Question-Guided Token Pruning Proposed as Privacy Defense for Vision-Language Models
A new arXiv paper proposes pruning visual tokens based on the question being asked, rather than sending all visual features to the server in split-learning setups. The approach targets vision-language question answering in federated, split, and U-shaped split learning, where raw data stays local but transmitted representations can still leak information. The authors frame selective transmission as a way to reduce both privacy exposure and bandwidth use.
