How Perplexity Measures Language Model Performance

Imagine you're reading a book and can easily guess the next word based on the context. That's what language models strive for! Perplexity is a tool that helps us measure how well they're doing.

Predicting the Next Word: The Challenge of Language Modeling

Language models are AI tools that deal with understanding and generating human language. A core challenge is predicting the most likely word that comes next in a sequence. Think of it like reading a story and trying to guess what happens next! Perplexity helps us evaluate how good these guesses are.
