Software

• str2vec is a toolkit for computing vector-space representations for variable-length phrases using recursive autoencoders (RAE). In this document, we demostrate
• How to train RAEs in an unsupervised and parallelized manner
• And how to compute vector-space representations for phrases once the RAE is trained
• hiero-decoder-py is a hierarchical phrase-based translation decoder which supports parallel decoding. New feature functions can also be implemented easily.
