OOD-RL-Bench: A Benchmark Framework for Out-of-Distribution Detection in Reinforcement Learning

Emil Mittag, Richard Dazeley, Peter Vamplew

Reliable reinforcement learning (RL) agents must maintain operational integrity amidst sensor malfunctions, dynamic disturbances, and slow environmental shifts. The detection of out-of-distribution conditions is pivotal to determining when an agent's observations, transitions, or…

Memory Merge DQN: Sensitivity Weighted Target Updates for Stable Value Learning

Adrian Ly, Richard Dazeley, Peter Vamplew, Sunil Aryal, Francisco Cruz

Deep Q-networks use target networks to stabilise bootstrapped value learning, but the standard hard copy update also introduces a tradeoff. Holding the target network fixed, improves short term stability, yet each hard update abruptly replaces the target parameters with the newes…
