Self-improving policies expose new failure patterns, which changes what their judges must verify, and fixed judges limit the feedback they get.

Slide 1 of 9. The judge needs training too VeriFine updates the policy, the curriculum and the judge together. (Figure: Zhou, Zewei et al., arXiv:2610.08761, CC BY 4.0)

Slide 2 of 9. Meme: Me when the AI grader I trusted to check my AI's homework turns out to need homework too Picture (AI-generated): A robot grader sits at a school desk doing homework while a weary engineer with coffee looks on.

Slide 3 of 9. Fixed judges limit feedback Self-improving policies expose new failure patterns, which changes what their judges must be able to verify. Fixed judges limit the feedback they get.

Slide 4 of 9. Three parts improve together VeriFine, from Zewei Zhou and colleagues, improves the policy, curriculum and judge together instead of treating the judge as fixed.

Slide 5 of 9. Policy loop: diagnose, then train A rubric judge diagnoses recurring failures. VeriFine uses them to build an adaptive curriculum, then optimizes the policy.

Slide 6 of 9. Judge loop: humans step in When progress plateaus and verification becomes a bottleneck, VeriFine selectively queries human guidance on informative failure cases.

Slide 7 of 9. Tested on driving and navigation Experiments cover driving and robot navigation, across reinforcement and supervised fine-tuning.

Self-improving policies expose new failure patterns, which changes what their judges must verify, and fixed judges limit the feedback they get. VeriFine, from Zewei Zhou and colleagues, updates the judge alongside the policy and the training curriculum. When progress stalls, it asks humans for guidance on informative failure cases. The experiments cover driving and robot navigation.
