Vowpal Wabbit

Participants : Jérémie Mary, Romaric Gaudel, Thomas Chabin.

Vowpal Wabbit is a GPL project leaded by John Langford at Yahoo! Research and now at Microsoft. The goal is to build a very fast, distributed and large scale machine learning software. https://github.com/JohnLangford/vowpal_wabbit/wiki . We worked on the optimization of the parser and on the memory structures of the i/o. The modifications have been accepted for commit in the main branch and allow an average division by two of all execution times.
