Requirements

• Python 3.6+
• numpy
• scipy
• python-igraph
• torch

Running NOTEARS(-MLP) with ADMM

• See examples/linear.ipynb and examples/nonlinear.ipynb for a demo in the linear and nonlinear cases, respectively.

Acknowledgments

• A large part of the code, including some helper functions, is obtained and modified from the implementation of NOTEARS, and we are grateful to the authors of NOTEARS for releasing their code.
• The code to post-process the output is modified and obtained from the implementation of GOLEM.
