A Hilbert space embedding of a distribution---in short, a kernel mean embedding---has recently emerged as a powerful tool for machine learning and inference. The basic idea behind this framework is to map distributions into a reproducing kernel Hilbert space (RKHS) in which the whole arsenal ...

In 2020, Isolation Distributional Kernel or IDK is introduced to measure the similarity of two distributions [6], based on the framework of kernel mean embedding [8]. The first application of IDK is a kernel-based point anomaly detector that needs no learning, unlike OCSVM [9]. Through IDK...
