Hybrid classical-quantum computing: are we forgetting the classical part in the binomial?

no code implementations21 Aug 2023 Esther Villar-Rodriguez, Aitor Gomez-Tejedor, Eneko Osaba

The expectations arising from the latest achievements in the quantum computing field are causing that researchers coming from classical artificial intelligence to be fascinated by this new paradigm.

Using Offline Data to Speed-up Reinforcement Learning in Procedurally Generated Environments

no code implementations18 Apr 2023 Alain Andres, Lukas Schäfer, Esther Villar-Rodriguez, Stefano V. Albrecht, Javier Del Ser

Motivated by the recent success of Offline RL and Imitation Learning (IL), we conduct a study to investigate whether agents can leverage offline data in the form of trajectories to improve the sample-efficiency in procedurally generated environments.

Towards Improving Exploration in Self-Imitation Learning using Intrinsic Motivation

1 code implementation30 Nov 2022 Alain Andres, Esther Villar-Rodriguez, Javier Del Ser

Unfortunately, in a broad range of problems the design of a good reward function is not trivial, so in such cases sparse reward signals are instead adopted.
