Fast out-of-core learning system

The Vowpal Wabbit VW project is a fast out-of-core learning system sponsored by Microsoft Research and previously Yahoo! Research.

There are two ways to have a fast learning algorithm a start with a slow algorithm and speed it up, or b build an intrinsically fast learning algorithm. This project is about approach b, and it’s reached a state where it may be useful to others as a platform for research and experimentation.

There are several optimization algorithms available with the baseline being sparse gradient descent GD on a loss function several are available.
