| contents | Reinforcement learning (RL) algorithms often struggle in environments with sparse rewards, leading to inefficient exploration and prolonged training times. This paper investigates the integration of intrinsic curiosity modules (ICM) with reward shaping techniques to mitigate these challenges. We propose a novel approach that combines ICM-generated intrinsic rewards with carefully designed extrinsic reward shaping functions to guide the agent's exploration and accelerate learning. Our experiments demonstrate the effectiveness of this combined approach in benchmark sparse reward environments, achieving significant improvements in sample efficiency and overall performance compared to traditional RL methods and ICM-only implementations. |
