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. PromptKD (CVPR 2024) established this paradigm with a single PromptSRC-finetuned ViT-L/14 teacher and a ViT-B/16 student. We propose TheProfessor, a multi-teacher extension that distills from a fixed two-teacher ensemble: a domain-finetuned PromptSRC ViT-L/14 teacher and a zero-shot EVA-CLIP-L/14 teacher whose logits are pre-computed per dataset. We evaluate single-teacher Pr

Why this matters
Why now

The continuous drive for more efficient and performant AI models necessitates ongoing research into distillation techniques to reduce computational overhead.

Why it’s important

This development allows for the deployment of more lightweight yet capable vision-language models, expanding their applicability in resource-constrained environments and accelerating model development cycles.

What changes

The ability to distill knowledge from multiple 'teacher' models rather than a single one can lead to student models with improved performance and robustness, making advanced AI capabilities more accessible.
