Veritas++: Value-aware On-Policy Distillation for Perception-Enhanced AIGI Detection
This work presents Veritas++, a perception-enhanced reasoning framework that establishes reliable perception as the foundation of authenticity reasoning, and introduces Value-aware On-Policy Distillation (VaOPD), an adaptive distillation mechanism that prioritizes high-value distillation signals over uniform supervision, internalizing perception-aware reasoning through a privileged self-teacher.
