NiaAML is an automated machine learning Python framework based on nature-inspired algorithms for optimization. The name comes from the automated machine learning method of the same name [1]. Its goal is to efficiently compose the best possible classification pipeline for the given task using components on the input. The components are divided into three groups: feature seletion algorithms, feature transformation algorithms and classifiers. The framework uses nature-inspired algorithms for optimization to choose the best set of components for the classification pipeline on the output and optimize their parameters. We use NiaPy framework for the optimization process which is a popular Python collection of nature-inspired algorithms. The NiaAML framework is easy to use and customize or expand to suit your needs.
The NiaAML framework allows you not only to run full pipeline optimization, but also separate implemented components such as classifiers, feature selection algorithms, etc. It supports numerical and categorical features as well as missing values in datasets.
Documentation: https://niaaml.readthedocs.io/en/latest/,
Tested OS: Windows, Ubuntu, Fedora, Linux Mint and CentOS. However, that does not mean it does not work on others.
Installation
pip
Install NiaAML with pip3:
pip3 install niaamlIn case you would like to try out the latest pre-release version of the framework, install it using:
pip3 install niaaml --preInstall From Source
