The developed mathematical model of the human auditory pathway consists of three components, i.e. the nonlinear feature extraction from cochlea to auditory cortex, the binaural processing at superior olivery complex, and the top-down attention from higher brain to the cochlea. The feature extraction is based on information-theoretic sparse coding throughout the auditory pathway. Also, the time-frequency masking is incorporated as a model of the lateral inhibition in both time and frequency domain. The binaural processing is modeled as the blind signal separation and adaptive noise canceling based on the independent component analysis with hundreds of time-delays for noisy reverberated signals. The Top-Down (TD) attention comes from familiarity and\/or importance of the sensory information, i.e. the sound, and a simple but efficient TD attention model had been developed based on the error backpropagation algorithm. Also, the binaural processing and top-down attention are combined for speech signals with heavy noises. This auditory model requires extensive computing, and special hardware had been developed for real-time applications. Experimental results demonstrate much better recognition performance in real-world noisy environments.<\/jats:p>","DOI":"10.1142\/s0219878904000367","type":"journal-article","created":{"date-parts":[[2005,4,29]],"date-time":"2005-04-29T11:53:56Z","timestamp":1114775636000},"page":"345-356","source":"Crossref","is-referenced-by-count":0,"title":["MODELING AUDITORY PATHWAY FOR INTELLIGENT INFORMATION ACQUISITION"],"prefix":"10.1142","volume":"01","author":[{"given":"HYUNG-MIN","family":"PARK","sequence":"first","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"CHUNG Moon Soul Center for BioInformation and BioElectronics, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"JONG-HWAN","family":"LEE","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"Department of Electrical Engineering and Computer Science, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"TAESU","family":"KIM","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"Department of BioSystems, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"CHUNG Moon Soul Center for BioInformation and BioElectronics, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"UN-MIN","family":"BAE","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"BYUNG TAEK","family":"KIM","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"KI-YOUNG","family":"PARK","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"CHANG-MIN","family":"KIM","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"Department of Electrical Engineering and Computer Science, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]},{"given":"SOO-YOUNG","family":"LEE","sequence":"additional","affiliation":[{"name":"Brain Science Research Center, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"Department of BioSystems, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"Department of Electrical Engineering and Computer Science, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"},{"name":"CHUNG Moon Soul Center for BioInformation and BioElectronics, Korea Advanced Institute of Science and Technology, 373-1 Guseong-dong, Yuseong-gu, Daejeon 305-701, Korea (South), Korea"}]}],"member":"219","published-online":{"date-parts":[[2012,1,25]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1162\/089976698300017746"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-2312(02)00529-5"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1995.7.6.1129"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1016\/S0042-6989(97)00121-1"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1121\/1.1383297"},{"key":"rf6","first-page":"347","volume":"26","author":"Clement R.
