Learning Object-Centered Autotelic Behaviors with Graph Neural Networks [article]

Ahmed Akakzia, Olivier Sigaud
2022 arXiv   pre-print
In this paper, we propose to investigate the impact of these representations on the learning capabilities of autotelic agents.  ...  Although humans live in an open-ended world and endlessly face new challenges, they do not have to learn from scratch each time they face the next one.  ...  At test time, the per-class performance of the agent is computed on 24 goals of each evaluation class (264 semantic goals and 120 continuous goals).  ...
