Representation and Processing of Acoustic Information in a Biomimetic Neural Network

Abstract

The effectiveness of artificial neural network models depends strongly on the way in which the information to be learned is presented to the network. Use of biologically relevant mechanisms is likely to yield effective syntactic systems as well as understanding the performance of biological systems. We developed a model of the dolphin cochlea and used this model to produce the representations used by a neural network to model the delayed matching-to-sample performance of a bottlenosed dolphin. The model yielded psychophysical functions and matching choice accuracy similar to those obtained from the dolphin....
