Researchers have identified limitations in blockwise distillation methods used for architecture search, particularly when the additivity assumption breaks down under certain latency budgets. The study found that while fine-tuning can reduce performance gaps, significant discrepancies remain, especially at aggressive budgets. The paper proposes methods to diagnose and repair these failures, including interventions that limit adjacent layer removals and a hybrid search approach that uses a logit-sum predictor to rank moves, demonstrating improved performance over pairwise interaction-aware programs in many settings.
