BERT: Pre-Training of Deep Bidirectional Transformers for Language Understanding
- pacala 8y agoFantastic! > The code and pre-trained model will be available at https://goo.gl/language/bert https://goo.gl/language/bert. Will be released before the end of October 2018.

- joepayne 8y agoeager for the incoming code-)
- zimzim 8y ago"We demonstrate the importance of bidirectional pre-training for language representations". can some one help me understand what bidirectional and pre-trained means?
- willwill100 8y ago* bidirectional - build representations of the current word by looking into both the future and the past * pre-trained - train on lots of language modelling data (e.g. billions of words of wikipedia) and then train on the task you really care about but starting from the parameters learnt from the language modelling task.
- wodenokoto 8y agoIs this comparable to fast.ai's ULMfit, which also promises an unsupervised pretrained model, that can be tuned to best state-of-the-art NLP tasks?
- jiuren 8y agoThe big picture is similar. But ULMfit uses amd-lstm for the language modeling, bert uses masked LM instead. Bert has some other tricks like sentence prediction as well.
