Particle Competition and Cooperation

Python code for the semi-supervised learning method “particle competition and cooperation”. This particular code was used in my master’s thesis “Aid in Alzheimer’s disease diagnosis from magnetic resonance imaging using particle competition and cooperation“.

Getting Started

Installation

You need Python 3.7 or later to use pycc. You can find it at python.org.

The package is avaliable at PyPI. If you have pip, just run:

  1. pip install pypcc

or clone this repo to your local machine using:

  1. git clone https://github.com/caiocarneloz/pycc.git

Usage

The usage of this class is pretty similar to semi-supervised algorithms at scikit-learn. A “demo” code was added to this repository.

Parameters

As arguments, pycc receives the values explained below:

  • n_neighbors: value that represents the number of neighbours in the graph build.
  • pgrd: value from 0 to 1 that defines the probability of particles to take the greedy movement.
  • delta_v: value from 0 to 1 to control changing rate of the domination levels.
  • max_iter: number of epochs until the label propagation stops.
