From the post:
The live broadcast of the Microsoft Research Machine Learning Summit will include keynotes from machine learning experts and enlightening discussions with leading scientific and academic researchers about approaches to challenges that are raised by the new era in machine learning. Watch it streamed live from Paris on April 23, 2013, 13:30–17:00 Greenwich Mean Time (09:30–13:00 Eastern Time, 06:30–10:00 Pacific Time) at http://MicrosoftMLS.com.
I would rather be in Paris but watching the live stream will be a lot cheaper!
