Neural Networks and Deep Learning (nndl)

Free Chinese-language textbooks on neural networks and deep learning, from beginner to advanced.

What it does

This repository hosts free e-book versions of two Chinese textbooks on neural networks and deep learning by Qiu Xipeng, plus tables of contents and a place to report errors.

The general edition uses stories and everyday comparisons, with fewer formulas, and goes up to large language models, AI agents and AI safety. The second edition is a full course text covering the theory, math and algorithms, with math appendices.

Both books are written in Chinese. A companion repository offers hands-on exercises using PyTorch.

Who it's for

Chinese-reading students and self-learners, from curious beginners to university-level learners.
