Exact Heat Kernel on a Hypersphere and Its Applications in Kernel SVM
Many contemporary statistical learning methods assume a Euclidean feature space. This paper presents a method for defining similarity based on hyperspherical geometry and shows that it often improves the performance of support vector machine compared to other competing similarity measures. Specifica...
