Enhanced Knowledge Distillation for Detection Transformer via Teacher Prediction Refinement

The paper introduces Teacher Prediction Refinement Distillation (TPRD), a plug‑in module for Detection Transformers that refines teacher predictions before distillation. TPRD corrects degraded positive predictions and suppresses overconfident negatives, while preserving informative dark knowledge through Maximum Dark Knowledge Preservation. Experiments on MS COCO and PASCAL VOC show that these refinements improve the quality of supervision and the resulting student model’s performance.

Rethinking Classifier-Free Guidance in On-Policy Diffusion Distillation

arXiv:2607. 24731v1 Announce Type: cross Abstract: On-policy distillation (OPD) adapts diffusion models by querying a teacher along trajectories generated by the current student, but how it should behave under classifier-free guidance (CFG), a default component of modern diffusion systems, remains poorly understood.

CA-OPD: Confidence-Aware On-Policy Distillation for Structured Visual Prediction

CA-OPD is a confidence‑aware on‑policy distillation framework that improves structured visual prediction by using teacher confidence to selectively correct unreliable student transitions and gradually transfer rollout control to the student. The method aligns supervision with intervention decisions, providing direct cross‑entropy loss for corrected tokens and full predictive distribution for retained tokens. In a multi‑teacher setting for GUI grounding and OCR, CA‑OPD significantly outperforms the Qwen3.5‑0.8B baseline, achieving large gains on benchmarks such as ScreenSpot‑Pro and OCRBench‑v2 English.

Persistent Negatives for Adversarial Black-Box On-Policy Distillation

The paper introduces Persistent Negative Adversarial Distillation, a method that improves black-box on-policy distillation by maintaining a live pool of historical teacher–student comparisons to stabilize the discriminator’s negative distribution. By anchoring the discriminator with these persistent negatives, the approach reduces reward-estimation error and yields smoother, higher-performing student policies across multiple benchmarks. The study demonstrates that the choice of negative samples is a critical design factor in effective black-box distillation.

Grid-Preserving Knowledge Distillation: Transferring Convolutional Inductive Bias to Vision Transformers under Data Scarcity

Vision Transformers underperform convolutional networks when training data is scarce, and distilling convolutional inductive biases from a CNN teacher is an effective remedy that leaves the deployed model unchanged. General-purpose feature distillation, however, transfers little in this setting.
