Document Classification Workshop (NLP, Text Processing, Machine Learning) [Python, scikit-learn]

You can forklift this project in your MatrixDS account if you would like to follow along: https://community.platform.matrixds.com/community/project/5d5d5a3cd3af39f8147b8100/dashboard We will learn about NLP techniques to process a text corpus to prepare for Machine Learning applications, including

  • stop word removal

  • tokenization

  • lemmatizing

  • n-grams

  • count-vectorizer, and TFIDF

  • applying supervised learning (random forests) to vector representation of documents for classification

  • Hyper Parameter Tuning

  • Model evaluation

Based on the NLP jupyter notebooks in repo 1 And repo 2
