Attribution of Delayed Cross-Modal Feedback
Determine how to assign delayed and cross-modal feedback to the earlier multimodal memory-writing, maintenance, or retrieval decisions that caused an outcome, while separating those effects from intervening operations.
Background
Feedback for retrieval is often relatively direct, but the effects of writing, merging, revision, or forgetting may become visible much later and through a different modality. For example, a visual memory may be shown to be incorrect by a later instruction or by an action failure.
Self-improving memory management therefore requires credit assignment across time, modalities, and multiple intervening memory operations. The paper identifies this attribution problem as a barrier to extending policy evolution beyond retrieval.
References
What remains open is how to assign delayed and cross-modal feedback to earlier memory decisions while separating their effects from the many other operations that occur in between.
