...It replaces the book's original MXNet implementations with executable PyTorch examples while preserving the broader instructional material. Chapter code is organized as Jupyter notebooks so learners can run and modify examples interactively. The accompanying documentation is stored in Markdown and published as a browsable Docsify website. The material is intended for beginners with basic Python, linear algebra, calculus, and probability knowledge rather than prior machine-learning experience. It can be studied online, served locally, or viewed through a Docker-based documentation environment.
