vowpal-wabbit – fast and scalable online machine learning algorithm

Vowpal Wabbit is a fast online machine learning algorithm. The core algorithm is specialist gradient descent (GD) on a loss function (several are available). VW features:

  • flexible input data specification
  • speedy learning
  • scalability (bounded memory footprint, suitable for distributed computation)
  • feature pairing
