This is a very simple test of vowpal wabbit's contextual bandits using the dataset from Tony Jebara's ML for Personalization class at Columbia. Specifically I wanted to see what varying the cb_type param would do.
The results here are surprising (to me) in that the take rate varies so much by cb_type. Is that expected behavior?
