Reprocess data for Nyström approximation

Apply preprocessing to new data for projection using a Nyström approximation. This method overrides the default reprocess.projector to handle the fact that Nyström components are in kernel space (not feature space).

Usage

# S3 method for class 'nystrom_approx'
reprocess(x, new_data, colind = NULL, ...)

Arguments

x

A nystrom_approx object

new_data

A matrix with the same number of columns as the original training data

colind

Optional column indices (not typically used for Nyström)

...

Additional arguments (ignored)

Value

Preprocessed data matrix
