Jordan Cohen calls himself 'sort of an engineer and sort of a linguist.' This diverse background has been the foundation for his long history working with speech technology, including almost 30 years with government agencies, with a little time out in the middle to work in IBM's speech recognition group. Until recently he was the chief technology officer of(More)
As authors of the seminal textbook, <em>Computer Architecture: A Quantitative Approach</em> (4th Edition, Morgan Kaufmann, 2006), John Hennessy and David Patterson probably don&#8217;t need an introduction.
