Multivariate Pattern Analysis in Python |
Bases: mvpa.mappers.base.Mapper
Mapper to combine multiple samples into a single sample.
Note
This mapper is somewhat unconventional since it doesn’t preserve number of samples (ie the size of 0-th dimension).
Parameters: |
|
---|
Project an ND matrix into N+1D matrix
This method also handles the special of forward mapping a single ‘raw’ sample. Such a sample is extended (by concatenating clones of itself) to cover a full boxcar. This functionality is only availably after a full data array has been forward mapped once.
Return type: | array |
---|
Uncombine features back into original space.
Samples which were not touched by forward will get value 0 assigned
