Module 4: Text as Vectors and Classification

What you need first

• Module 3, or at least its lab: the tidewell-inbox repository with clean, the keyword router, tokens.py and entities.py. The Module 4 lab can rebuild those files if they are missing.
• Basic Python. Module 2, Lesson 1 helps: what a token is.
• A Google account for Colab and Drive. No model key: nothing in this module calls a hosted model.
