Gradient Iterated Temporal-Difference Learning
This paper introduces Gradient Iterated Temporal-Difference (Gi-TD) learning, a novel gradient TD method that overcomes the instability of semi-gradient approaches by computing gradients over moving targets. Gi-TD learning learns a sequence of action-value functions in parallel, aiming to achieve competitive learning speeds against semi-gradient methods, even in complex environments like Atari games where previous gradient TD methods struggled.
Executive Impact
Gi-TD learning offers a robust solution for enhancing agent training stability and speed. By addressing the divergence issues inherent in semi-gradient methods and demonstrating competitive performance across diverse benchmarks, Gi-TD is poised to reduce development cycles and improve the reliability of AI systems for enterprise applications. Its effectiveness in offline reinforcement learning further highlights its potential for leveraging large datasets efficiently.

When combined with DQN, Gi-TD learning (Gi-DQN) significantly outperforms semi-gradient methods across 10 Atari games. Gi-DQN provides a 20% improvement over DQN and a 50 percentage point increase over QRC's AUC. This highlights the competitive learning speed of gradient TD methods in discrete action spaces.
Gi-SAC demonstrates competitive performance against semi-gradient SAC across 6 MuJoCo environments, achieving a 7% improvement in AUC compared to SAC. This indicates Gi-TD's ability to learn informative critics even in complex continuous control tasks.
In offline scenarios, Gi-CQL substantially outperforms other algorithms on 10 Atari games, yielding an AUC that is twice that of CQL. This result emphasizes the benefit of theoretically sound objective functions for efficient data utilization in offline reinforcement learning settings.
