Kaggle Competition (Facebook recruiting): Human or Robot?
Facebook and Kaggle are launching an Engineering competition for 2015 - leaders will earn an opportunity to interview for a software engineer at Facebook, working on world class Machine Learning problems. In this competition, you'll be chasing down robots for an online auction site.

In this competition, you'll be chasing down robots for an online auction site. Human bidders on the site are becoming increasingly frustrated with their inability to win auctions vs. their software-controlled counterparts. As a result, usage from the site's core customer base is plummeting.
Whether you are interested in Facebook or not, this should be a fun competition for any ML/DM person who wants to test her meddle against other practitioners.
