WebTo measure the dependency between each feature and label, we use the Hilbert-Schmidt Independence Criterion, which is a kernel-based independence measure. By modeling the kernel functions with neural networks that take a few labeled instances in a task as input, we can encode the task-specific information to the kernels such that the kernels ... WebHilbert-Schmidt norm) to measure dependence — we call the resulting quan-tity the Hilbert-Schmidt Independence Criterion (HSIC).2 It turns out that the empirical estimate of HSIC is identical to the quadratic dependence measure of Achard et al.

WebAnother algorithm called “GraphLIME” can be used for graph neural networks for classification applications. It extends LIME to work in a non-linear environment by sampling N-hop network neighbors and using the Hilbert–Schmidt independence criterion Lasso (HSIC Lasso) as surrogate models . WebHilbert-Schmidt Independence Criterion For a comprehensive introduction to the HSIC see for example [22] or [4]. For our purposes it is sufficient to describe the calculation of the HSIC statistic for a finite sample {(x1 , y1 ), . . . , (xn , yn )}. The HSIC is based on a kernel function, a similar- ity function between sample points.
