Since only a small number of neurons in primary auditory cortex are activated in encoding acoustic stimuli and sparse independent events are used to represent the characteristics of the neurons. Each individual dictionary is learned from individual speaker samples where dictionary atoms correspond to the cortex neurons. The neuron responses possess statistical properties of acoustic signals in auditory cortex so that the activation distribution of individual speaker\u2019s neurons is approximated as the characteristics of the speaker. Kurtosis is an efficient approach to measure the sparsity of the neuron from its activation distribution, and the vector composed of the kurtosis of every neuron is obtained as the model to characterize the speaker\u2019s voice. The experimental results demonstrate that the kurtosis model outperforms the baseline systems and an effective identity validation function is achieved desirably. <\/jats:p>","DOI":"10.1142\/s0218001416590084","type":"journal-article","created":{"date-parts":[[2015,10,27]],"date-time":"2015-10-27T03:22:45Z","timestamp":1445916165000},"page":"1659008","source":"Crossref","is-referenced-by-count":3,"title":["Speaker Verification via Modeling Kurtosis Using Sparse Coding"],"prefix":"10.1142","volume":"30","author":[{"given":"Wei","family":"Wang","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Harbin Institute of Technology, 92 West Dazhi Street, Nan Gang District Harbin, 150001, P.
