新多类别分类目标在噪声下的性能评估

研究人员开发并评估了三个新颖的多类别分类目标:一个类别感知的二次Bregman得分(CAPM)、一个具有约束log-cosh脊的强凸生成器(HPG),以及一个具有退火概率边际惩罚(APMS)的HPG目标。该研究提供了理论分析,包括CAPM和HPG的条件遗憾和曲率界,以及APMS的精确惩罚范围界。在Digits和Wisconsin乳腺癌等数据集上,在各种噪声和不平衡条件下进行的经验评估表明,这些方法在干净数据上的性能与交叉熵相当,并在某些噪声标签场景中显示出边际收益,尽管未确立普遍的优越性。 AI

影响 引入了可能提高分类在噪声环境中鲁棒性的新颖损失函数。

    多类别分类的结构化损失几何:理论与受控经验评估

    arXiv:2606.29471v1 Announce Type: new Abstract: Strictly proper scoring rules identify the true conditional class distribution at population level, but their curvature can alter optimization and finite-sample behavior. We study three multiclass objectives: a class-aware quadratic…
