CLSP kicks off Frederick Jelinek Memorial Summer Workshop

June 29, 2016

The Third Frederick Jelinek Memorial Summer Workshop, organized and hosted by the Johns Hopkins Center for Language and Speech Processing, is under way. The six-week workshop—which marks the 21st summer workshop in CLSP’s history—seeks to advance and promote machine learning for speech language and computer vision technology. Workshop attendees—comprising researchers from academia, government and industry […]
