eZAutoML

Overview

eZAutoML is a framework designed to make Automated Machine Learning (AutoML) accessible to everyone. It provides an incredible easy to use interface based on Scikit-Learn API to build modelling pipelines with minimal effort.

The framework is built around a few core concepts:

1. Optimizers: Black-box optimization methods for hyperparameters.
2. Easy Tabular Pipelines: Simple domain-specific language to describe pipelines for preprocessing and model training.
3. Scheduling: Work in progress; this feature enables horizontal scalability from a single computer to datacenters by using airflow executors.

Installation

Package Distribution

The latest version of eZAutoML can be installed via PyPI or from source.

pip install ezautoml
ezautoml --help

Install from source

To install from source, you can clone this repo and install with pip:

pip install -e .

Usage

Command Line Interface

Not only it can be used programatically but we provide an extremely lightweight CLI api to instantiate tabular AutoML pipelines with just a single command, for example:

ezautoml --dataset data/smoking.csv --target smoking --task classification --trials 10 --verbose   

Options:

• dataset: Path to the dataset file (CSV, parquet...)
• target: The target column name for prediction
• task: Task type: classification/c or regression/r
• search: Black-box optimization algorithm to perform
• output: Directory to save the output models/results
• trials: Maximum number of trials inside an optimiation algorithm
• verbose: Increase logging verbosity
• version: Show the current version

For more detailed help, use:

ezautoml --help

There are future features that are still a work-in-progress and will be enabled in the future such as scheduling, metalearning, pipelines...

Python Script

You can also use eZAutoML within Python scripts (though this feature is still being developed). This will allow you to work through Python code or via custom pipelines in the future.
