Testing Conditional Independence Between Latent Variables by Independence Residuals

Z Chen, J Qiao, F Xie, R Cai, Z Hao… - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
Conditional independence (CI) testing is an important problem, especially in causal
discovery. Most testing methods assume that all variables are fully observable and then test …

Causal Structure Recovery with Latent Variables under Milder Distributional and Graphical Assumptions

XC Li, K Zhang, T Liu - The Twelfth International Conference on …, 2023 - openreview.net
Traditional causal discovery approaches typically assume the absence of latent variables, a
simplification that often does not align with real-world situations. Recently, there has been a …

Learning Discrete Latent Variable Structures with Tensor Rank Conditions

Z Chen, R Cai, F Xie, J Qiao, A Wu, Z Li, Z Hao… - arXiv preprint arXiv …, 2024 - arxiv.org
Unobserved discrete data are ubiquitous in many scientific disciplines, and how to learn the
causal structure of these latent variables is crucial for uncovering data patterns. Most studies …
