## What it is
A Chinese translation of the O'Reilly book 'Feature Engineering for Machine Learning', maintained by ApacheCN and readable online or self-hosted via Docker, pip, or npm. It covers numeric, text, and categorical feature engineering, TF-IDF, PCA, and automated feature extraction with deep learning.

## Use cases
- learn feature engineering for machine learning in Chinese
- understand TF-IDF and bag-of-words feature scaling
- study PCA dimensionality reduction with examples
- learn categorical feature encoding techniques
- self-host a machine learning book documentation site
- find Chinese ML learning materials

## When to choose
- you prefer reading about feature engineering in Chinese
- you want a free online reference on feature extraction and scaling
- you need a self-hostable documentation copy of the book

## When to avoid
- you need an executable feature engineering library rather than a book
- you require up-to-date content, as the translation is of an early-release edition
- you need commercial-use rights, since the translation is CC BY-NC-SA licensed

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, machine-learning
- domain: machine-learning, tutorials, education
- platform: python
- tags: chinese-translation, feature-engineering, book-translation, apachecn, tf-idf, pca, web-server, docker, nodejs
