English(EN) When Does Blockwise Additivity Break? Diagnosing and Repairing the Additive Assumption in Distillation-Based Architecture Search

新研究探讨AI架构搜索方法的局限性

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-05 05:46

研究人员发现，在特定延迟预算下，用于架构搜索的块蒸馏方法存在局限性，尤其是在加性假设失效时。研究发现，虽然微调可以缩小性能差距，但尤其是在激进的预算下，仍然存在显著的差异。该论文提出了一些诊断和修复这些故障的方法，包括限制相邻层移除的干预措施以及使用logit-sum预测器对移动进行排序的混合搜索方法，在许多情况下，其性能优于成对交互感知程序。 AI

影响提出改进AI模型架构搜索效率和准确性的方法，有望带来性能更优的模型。

分块可加性何时失效？诊断和修复基于蒸馏的架构搜索中的可加性假设

Blockwise distillation methods for architecture search, such as DNA, DONNA, LANA and Puzzle, score each candidate replacement block in isolation and combine the scores additively. We ask at which budgets this additivity assumption fails, whether fine-tuning repairs the failure, w…
