The Professor: Multi-Teacher Unsupervised Prompt Distillation for Vision-Language Models

arXiv:2606. 23897v1 Announce Type: cross Abstract: Prompt distillation compresses large vision-language models (VLMs) such as CLIP into lightweight student models by matching teacher predictions on unlabeled domain images.

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.

Beyond Prompt Count: How Data Shapes Transfer in On-Policy Distillation

The paper investigates how the quantity, source, and selection of prompts influence transfer in on‑policy distillation (OPD) between teacher and student models. It shows that a small set of well‑chosen prompts can achieve performance comparable to large prompt pools, but the effectiveness of prompts depends on the specific teacher‑student pair and target task. The study also finds that prompt utility is relational rather than intrinsic, and that targeted prompt selection does not consistently outperform random sampling.

Zero-Shot Vision-Language Models for Classroom Engagement Recognition: A Benchmark Study of Prompt Sensitivity and Cross-Dataset Generalization

Automated classroom engagement recognition holds substantial promise for scalable learning analytics, yet the suitability of modern Vision-Language Models (VLMs) for this task under zero-shot conditions remains largely unexplored. We present a systematic benchmark that evaluates five widely-used VLMs: CLIP, BLIP-VQA, GPT-4o, LLaVA-1.
