Complete Natural Language Processing (NLP) Tutorial in Python! (with examples)

Learn data skills with hands-on exercises & tutorials at Datacamp! https://datacamp.pxf.io/c/3588040/101... In this video we go through the major concepts in natural language processing using Python libraries! We use examples to help drill down the concepts. There is content in this video for all skill levels (beginners to experts). I originally recorded this video for the PyCon Conference. GitHub repo: https://github.com/KeithGalli/pycon2020 Patreon:   / keithgalli   YT Membership:    / kgmit   Some of the topics we cover: Bag-of-words Word vectors Stemming/Lemmatization Spell correction Transformer Architecture (Attention is all you need) State of the art models (OpenAI GPT, BERT) Some of the libraries used: sklearn spaCy NLTK TextBlob Hope you enjoy & let me know if you have any questions!
