Optimal Transport Propagation (OTP)

A Label Propagation algorithm based on Optimal Transport

Installation and Dependencies

Optimal Transport Propagation is based on NumPy, Pandas and POT. So, make sure these packages are installed. For example, you can install them with pip:

pip3 install numpy pandas POT

It is recommend to use Python 3.8 from Anaconda distribution. All the codes for the article are tested on macOS Big Sur Version 11.2.3

Usage

To reproduce the results, a jupyter notebook is provided in ./Optimal_Transport_Propagation.ipynb. The experiment was designed to evaluate OTP on Iris and Digits datasets. To reproduce all the results in the paper, the other datasets are available on https://archive.ics.uci.edu.
