Nonzero effects of intrinsic and extrinsic interfaces

Determine whether the effects of intrinsic interventions and extrinsic continuations are nonzero in learning systems beyond the specific experimental settings examined in the paper.

Background

The paper models intrinsic interventions as constrained changes to the learner’s internal state and extrinsic actions as subsequent training rules acting on the same evolving learner. It emphasizes that these interfaces may affect one another because an intrinsic write changes the state from which external learning proceeds, while external learning changes the states available for later intrinsic intervention.

Although the experiments demonstrate nonzero, continuation-dependent interactions in several specified settings, the general existence of such effects is not established for arbitrary learning systems, interventions, or training continuations. The question therefore concerns whether intrinsic and extrinsic effects are universally or generally nonzero outside the reported cases.

These are architectural possibilities. Whether their effects are nonzero is an empirical question.

The observed effects therefore establish the value of LCT at this model scale, but may not transfer unchanged to larger models, which may be better able to recover from suboptimal segmentation.
