Inheritance diagram of WaveletPacketMapper

class mvpa2.mappers.wavelet.WaveletPacketMapper(level=None, **kwargs)

Convert signal into an overcomplete representaion using Wavelet packet

Available conditional attributes:

  • calling_time+: Time (in seconds) it took to call the node
  • raw_results: Computed results before invoking postproc. Stored only if postproc is not None.
  • training_time+: Time (in seconds) it took to train the learner

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.

enable_ca : None or list of str

Names of the conditional attributes which should be enabled in addition to the default ones

disable_ca : None or list of str

Names of the conditional attributes which should be disabled

dim : int or tuple of int

dimensions to work across (for now just scalar value, ie 1D transformation) is supported

wavelet : str
