Causal DAG
Causal Directed Acyclic Graphs (DAGs) represent causal relationships between variables, aiming to infer the direction of influence from observational or interventional data. Current research focuses on developing efficient algorithms, such as constraint-based methods (e.g., PC algorithm) and those leveraging linear non-Gaussian models (e.g., LiNGAM), to learn these DAGs, often incorporating techniques like GPU acceleration to handle large datasets and addressing challenges posed by heteroscedastic noise and partially known graphs. This field is crucial for advancing causal inference in various domains, enabling more accurate causal effect estimation and fairer machine learning models by accounting for confounding biases and utilizing background knowledge.
