Inspired by Smith/Lewicki’s overcomplete matching pursuit, I’m looking
to put together “spikegrams” starting with Gammatones using matching
The problem I’m coming up against in the major Matching Pursuit libraries
(mptk, wmpalg, scilearn) is that they ask for discreet atoms and Gammatones are
parameterized with attack, decay and phase (not to mention amp/freq). It seems like
a dictionary that covers all phases,attacks,decays, and freqs would be super
Am I off base here? Are there any libraries out there that can do this? I’m
totally naive to this stuff.
