TopicVec

TopicVec is the source code for "Generative Topic Embedding: a Continuous Representation of Documents" (ACL 2016).

PSDVec (in folder 'psdvec') is the source code for "A Generative Word Embedding Model and its Low Rank Positive Semidefinite Solution" (EMNLP 2015).

Update v0.7:

The topic inference is now 6 times faster.

Update v0.6:

Algorithm update:

topicvecDir.py: uses exact inference instead a second-order approximation in the M-step.

Update v0.5:

Main algorithm:

topicvecDir.py: uses a Dirichlet prior for topic mixting proportions.
