*Abstract: * The dynamics of learning in natural and artificial
environments is a problem of great interest to both neuroscientists and
artificial intelligence experts. However, standard analyses of animal
training data either treat behavior as fixed, or track only coarse
performance statistics (e.g., accuracy and bias), providing limited insight
into the dynamic evolution of behavioral strategies over the course of
learning. To overcome these limitations, we propose a dynamic
psychophysical model that efficiently tracks trial-to-trial changes in
behavior over the course of training.  In this talk, I will describe recent
work based on a dynamic logistic regression model that captures the
time-varying  dependencies of behavior on stimuli and other task
covariates, which we applied to mouse training data from the International
Brain Lab (IBL). Secondly, I will discuss efforts to infer animal learning
rules from time-varying behavior in order to characterize how they adjust
their policy in response to reward. Finally, I will describe recent work on
adaptive optimal training, which combines ideas from reinforcement learning
and adaptive experimental design to formulate methods for inferring animal
learning rules from behavior, and using these rules to speed up animal
training.

*About VVTNS : Launched as the World Wide  Theoretical Neuroscience Seminar
(WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in
Memoriam (April 20, 2022), Speakers have the occasion to talk about
theoretical aspects of their work which cannot be discussed in a setting
where the majority of the audience consists of experimentalists. The
seminars, **held on Wednesdays at 11 am ET,**  are 45-50 min long followed
by a discussion. The talks are recorded with authorization of the speaker
and are available to everybody on our YouTube channel.*
