I have download 100 billion word Google news pretrained vector file. On top of that i am also training my own 3gb data producing another pretrained vector file. Both has 300 fea
Those are my methods:
Download the crops from Google news and merge them into your data, then train them!
Divide your data set into 2 equal size data set, then train both of them. Now you have 3 models, so you can use blending method to predict.
I hope these may help you!
