Pytorch tutorials exercices

[MokaddemMouna]

Hi Robert,

I followed your Pytorch tutorials for NLP and I implemented 2 exercices that you proposed.
The Cbow and the character level enriching of word embeddings of the POS tagger.

I would appreciate if you review/comment my implementation and why not discuss about it.

Here is the repo's link: https://github.com/MokaddemMouna/Pytorch

Thanks.
