Sun et al.: singular-component expert adaptation with task dispatch

What changed

Learned compact task-specific scales for singular weight components with RL, then dispatched or mixed these expert vectors in a two-pass adaptation process at inference.

Scientific scope

Learned compact task-specific scales for singular weight components with RL, then dispatched or mixed these expert vectors in a two-pass adaptation process at inference. SVD, fine-tuning, expert mixing and task classification are inherited. Tested adaptation is not universal lifelong learning or cross-architecture compatibility; offline expert training and two-pass inference costs remain. Biological analogies are motivation, not an acquired biological result.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. SVD, fine-tuning, expert mixing and task classification are inherited. Tested adaptation is not universal lifelong learning or cross-architecture compatibility; offline expert training and two-pass inference costs remain.
