Data science is a growing discipline; there are so many techniques, data sets, and people in the field that it’s increasingly hard to keep track of what is happening.  In this talk, Anthony Goldbloom describes the sorts of data sets that Kaggle (his company) has been publishing as part of its data-science contests, aimed at crowdsourcing solutions. If you’re interested in how data science techniques are being used to solve problems, or are trying to understand just where and how data science methods differ from others, this talk should be of interest.
