Usage

rbfkernel_b(mat, K = 3, sigma = 1)

Arguments

mat

Matrix: matrix should have samples as columns and rows as features

K

Numerical value: the number of nearest neighbours to use when calculating local sigma

sigma

Numerical value: a global sigma, usually left to 1 which has no effect

Value
