MEET: A Monte Carlo Exploration-Exploitation Trade-Off for Buffer Sampling

ICASSP 2023accepted

Data selection is essential for any data-based optimization technique, such as Reinforcement Learning. State-of-the-art sampling strategies for the experience replay buffer improve the performance of the Reinforcement Learning agent. However, they do not incorporate uncertainty in the Q-Value estima…

RUDDER: Return Decomposition for Delayed Rewards

NeurIPS 2019poster

We propose RUDDER, a novel reinforcement learning approach for delayed rewards in finite Markov decision processes (MDPs). In MDPs the Q-values are equal to the expected immediate reward plus the expected future rewards. The latter are related to bias problems in temporal difference (TD) learning an…
