New Long-Horizon Q-Learning method improves reinforcement learning accuracy

Researchers have introduced Long-Horizon Q-Learning (LQL), a novel method designed to improve the stability of value-based reinforcement learning. LQL addresses the issue of compounding estimation errors in traditional Q-learning by incorporating an inequality-based backstop. This approach penalizes violations of bounds derived from observed action sequences, using existing network outputs to avoid additional computational overhead. Experiments show LQL consistently outperforms standard 1-step and n-step TD learning across various benchmarks. AI
