Software

  1. str2vec is a toolkit for computing vector-space representations for variable-length phrases using recursive autoencoders (RAE). In this document, we demostrate
  2. hiero-decoder-py is a hierarchical phrase-based translation decoder which supports parallel decoding. New feature functions can also be implemented easily.
