kernel_weights: Compute Gaussian Kernel Weights

Description

kernel_weights computes Gaussian kernel weights given a data matrix X and a scale parameter phi. Namely, the lth weight w[l] is given by $$w[l]=exp(-phi||X[,i]-X[,j]|{|}^2)$$, where the lth pair of nodes is (i,j).

Usage

kernel_weights(X, phi = 1)

Arguments

X

The data matrix to be clustered. The rows are the features, and the columns are the samples.

phi

The nonnegative parameter that controls the scale of kernel weights

Value

• A vector w of weights for convex clustering.
