New Policy Gradient Method Tackles Long-Horizon Decision Problems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new approach to address long-horizon decision problems where immediate rewards can lead to detrimental long-term consequences. Their work identifies two key failure modes in policy-gradient methods: 'completion' (reaching the end of the horizon) and 'optimality' (achieving the best possible outcome). By separating these modes, they propose a method that improves completion rates and reduces the optimality gap, demonstrating its effectiveness in simulated environments like a bricklayer career and an NBA player career.

    Completion vs Optimality: Policy Gradient in Long-Horizon Cumulative-Damage Problems

    arXiv:2605.26657v1 Announce Type: new Abstract: Long-horizon decision problems with cumulative damage couple locally attractive actions to globally adverse outcomes. We identify two orthogonal failure modes for policy-gradient methods on this class and propose a decomposition tha…
