Mapping between wave signal and syrinx equations #2

Open felixmzd opened 8 years ago

felixmzd commented 8 years ago

We train a classical reservoir to learn the differential equations of the syrinx model. They describe how RA dynamics are mapped to a soundwave i.e. they implement the syrinx in the songbird.

The sample output from Yildiz2011 Link can be used as teacher signal. As an input to the reservoir we generate a linear combination of sinewaves of different frequencies. We use 0.06 Hz as base frequency as well as waves of 5 different integer multiples thereof.

It would be interesing to learn the reverse mapping as well, i.e. from the soundwave to the syrinx activations p(t) and k(t). A gut feeling is that the multiple delayed copies of the soundwave signal as input to the reservoir could be useful to perfom this task.
