fastseriation

fastseriation is a Python package that can be used to seriate matrices.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

To get the code you will need git. To install git on Ubuntu use the following commands in a terminal

sudo apt update
sudo apt install git

To clone the repository from github use the following command in a terminal

git clone https://github.com/avramidis/fastseriation.git

To run the code you will need Python version 3, to install it use the following command in a terminal

sudo apt install python3

Installing

To install fastseriation package use the following command in a terminal

python3 setup.py install

Example

An example code that uses fastseriation is the following

import matplotlib.pyplot as plt
import numpy
import fastseriation.seriate

scores = numpy.zeros((100, 10))
for i in range(100):
    for j in range(10):
        scores[i, j] = abs(i - j)

plt.figure()
plt.imshow(scores, cmap='brg', interpolation='nearest', aspect='auto')
plt.show(block=False)

per = numpy.random.permutation(100)
scores_permutation = scores[per, :]

seriated_indexes = fastseriation.seriate.seriate(scores_permutation)

plt.figure()
plt.imshow(scores_permutation[seriated_indexes, :], cmap='brg', interpolation='nearest', aspect='auto')
plt.show(block=False)
