Hi Branislaw,
If your goal is to use Gabor atoms choosen according to a new criterion, you may want to follow the developer manual to create a new type of "block" inheriting from Gabor blocks, with its own update_frame() method (this is where, if my memory is correct, correlations are computed) and create_atom() method to generate an atom with coefficients matching your new correlation.
I hope this helps.

Changing the cost function [ Reply ]

Hi guys,

I'm using MPTK for some speech analysis and I was wandering - is it possible to change the cost function that MPTK minimizes? In other words I want to plug in my own function instead of the correlation used at the moment.
If so, can you point me to where in the code I can do this.
