mappers.wavelet

Module: mappers.wavelet

Inheritance diagram for mvpa.mappers.wavelet:

Wavelet mappers

Classes

WaveletPacketMapper

class mvpa.mappers.wavelet.WaveletPacketMapper(level=None, **kwargs)

Bases: mvpa.mappers.wavelet._WaveletMapper

Convert signal into an overcomplete representaion using Wavelet packet

Initialize WaveletPacketMapper mapper

Parameters:level (int or None) – What level to decompose at. If ‘None’ data for all levels is provided, but due to different sizes, they are placed in 1D row.

WaveletTransformationMapper

class mvpa.mappers.wavelet.WaveletTransformationMapper(dim=1, wavelet='sym4', mode='per', maxlevel=None)

Bases: mvpa.mappers.wavelet._WaveletMapper

Convert signal into wavelet representaion

Initialize _WaveletMapper mapper

Parameters:

• dim (int or tuple of int) – dimensions to work across (for now just scalar value, ie 1D transformation) is supported
• wavelet (basestring) – one from the families available withing pywt package
• mode (basestring) – periodization mode
• maxlevel (int or None) – number of levels to use. If None - automatically selected by pywt
