Symbolic Regression/Equation Discovery Toolkit

Symbolic Regression/Equation Discovery Toolkit

Documentation: https://smeznar.github.io/SymbolicRegressionToolkit

This repository provides a Python-based toolkit for equation discovery/symbolic regression. Currently, the toolkit contains code for transforming infix expressions into trees, parameter estimation, performance evaluation for symbolic regression models, generating sets of expressions, benchmarking, ...

Currently, we only support (vanilla) mathematical expressions, however, we provide a simple interface for adding custom symbols. In the future, we might extend our functionality to support more advanced expressions (differential equations, PDEs, ...).

A simple example of how to use the toolkit can be found in the examples folder. Script examples/SR_evaluation_minimal_example.py contains a minimal example of how to use the toolkit for evaluating Symbolic Regression models. Script examples/parameter_estimation_minimal_example.py contains a minimal example of how to use the toolkit for parameter estimation. Lastly, script examples/customization.py shows how we can customize various parts of the toolkit and create executable python functions from infix expressions.

Installation

To install the lastest release of the package, run the following command in your terminal:

pip install symbolic-regression-toolkit

Otherwise, you can install the latest build with the command:
