The From Data to Knowledge workshop May 7-11 at Berkeley should be of interest to the many people encountering streaming data in different disciplines. It’s run by a group of astronomers who encounter streaming data all the time. I met Josh Bloom recently and he is broadly interested in a workshop covering all aspects of Machine Learning on streaming data. The hope here is that techniques developed in one area turn out useful in another which seems quite plausible. Particularly if you are in the bay area, consider checking it out.
