforcement Learning (RL) is
one of the computational methods that attempt to simulate such
characteristic in a computational environment capable of
learning. However, RL carries different meanings for different
communities from mathematics, computer science, neuroscience
to psychology, etc. In this talk, I will try to clarify in
general the similarities of RL in different
domains and in which ways they differ with a focus on
the neurocognitive part of the brain to understand the
mechanisms behind human/animal learning and decisionmaking
