From Text to Numbers

Tokenization is the first step in NLP - breaking text into smaller units (tokens) that models can process. Each token gets converted to a number, creating the input for language models.

🎯 Why Tokenize?

Convert to numbers: Models need numerical input
Handle vocabulary: Manage fixed-size vocab
Process efficiently: Enable batch processing
Handle unknowns: Deal with rare words
