Policy Optimization via Importance Sampling

Metelli, Alberto Maria, Papini, Matteo, Faccio, Francesco et al.

Understand

Policy optimization is an effective reinforcement learning approach to solve continuous control tasks.

  • Recent achievements have shown that alternating online and offline optimization is a successful choice for efficient trajectory reuse.
  • However, deciding when to stop optimizing and collect new trajectories is non-trivial, as it requires to account for the variance of the objective function estimate.
  • In this paper, we propose a novel, model-free, policy search algorithm, POIS, applicable in both action-based and parameter-based settings.
