Webb8 juni 2024 · Credit assignment is a fundamental problem in reinforcement learning, the problem of measuring an action’s influence on future rewards. Improvements in credit assignment methods have the potential to boost the performance of RL algorithms on many tasks, but thus far have not seen widespread adoption. Webbwork on hindsight (Andrychowicz et al.,2024;Karkus et al.,2016). In that case, it is possible to evaluate a trajectory obtained while trying to achieve an original goal g0for an alternative goal g. Using importance sampling, this information can be exploited using the following central result. Theorem 4.1 (Every-decision hindsight policy gradient). dinner ideas with chicken breast and shrimp

WebbSummary and Contributions: The paper proposes a backward planning model for hindsight credit assignment and analyzed the model on synthetic tasks. Strengths: 1. The paper is well written and easy to follow. 2. It addresses an interesting problem in RL (hindsight credit assignment).
