New in version 0.10.2:

  • NLP
    • Customized forward-backward and viterbi for chain models
    • changes to the coreference data structures that support hierarchical models
    • new data loaders

    • initial dependency parser
  • BP
    • Refactoring to be faster and cleaner interface, with bugfixes

    • TimingBP to compare performance of the different variants of BP in the codebase
    • maxMarginal with threshold, to support PR curves
    • some initial parallelization
  • Max likelihood training
    • convenience constructors for selecting which families to update
    • pieces can use families for inference that are not updated

  • Trainer that uses Stochastic gradient descent

  • Cubbie
    • new united interface for serialization/persistence (including mongodb support)
  • Hierarchical Coref Model
    • added model that supports arbitrarily deep and wide hierarchy of entites, aka Wick, Singh, McCallum, ACL 2012
