hyeenna's Introduction

HYEENNA

Hydrologic Entropy Estimators based on Nearest Neighbor Approximations provides estimators for information theoretic quantities as well as a series of algorithms and analysis tools implemented in pure python.

Installation

For now, HYEENNA is only available to install from source. To do so, clone HYEENNA with:

git clone https://github.com/arbennett/HYEENNA.git

Then navigate to the HYEENNA directory and install with:

python setup.py install

Usage

HYEENNA provides nearest neighbor based estimators for

  • Shannon entropy (Single and multivariate cases)
  • Conditional entropy
  • Mutual Information (Diadic and polyadic cases)
  • Conditional Mutual Information
  • KL Divergence
  • Transfer Entropy
  • Conditional Transfer Entropy

Examples

We provide several example notebooks in the notebooks directory.
