Early Warning Signals for OpenVLA Failure under Visual Distribution Shift
arXiv:2606.29699v2 Announce Type: replace Abstract: Visual shifts can cause a vision-language-action policy to fail after initially plausible behavior. We ask whether OpenVLA's internal activations contain signals associated with the steps before failure. We freeze the policy, record one MLP activation per LIBERO-10 st
