Great data sets for Topological Data Analysis.

Project description

PyPI version Build Status Codecov License: MIT


Data sets apt for Topological Data Analysis. This project is a part of scikit-tda.


At SoCG 2018, there was discussion about the need for data sets for two main purposes

  • Benchmarking new algorithms
  • Demonstrating benefits of TDA

Data generation

We provide constructors for some synthetic data sets that are popular in development and testing of TDA techniques.

  • Torus
  • Klein Bottle
  • Swiss Roll

Setup and Usage

You can install from Pypi

pip install tadasets

or from source

git clone
cd tadasets
pip install -e .

Examples of usage is

import tadasets
data = tadasets.sphere(n=1000, r=10)


import tadasets
data = tadasets.swiss_roll(n=1000, r=10)


This package is in the very early stages of development. As I think of shapes and data sets, I add them. If you have ideas, please do suggest them in an issue and submit a pull request! All contributions are welcome.
