Fisher Rank Inflation: Memorization Signature in Noisy Deep Learning

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员发现了一种称为 Fisher Rank Inflation 的现象，它作为在标签噪声下训练的深度学习模型中记忆的谱特征。当模型从学习干净数据结构过渡到记忆损坏标签时，会发生这种膨胀，导致每例最后一层梯度的有效秩扩大然后收缩。该研究在各种数据集和模型架构中展示了这种效应，显示标签噪声的严重程度与 Fisher 有效秩的增加之间存在相关性，这可能先于可观察到的测试性能下降。 AI

影响 识别出一种新的谱特征，有助于诊断和缓解噪声数据集中的记忆问题，可能提高模型的鲁棒性。

    Fisher Rank Inflation: A Spectral Signature of Memorization under Label Noise

    Deep networks trained with label noise often learn clean structure before memorizing corrupted labels. We show that this transition leaves a spectral signature in the centered scatter of per-example last-layer gradients. Its effective rank transiently expands during memorization …
