"Videolectures.net is a new web service,
still in beta, that provides “free video lectures from the world’s leading and
prominent scientists”. The most common topics are drawn from computer science
with an emphasis on Semantic Web and
machine learning,
although there is an obligatory lecture by Noam
Chomsky.
The videos
include lectures, tutorials, paper presentations and informal interviews. Most
of the current ones are from recent conferences, including NIPS, ICML, ECML and ISWC as well as various workshops and summer schools
Users can leave
comments and the system will recommend videos based on “visitors who watched
this lecture also watched…”. I
While I doubt
that Google will pay a billion dollars for this company, it looks like a great
resource for CS researchers."
