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, and performance evaluation for symbolic regression models.
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.
To install the package, run the following command in your terminal:
pip install symbolic-regression-toolkit
