Classic NLP Explained: Text Preprocessing, One-Hot, Bag-of-Words, TF-IDF

Natural Language Processing (NLP) is how AI learns to read human language. But how do we teach a computer to understand context, emotion, and text chaos?

For my first teaching video I break down the essential steps that turn raw text into the numbers a machine can process.

You'll learn:

What is NLP and how AI started learning language.

Pre-Processing: Tokenization, Stemming, Lemmatization and Stop Words

Words to Numbers: One-Hot-Encoding (OHE) Bag-of-Words (BoW), and the crucial TF-IDF (Term Frequency-Inverse Document Frequency).
