Learning from presentation or slides can be a much easier than from papers. I was reminded of that when I ran across Martin Wainwright's excellent class on Graphical Models. It has lecture notes *and* videos online.
Another large repository of machine learning related videos is the repository organized by the Pascal Network. You may run into a couple of bugs, but Sebastjan Mislej (sebastjan dot mislej dot ijs dot si) is very quick at fixing them when you email him.
Does anyone else have a favourite set of Machine Learning slides/notes/videos online?
