Abstract

© 2015 IEEE. Cochlear implants provide functional hearing to people who are profoundly deaf or hearing impaired by replacing the function of missing inner hair cells with an array of stimulating electrodes. Previous studies developed a modeling framework for predicting the optimal number of electrodes, as well as the optimal locations and usage probabilities of electrodes, from an information theoretic perspective. However, the information theoretic method does not quantify the performance of electrode place discrimination. In this paper, we apply a so-called 'extreme-learning machine' to the cochlear implant model to calculate the electrode classification error rates. We also investigate th..
