Temporary repository used for collaboration on application of for multiple languages.

How to train classifier

$ python -m ulmfit lm --dataset-path data/wiki/wikitext-103 --bidir=False --qrnn=False --tokenizer=vf --name 'bs40' --bs=40 --cuda-id=0  -  train 20 --drop-mult=0.9
...
Model dir: data/wiki/wikitext-103/models/vf60k/lstm_bs40.m
...
$ python -m ulmfit cls --dataset-path data/imdb --base-lm-path data/wiki/wikitext-103/models/vf60k/lstm_bs40.m - train 20

how to contribute

We have a fork of fastai to propose changes to fastai.text, with a branch for this project: https://github.com/n-waves/fastai/tree/ulmfit_multilingual

Let us know that you want to start collaboration on fastai forum thread: Multilingual ULMFIT and you will get access to both repositories.

• Follow the developer installation of fastai
• Add n-waves/fastai as additional remote as described here: https://help.github.com/articles/adding-a-remote/

Here is what I did:

$ cd fastai
$ git remote add n-waves https://github.com/n-waves/fastai.git
$ git remote -v 
n-waves	https://github.com/n-waves/fastai.git (fetch)
n-waves	https://github.com/n-waves/fastai.git (push)
origin	https://github.com/fastai/fastai.git (fetch)
origin	https://github.com/fastai/fastai.git (push)

$ git fetch n-waves
$ git checkout ulmfit_multilingual
Branch 'ulmfit_multilingual' set up to track remote branch 'ulmfit_multilingual' from 'n-waves'.
Switched to a new branch 'ulmfit_multilingual'

$ git push --set-upstream n-waves ulmfit_multilingual  # to automatically push ulmfit_multilingual branch to the n-waves repo
