Deep Bayesian Experimental Design for Quantum Many-Body Systems

1 code implementation26 Jun 2023 Leopoldo Sarra, Florian Marquardt

Bayesian experimental design is a technique that allows to efficiently select measurements to characterize a physical system by maximizing the expected information gain.

Unlocking the Power of Representations in Long-term Novelty-based Exploration

no code implementations2 May 2023 Alaa Saade, Steven Kapturowski, Daniele Calandriello, Charles Blundell, Pablo Sprechmann, Leopoldo Sarra, Oliver Groth, Michal Valko, Bilal Piot

We introduce Robust Exploration via Clustering-based Online Density Estimation (RECODE), a non-parametric method for novelty-based exploration that estimates visitation counts for clusters of states based on their similarity in a chosen embedding space.

Renormalized Mutual Information for Artificial Scientific Discovery

1 code implementation4 May 2020 Leopoldo Sarra, Andrea Aiello, Florian Marquardt

We derive a well-defined renormalized version of mutual information that allows to estimate the dependence between continuous random variables in the important case when one is deterministically dependent on the other.
