EvoPrompt: Guided Prompt Evolution for Vision-Language Models Adaptation

arXiv:2603.09493v2 Announce Type: replace-cross Abstract: The adaptation of large-scale vision-language models (VLMs) to downstream tasks with limited labeled data remains a significant challenge. While parameter-efficient prompt learning methods offer a promising path, they often suffer from catastrophic forgetting of pre-trained knowledge. Toward addressing this limitation, our work is grounded in the insight that governing the evolutionary path of prompts is essential for forgetting-free adaptation. To this end, we propose EvoPrompt, a novel framework designed to explicitly steer the prompt

Why this matters
Why now

The paper addresses a current fundamental challenge in adapting large vision-language models efficiently without sacrificing pre-existing knowledge, a critical area in active AI development.

Why it’s important

Improving prompt learning for VLMs unlocks more efficient deployment of powerful AI, crucial for widespread adoption and task-specific applications with limited data.

What changes

This framework offers a method to evolve prompts in a 'forgetting-free' manner, potentially making VLM adaptation more robust and less resource-intensive.
