Archetypal Analysis Package

This package is a python implementation of the Archetypal Analysis (AA) proposed by Cutler and Breiman (1994). The package is developed in a similar style to the sklearn libraries which are familiar to the machine learning (ML) community. The main functions are "fit", "fit_transform", and "transform". By calling the fit (fit_transform) function, the archetypes of the data set are extracted. In addition, a range of utility functions are provided to perform different visualisations. A tutorial Jupyter notebook demonstrates the functionalities that the package offers.本软件包是Cutler与Breiman于1994年提出的原型分析（Archetypal Analysis, AA）的Python实现。其开发风格与机器学习（ML）社区广为熟知的sklearn库保持一致，核心方法包含`fit`、`fit_transform`以及`transform`。通过调用fit（或fit_transform）方法，即可从数据集中提取原型。此外，本软件包还提供了一系列实用工具函数，用于实现多样化的可视化操作。配套的Jupyter教程笔记本可演示本软件包提供的全部功能。
