Causal Structure Learning
Causal structure learning aims to discover cause-and-effect relationships between variables from data, often using observational and interventional data to overcome limitations of purely observational studies. Current research emphasizes developing robust algorithms that handle unobserved variables, measurement error, and nonlinear relationships, often employing constraint-based methods, score-based methods, or increasingly, deep learning models like generative adversarial networks (GANs) and graph neural networks. These advancements are crucial for improving the reliability and interpretability of causal inferences across diverse fields, including healthcare, biology, and social sciences, enabling more effective decision-making and scientific discovery.
