Less Data, Better Timing: Student-Curriculum Coupling for VLM On-Policy Distillation in Temporal Video Grounding
Student-Curriculum Coupling (SCC) is a closed-loop framework for post-training vision-language models in temporal video grounding (TVG). It combines a compact Anchor–Frontier curriculum with student-dependent supervision. This means the system dynamically decides which examples to supervise based on the student's current performance, improving accuracy while using significantly fewer training examples and less time.
