## 项目历史与用法

Ruby Classifier is a Ruby text-classification library and CLI providing Bayesian classification, LSI, logistic regression, k-nearest neighbors, TF-IDF vectorization, streaming training, persistence, and native LSI acceleration.

### 项目历史

The GitHub repository was created in 2008. The gemspec and README describe it as a Ruby library for text classification with Naive Bayes, LSI, logistic regression, kNN, TF-IDF, pluggable persistence, and a native C extension.

The modern 2.x series refreshed the package in late 2025 and 2026, adding current documentation at rubyclassifier.com and a CLI-oriented Homebrew distribution path.

### 采用历史

RubyGems reported 1,162,163 total downloads for the classifier gem, making the Ruby package history much larger than the Homebrew CLI footprint. Homebrew packages version 2.6.0 and reported 131 installs over the prior 365 days.

### 使用方式

As a Ruby gem, users require classifier classes for Bayes, LSI, logistic regression, kNN, and TF-IDF workflows. As a CLI, users can classify text with pretrained models, list models, train categories from files, and classify new strings.

### 为什么软件包爱好者会关心

classifier is notable because an old Ruby ML/text-processing gem now spans RubyGems, generated API docs, a dedicated docs site, native extension compilation, and a Homebrew CLI package.

### 时间线

- 2008: GitHub repository created.
- 2024: v1.4.4 released in the 1.x line.
- 2025: v2.0.0 released.
- 2026: v2.6.0 released and packaged by Homebrew as stable.

### Related projects

- The package relates to RubyGems and RubyDoc as its primary Ruby distribution and API documentation surfaces.
- Its README positions it against older forks by emphasizing additional algorithms, incremental LSI, streaming, persistence, and native acceleration.
