pyEntropy GitHub Repo stars PyPI - Downloads

pyEntropy is a lightweight library built on top of NumPy that provides functions for computing various types of entropy for time series analysis.

The library currently supports the following types of entropy computation:

  • Shannon Entropy shannon_entropy
  • Sample Entropy sample_entropy
  • Multiscale Entropy multiscale_entropy
  • Composite Multiscale Entropy composite_multiscale_entropy
  • Permutation Entropy permutation_entropy
  • Multiscale Permutation Entropy multiscale_permutation_entropy
  • Weighted Permutation Entropy weighted_permutation_entropy

Quick Start

Install pyEntropy using pip:

Terminal window
pip install pyentrp

Install pyEntropy using poetry:

Terminal window
poetry add pyentrp


from pyentrp import entropy as ent
import numpy as np
ts = [1, 4, 5, 1, 7, 3, 1, 2, 5, 8, 9, 7, 3, 7, 9, 5, 4, 3]
std_ts = np.std(ts)
sample_entropy = ent.sample_entropy(ts, 4, 0.2 * std_ts)
