Feature Extraction for Effective and Efficient Deep Reinforcement Learning on Real Robotic Platforms

ICRA 2023poster

Deep reinforcement learning (DRL) methods can solve complex continuous control tasks in simulated environments by taking actions based solely on state observations at each decision point. Because of the dynamics involved, individual snapshots of real-world sensor measurements afford only partial sta…

Non-blocking Asynchronous Training for Reinforcement Learning in Real-World Environments

IROS 2022poster

Deep Reinforcement Learning (DRL) faces challenges bridging the sim-to-real gap to enable real-world applications. In contrast to the simulated environments used in conventional DRL training, real-world systems are non-linear and evolve in an asynchronous fashion; sensors and actuators have limited…

Approximating the Shapley Value Using Stratified Empirical Bernstein Sampling

IJCAI 2021poster

The Shapley value is a well recognised method for dividing the value of joint effort in cooperative games. However, computing the Shapley value is known to be computationally hard, so stratified sample-based estimation is sometimes used. For this task, we provide two contributions to the state of th…
