OpenKernel Library

OpenKernel is a library for creating, combining and using kernels for machine learning applications. The current focus of library is on rational kernels. It is based on the OpenFst library.

This library is being developed by C. Allauzen, M. Mohri and A. Rostamizadeh. It is intended to be comprehensive, flexible, efficient and scale well to large-scale problems. It is an open source project distributed under the Apache license. This work has been partially supported by Google Inc.

Latest version includes algorithms for learning kernels and kernel ridge regression.
