squareNorm {ZVCV} | R Documentation |
Squared norm matrix calculation
Description
This function gets the matrix of square norms which is needed for all kernels. Calculating this can help to save time if you are also interested in calculating the median heuristic, handling multiple tuning parameters or trying other kernels.
Usage
squareNorm(samples, nystrom_inds = NULL)
Arguments
samples |
An |
nystrom_inds |
The (optional) sample indices to be used in the Nystrom approximation (for when using aSECF). |
Value
An N
by N
matrix of squared norms between samples (or N
by m
where m
is the length of nystrom_inds
).
