Nelson Morgan, Deputy Director of ICSI

morgan @

Nelson Morgan has been a speech and signal processing/machine learning researcher and the former director of ICSI as well as a professor in residence emeritus at UC Berkeley. He led the speech research effort at ICSI from 1988 through 2012 and worked on speech and brain signal processing since 1980. With Hervé Bourlard, he was an originator of the "hybrid system" approach to speech recognition (neural networks used probabilistically with HMMs), and with Hynek Hermansky was the co-inventor of signal processing techniques that were used in millions of cell phones. More recently he has been studying best practices for political campaigns in order to further his ideals.
