Converts sparse trajectory-level rewards into turn-level credit by aggregating token-level teacher–student log-probability gaps and recursively updating a Bayesian belief in log-odds; produces turn-wise reweighting for policy optimization without an extra critic or rollouts.
Turns a short prompt plus aspect ratio and duration into a structured, shot-by-shot audio-video description for text-to-audio-video generation. A PEFT LoRA on Qwen3.6-27B that expands timing, camera motion, continuity, and synchronized diegetic/non‑diegetic sound; text-only and requires MiniMax-H3 + LightX2V to produce final AV.
