Interference-Gated Dynamic Activation for Task-Agnostic Continual Learning: A Formal-Empirical Audit of Stability, Forgetting, and Failure Regimes
Continual learning methods frequently reduce forgetting by adding replay, regularization, or routing constraints, yet activation functions are usually treated as fixed nonlinearities rather than adaptive components of the retention mechanism. We study a task-agnostic setting where task identities are unavailable and dynamic activation updates must operate…Read more

Contribution-and-evidence summary: The manuscript delivers a hybrid formal-empirical audit of interference-gated dynamic activation for task-agnostic continual learning, with executed benchmark artifacts, symbolic checks, negative-result reporting, and explicit claim-scope controls; evidence supports an auditable mixed-result paper rather than a positive-performance paper. Substantive strengths: comparator fairness controls are explicit and enforced, formal assumptions and applicability limits are stated in main text, empirical reporting includes uncertainty/ablation/failure-regime evidence, and figure/table integration is publication-ready with vector graphics and in-text references. Substantive weaknesses: forgetting-improvement evidence for the core mechanism remains mixed (dynamic full is largely parity with static GELU in the executed matrix), one projection-bound symbolic simplification path fails and limits formal confidence, and CORe50 remains descriptor-only so cross-substrate generalization breadth is not yet closed. Real open questions: whether stronger interference windows or replay-policy coupling can produce robust positive Delta_F under matched fairness constraints, and whether a repaired projection-bound argument can remain valid under the empirically relevant regimes. High-leverage improvements: execute one matched CORe50-inclusive rerun (or equivalent declared replacement with strict scope language), pre-register mechanism-sensitive sweeps tied to alignment windows, and either repair or further narrow the failed symbolic path with explicit theorem-to-limit wording. Minor polish: keep dataset-substrate scope wording uniform between abstract/results/limitations and keep theorem-audit caveat language tightly synchronized across formal analysis and conclusion.
- Hybrid modality fit is strong for the user intent: the manuscript combines algorithm/pseudocode, formal statements with assumptions, and executed benchmark evidence rather than forcing a purely theorem-only or purely shallow empirical framing. - Claim-evidence traceability is high: main claims are connected to concrete tables/figures and appendix diagnostics, including explicit negative outcomes and caveats. - Comparator fairness and reproducibility controls are well specified (matched replay/optimizer/schedule/memory accounting) and integrated into interpretation, reducing attribution confounds. - Manuscript quality checks passed for conference style, vector figure usage, caption presence, in-text figure/table references, and main-body page budget before references/appendix.
- Affected claim: hm-claim-1 (forgetting improvement). Missing/contradictory evidence: executed reduced matrix shows near-parity between dynamic full and static GELU with mixed support, so robust positive forgetting improvement is not established. Owning phase: validation_simulation (evidence generation) with writing_presentation/revision (scope framing). Acceptance condition: either produce matched-fairness runs with positive Delta_F and uncertainty support on primary substrate(s), or keep the contribution framed explicitly as a negative/mixed audit outcome across title/abstract/introduction/conclusion. - Affected claim: dmm-claim-1 formal confidence. Missing/contradictory evidence: theorem audit includes a failed projection-bound simplification path, limiting formal closure to local conditional diagnostics. Owning phase: derive_math_methodology with revision integration. Acceptance condition: repair the failed symbolic path with corrected assumptions/derivation and successful audit rerun, or explicitly keep theorem scope non-guarantee and limitations-bounded everywhere claim-facing. - Affected claim: cross-substrate generalization breadth. Missing evidence: CORe50 remains descriptor-only in this iteration, with fallback dataset used for executed third-substrate coverage. Owning phase: validation_simulation with writing_presentation/revision. Acceptance condition: execute CORe50 results-visible runs under matched controls, or keep generalization language restricted to executed substrates with explicit non-equivalence statement.
- Under what measurable alignment-window regimes (strength, persistence, and gate contrast) can interference-gated activation move from parity to reliably positive forgetting deltas without fairness violations? - Can replay-policy and activation-state updates be co-designed so that mechanism attribution remains clean while improving retention beyond static GELU in task-agnostic streams? - What minimal additional assumptions are sufficient to repair the projection-bound formal path without introducing unrealistic smoothness or regime constraints?
- Run one targeted CORe50-inclusive benchmark pass with the same seeds/comparator fairness predicates, and report claim status transition rules before execution. - Add a mechanism-sensitive sweep focused on alignment-window diagnostics (not just global averages) and tie each sweep axis to explicit acceptance/refutation criteria. - Perform a formal patch cycle on the failed projection simplification: restate assumptions, re-run symbolic checks, and update theorem text and appendix matrix in lockstep.
