English(EN) MahaVar: OOD Detection via Class-wise Mahalanobis Distance Variance under Neural Collapse

MahaVar 利用类内马氏距离方差改进OOD检测

研究人员推出了一种新颖的深度神经网络中分布外(OOD)样本检测方法MahaVar。该技术利用了一个经验观察,即分布内样本的类内马氏距离方差高于OOD样本。这一观察在理论上基于神经坍塌(Neural Collapse)的原理,该原理与类内紧凑性和类间分离有关。MahaVar将标准的马氏距离与此类内方差项相结合,在CIFAR-100和ImageNet等基准测试中取得了最先进的性能。 AI

影响 通过改进分布外检测,提高了深度神经网络在安全关键应用中的可靠性。

    MahaVar:神经崩溃下基于类间马氏距离方差的OOD检测

    arXiv:2605.14413v2 Announce Type: replace-cross Abstract: Out-of-distribution (OOD) detection is a critical component for ensuring the reliability of deep neural networks in safety-critical applications. In this work, we present a key empirical observation: for in-distribution (I…
