Researchers at the University of Padua have introduced Aftab, a novel CNN architecture that significantly enhances off-policy reinforcement learning by eliminating the need for large replay buffers. By optimizing encoder design and incorporating Hadamax encoding, this approach achieves an 86% higher probability of success on Atari-57 benchmarks while maintaining memory efficiency and robust out-of-distribution generalization.
Aftab Improves Reinforcement Learning with 86% Greater Probability of Success

Aftab improves deep Q-Network performance, achieving an 86% greater probability of success on the Atari-57 benchmark through novel CNN architecture and Hadamax encoding. This advances off-policy learning without large replay buffers.
Researchers at University of Padua and colleagues present a comprehensive analysis of Convolutional Neural Network encoders within Parallelized Q-Networks, addressing a key gap in efficient reinforcement learning. Their work systematically evaluates eight distinct CNN architectures, optimising for performance under strict parameter limitations and exploring advanced value function enhancements like Hadamax encoding, distributional, ensemble, and dueling heads. Extensive testing on the Atari-57 benchmark reveals that their proposed composite architecture, Aftab, achieves an Interquartile Mean Human-Normalized Score of…
