|Coherent ICA: Implications for Auditory Signal Processing
Simon Haykin, McMaster University, Canada
We describe a novel algorithm, called Coherent Independent Components Analysis, and referred to as Coherent ICA for short. The algorithm, rooted in information-theoretic learning, exploits the combined use of the Infomax and Imax principles. Experimental results, based on the auditory coding of natural sounds, are presented that demonstrate the ability of coherent ICA to extract the envelope of amplitude-modulated sounds in a manner similar to the behaviour of neurons in the cochlear nucleus and inferior colliculus.
|Progress in the Study of Auditory Scene Analysis
Albert S. Bregman, McGill University, Canada
The early research on auditory scene analysis (ASA) the subject of my talk at the corresponding IEEE workshop in 1995 has been followed by many exciting studies that have opened up new directions of research. I will discuss some of them under the following headings:
