In this paper we propose the novel class of hierarchical inverse Q-learning (HIQL) algorithms, which extend the fixed-reward inverse Q-learning (IQL) framework from Kalweit et al. (2020) to solve multiintention IRL problems. We applied HIQL in a real mice decision-making dataset from a dynamic two-armed bandit task (De La Crompe et al., 2023), and mathematically characterized exploitation and exploration behavior of animals during value-based decision-making.
Optophysiology Lab
Our Research
The ability to move is a fundamental feature of most animals which allows them to actively interact with our environment. We are investigating the underlying neural mechanisms and circuits of this ability. We do so with electrophysiological recordings and optogenetic manipulations combined with behavioral analysis. We look into the local processing of movement preparation and generation in the motor cortex as well as higher order structures, e.g. prefrontal cortex.
The goal is to create a better understanding of how neural subpopulations and pathways within and across brain areas influence motor behavior. In order to address these scientific aims we are constantly working on improving the existing techniques. We currently focus on the design of new optoelectronic probes and targeting strategies. Apart from advancing our basic knowledge about the neural mechanisms of movements, our results might help improving the design of new prosthetic devices and understanding of disorders in which the normal production of movements is disrupted.

New Article Published in Neuron
How do brains—biological or artificial—respond and adapt to an ever-changing environment? In a recent meeting, experts from various fields of neuroscience and artificial intelligence met to discuss internal world models in brains and machines, arguing for an interdisciplinary approach to gain deeper insights into the underlying mechanisms.
