New research paper identifies policy necrosis and redundant coverage in Option-Critic algorithms

By PulseAugur Editorial · [1 sources] ·

A new research paper published on arXiv explores the limitations of the Option-Critic algorithm in reinforcement learning. The study identifies two key issues: policy necrosis, where an option's internal policy becomes stuck and stops exploring, and redundant coverage, where adding more options does not improve performance but rather reduces the chance of all options failing simultaneously. The researchers propose solutions including forcing termination at every step and restoring exploration to mitigate these problems. AI

    When Do Options Help? Policy Necrosis and Redundant Coverage in Option-Critic

    arXiv:2609.05508v1 Announce Type: cross Abstract: Option-critic learns options: sub-policies together with a learned rule for when each one hands control back. Its headline result is that performance improves as options are added. We explain that result, with theory and experimen…
