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. WebApr 3, 2024 · We introduce the HSIC (Hilbert-Schmidt independence criterion) bottleneck for training deep neural networks. The HSIC bottleneck is an alternative to the conventional cross-entropy loss and backpropagation that has a number of distinct advantages. It mitigates exploding and vanishing gradients, resulting in the ability to learn very deep …
WebSep 1, 2024 · Among the most interesting kernel dependence methods, we find the Hilbert–Schmidt Independence Criterion (HSIC) [6]. The method consists of measuring cross-covariances in a proper RKHS, and generalizes several measures, such as COCO, by using the entire spectrum of the cross-covariance operator, not just the largest singular … WebMay 12, 2024 · The authors proposed then to replace MI with another dependence measure tool: HSIC for Hilbert Schmidt Independence Criterion. HSIC bottleneck HSIC is just the norm of the cross-covariance matrix between two sets of variables. In our case, let’s consider a batch of input data X = (X₁, X₂, …, Xₘ).
