Causal discovery

Causal discovery is the process of inferring causal relationships between variables from observational data. This repository aims to provide a collection of causal discovery algorithms implemented in Python.

Development setup

This repository uses Poetry as a dependency manager. To install the dependencies, run:

$ poetry install

Usage

You can install the package from PyPI:

$ pip install causal-discovery

example usage:

from causal_discovery.algos.notears import NoTears

# load dataset
dataset = ...  

# initialize model
model = NoTears(
    rho=1, 
    alpha=0.1, 
    l1_reg=0, 
    lr=1e-2
)

# learn the graph
_ = model.learn(dataset)

# adjacency matrix
print(model.get_result())
