* feat: add v1/v2 versioning and language selector for mdbook - Copy current content to v1/ directory (1st Edition) - Create v2/ directory with new TOC structure (2nd Edition) and placeholder chapters - Add version selector (V1/V2) and language toggle (EN/ZH) in top-right nav bar - Add build scripts: build_mdbook_v1.sh, build_mdbook_v2.sh - Update assemble_docs_publish_tree.py to support v1/v2 deployment layout - Fix mdbook preprocessor to use 'sections' key (v0.4.43 compatibility) - Update .gitignore for new build artifact directories - Deployment layout: / = v2 EN, /cn/ = v2 ZH, /v1/ = v1 EN, /v1/cn/ = v1 ZH Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * build: update CI to build and verify all four books (v1/v2 x EN/ZH) - Clarify step names: "Build v2 (EN + ZH)" and "Build v1 (EN + ZH)" - Add verification step to check all four index.html outputs exist - Deploy workflow assembles: / = v2 EN, /cn/ = v2 ZH, /v1/ = v1 EN, /v1/cn/ = v1 ZH Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: gracefully skip missing TOC entries instead of crashing resolve_toc_target() now returns None for missing files instead of raising FileNotFoundError. This fixes v1 EN build where chapter index files reference TOC entry names that don't match actual filenames.

Chapter Summary
-
In order to achieve a balance between usability and performance, modern machine learning systems utilize Python for frontend programming and C/C++ for backend programming.
-
It is expected from a machine learning framework to offer programming support for all aspects of a machine learning application workflow. This is usually delivered through high-level Python APIs, which facilitate activities such as data processing, model definition, loss function determination, model training, and model testing.
-
Large DNNs can be constructed by stacking neural network layers.
-
Various technologies are used to facilitate interoperability between Python and C, with pybind being a popular choice in machine learning frameworks.
-
Machine learning frameworks typically offer a variety of C/C++ interfaces, allowing users to define and register operators implemented in C++. These operators enable users to create various framework extensions, such as high-performance models, data processing functions, and optimizers.
