Information Theory
title: Introduction to Information Theory¶
Introduction¶
Information theory quantifies uncertainty and information content. Concepts such as entropy and cross-entropy are deeply entwined with language modeling and loss functions used to train neural networks.
Knowledge Points¶
- Entropy
- Cross-Entropy
- Kullback-Leibler (KL) Divergence
- Why information theory matters for language modeling
- Manual entropy calculation exercise
- Implementing cross-entropy loss
