Natural Language Processing 101 Workshop will be the fourth of the AI Masterclass series lectures delivered by resource persons from the Facebook AI Research (FAIR) Labs in France. In this class, we will seek to understand how we can use AI to teach computers how to understand human natural language. We will also be made aware of current systems deployed for NLP and their challenges. To crown the event, we'll show how one can use NLP to make their Messenger Bots intelligent.
