Builds a new Dataset with the kernel as the records and the same targets as the input one.
Parameters
x
: A dataset with a matrix of records (#records, #features) and any targets
Returns
A new dataset with:

x.records()
according to the parameters on which this method is called - targets: same as
x.targets()
