WebThe HSIC-based sensitivity measure can be understood in this way since the index HSIC(Xi,Y) results from the application of the Hilbert-Schmidt independence criterion (HSIC) on the pair (Xi,Y). This criterion is nothing but a special kind of dissimilarity measure between the joint probability distribution and the product of marginal distributions.

Webmethods for optimising the HSIC based ICA contrast. Moreover, a generalisation of HSIC for measuring mutual statistical independence between more than two random variables has already been proposed by Kankainen in [22]. It led to the so-called characteristic-function-based ICA contrast function (CFICA) [7], where HSIC can be just considered as
