神经网络插值揭示了短暂的准确性峰值现象

研究人员在神经网络中发现了一种称为BUMP(短暂意外插值中期峰值)的现象,其中测试准确性在插值终点附近会暂时提高,然后下降。这种效应已在各种数据集、架构和训练方法中观察到,并且对早期检查点和极端剪枝等显著扰动具有鲁棒性。研究人员提出了一种新颖的集成方法——权重预测混合集成,该方法将权重混合与预测空间混合相结合。该方法在测试准确性方面始终优于标准的logit集成,并提供了改进的校准,证明了在权重和预测空间中混合的互补优势。 AI

影响 识别出神经网络插值中的一种新颖现象,可能带来改进的集成技术。

    BUMP:简短意外的中间插值峰值

    arXiv:2611.08182v1 Announce Type: cross Abstract: We identify an intriguing phenomenon when linearly interpolating between permutation-aligned neural networks: test accuracy briefly improves near the interpolation endpoints before dropping toward the midpoint, which we term BUMP …
