%description
The Vowpal Wabbit (VW) project is a fast out-of-core learning system.

Vowpal Wabbit is notable as an efficient scalable implementation of online
machine learning and support for a number of machine learning reductions,
importance weighting, and a selection of different loss functions and
optimization algorithms.
