Vowpal Wabbit: A Machine Learning System ( Paris Machine Learning Meetup "Hors Série" #4 Season 2 )


Following up on meetup #6 Season 2, John Langford just gave us a tutorial presentation on Vowpal Wabbit this morning in Paris (Thank you Christophe and AXA for hosting us). Here are the slides:
Here is some additional relevant background material.
Much like the example Leon Bottou gave us on counterfactual reasoning, ( see his slides: Learning to Interact ) a year ago. I very much liked the exploration bit for policies evaluation: if you don't explore you just don't know and prediction errors are not controlled exploration.


which will be the subject of John's presentation at ICML in Lille next week:

Learning to Search Better than Your Teacher by Kai-Wei Chang, Akshay Krishnamurthy, Alekh Agarwal, Hal Daume, John Langford
