Causal Discovery Algorithms For Time Series Data

[Cho-Geonwoo]

Description:

I am planning to implement various causal discovery methods for time series data. The methods I am particularly interested in include CDAN, ACD, TiMINo, and NTS-NOTEARS. Each of these methods offers unique approaches and advantages for uncovering causal relationships in time series datasets.

Methods of Interest:

CDAN (Causal Discovery with Additive Noise Models)
ACD (Auto Regressive Causal Discovery)
TiMINo (Time Series Interventions with Models for Interventions)
NTS-NOTEARS (Nonlinear Time Series with NOTEARS)
Reference:
For a detailed comparison and discussion of these methods, please refer to the paper available here.

Thank you in advance for your valuable input!

Thank you for your interest in contributing! For now, let's focus on CDAN, ACD, and TiMINo first, as these algorithms fit well into the existing categories in causal-learn (CDAN under constraint-based, ACD under Granger causality-based, and TiMINo under FCM-based). For NTS-NOTEARS, we can consider including it later alongside other continuous optimization methods we are currently working on. What do you think?

Thank you for the guidance! I completely agree with your suggestion. I'll begin by implementing CDAN first and will ensure it aligns well with the existing categories in causal-learn. Looking forward to contributing to this project!
