新统计方法在分类准确性上优于QDA和GAM

作者 PulseAugur 编辑部 · [2 个来源] ·

一篇新研究论文介绍了一种用于椭圆马氏判别分析的闭式分数径向链接，旨在提高二元分类准确性。所提出的方法推导了一个贝叶斯径向链接族，并使用分数幂随机多项式投影进行估计，为样条调优提供了一种替代方案。该方法在包括金融数据和乳腺癌等医学数据集在内的各种基准测试中，已证明与QDA和全局GAM等现有方法相比，具有竞争力或更优越的性能。 AI

影响 引入了一种新颖的统计技术，可以提高机器学习模型的分类准确性。

    椭圆马氏判别分析的闭式分数径向链接

    We study binary classification under shared-generator elliptical class-conditional distributions. The log-likelihood ratio is an additive function of the two squared Mahalanobis radii, with radial link $\varphi=\log g$; QDA is recovered only when this link is affine. We derive th…
