Deep Transfer Learning in NLP with Python

Dipanjan Sarkar (~dipanjan)




Handling tough real-world problems in Natural Language Processing (NLP) include tackling with class imbalance and the lack of availability of enough labeled data for training. Thanks to the recent advancements in deep transfer learning in NLP, we have been able to make rapid strides in not only tackling these problems but also leverage these models for diverse downstream NLP tasks - which I like to call multi-task NLP

The intent of this session will be to look at various SOTA models in deep transfer learning for NLP with hands-on examples in Python including:

  • CNNs \ LSTMs with pre-trained embeddings
  • Universal Sentence Encoders (NNLM \ USE)
  • Transformers (BERT \ DistilBERT)

We will then take a look at true multi-task learning for NLP by leveraging the powerful pipeline construct of the transformers package where we will look at tacking the following tasks with just a few lines of code in Python!

  • Named Entity Recognition
  • Fill in the next word
  • Sentiment Analysis
  • Question & Answering System
  • Text Summarization


Having a background knowledge of Natural Language Processing and Deep Learning helps. This will be an applied-DL \ hands-on session for the most part.
