机器学习中高斯核的使用因预测不确定性和条件化问题受到质疑

一篇新论文反对在高斯核(也称为平方指数核或径向基函数核)在机器学习任务(如回归和分类)中的广泛使用。作者认为,该核会导致不切实际的条件方差过小,从而在预测不确定性方面产生灾难性的过度自信。此外,该核固有的平滑性会导致数值病态,在实际应用中需要引入类似“nugget”项的变通方法。论文建议,总体上应避免使用解析核。 AI

影响 挑战了常用核函数的默认使用方式,可能影响机器学习应用中的模型开发和不确定性量化。

    为什么不使用高斯核

    arXiv:2608.26974v1 Announce Type: new Abstract: Kernels measure similarity or correlation in tasks such as regression and classification. The Gaussian kernel, other names of which include squared exponential and radial basis function kernel, is one of the most popular in Gaussian…
