TaDAsets

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

Motivation

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 https://github.com/scikit-tda/tadasets
cd tadasets
pip install -e .

Examples of usage is

import tadasets
data = tadasets.sphere(n=1000, r=10)
tadasets.plot3d(data)

or

import tadasets
data = tadasets.swiss_roll(n=1000, r=10)
tadasets.plot3d(data)

Contributions

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.
