Recent usage of sparse-rewards in procedurally-generated environments (PGE) to more adequately measure agent’s generalization capabilities via randomization makes this challenge even harder. Despite some progress of newly created exploration-based algorithms in MiniGrid PGEs, the task remains open for research in terms of improving sample complexity. We contribute to solving this task by creating a new formulation of exploratory intrinsic reward. We base this formulation on a thorough review and categorization of other methods in this area. Agent that optimizes an RL objective with such a formulation performs better than SOTA methods in some small or medium sized PGEs. Додано в НРАТ 2025-05-09 Закрити
