IDTxl

The Information Dynamics Toolkit xl (IDTxl) is a comprehensive software package for efficient inference of networks and their node dynamics from multivariate time series data using information theory. IDTxl provides functionality to estimate the following measures:

1. For network inference:
   • multivariate transfer entropy (TE)/Granger causality (GC)
   • multivariate mutual information (MI)
   • bivariate TE/GC
   • bivariate MI
2. For analysis of node dynamics:
   • active information storage (AIS)
   • partial information decomposition (PID)

IDTxl implements estimators for discrete and continuous data with parallel computing engines for both GPU and CPU platforms. Written for Python3.4.3+.

To get started have a look at the wiki and the documentation. For further discussions, join IDTxl's google group.
