Two Routes to the Middle: Placement Search and Brain Readouts Converge on Where Continual Learners Should Specialize

Continual learners that keep a task-specific adapter in every block of a pre-trained vision transformer accumulate storage linearly with the number of tasks; keeping task-specific adapters in only a few blocks curbs this growth but raises the question of where to place them. We investigate this question from two perspe...

KeyRec: Bounded Visual Memory for Streaming and Long-Video Understanding

Vision-language models are increasingly used to understand long videos and continuous streams. However, dense visual tokens accumulate with video duration, making long-context inference prohibitively expensive. Existing training-free visual-token selection methods reduce this cost by retaining informative tokens, but m...
