This talk was a preview of the Theano code (and the ideas behind word-embedding) that I plan to release soon (i.e. so that people can play around with it before May-2015).
A working solution to the Billion Word Imputation challenge will hopefully appear on my GitHub account shortly (was planned for 15-Jan-2015, still in process).
Key papers to have a look at :
Mikolov 2012 and the Word2Vec code, and also a nice Python version, with interesting optimization talk.
