Learning Tree Structures for Conditional Random Fields (CRFs)

This page provides code from my project on learning tree structures for Conditional Random Fields (CRFs). This code is a somewhat improved version of the code used for this paper:
Joseph K. Bradley and Carlos Guestrin. Learning Tree Conditional Random Fields. International Conference on Machine Learning (ICML), 2010.
bibtex/abstract PDF

Note: This code is part of a larger SELECT Lab codebase which is available but still being improved for actual release. See my SILL Project Page for info on that codebase.
