离散因果表示学习

研究问题
如何从连续、计数和二元等混合观测中恢复大量离散潜变量之间的因果结构,同时保持表示的可解释性与理论保证?
方法与思路
作者构建离散潜变量 DAG 与稀疏潜在—观测二部图,采用灵活测量模型,并依次进行惩罚估计、潜状态重采样和评分式因果发现。
材料陈述的贡献
摘要称,在其所述温和条件下,两层图可由观测分布识别,三阶段程序具有一致性,并在教育测评和合成图像中展示稀疏结构。
阅读关注点
应核对所谓温和条件、图结构识别的具体含义、潜变量标记不确定性,以及重采样误差如何影响后续因果发现的一致性。
阅读边界
这是 arXiv 预印本,同行评审及期刊接收均未核实;摘要未列出识别与一致性的具体条件,也未提供有限样本保证。

原文摘要

Causal representation learning seeks to uncover causal relationships among high-level latent variables from low-level, entangled, and noisy observations. Existing approaches often either rely on deep neural networks, which lack interpretability and formal guarantees, or impose restrictive assumptions like linearity, continuous-only observations, and strong structural priors. These limitations particularly challenge applications with a large number of discrete latent variables and mixed-type observations. To address these challenges, we propose discrete causal representation learning (DCRL), a generative framework that models a directed acyclic graph among discrete latent variables, along with a sparse bipartite graph linking latent and observed layers. This design accommodates continuous, count, and binary responses through flexible measurement models while maintaining interpretability. Under mild conditions, we prove that both the bipartite measurement graph and the latent causal graph are identifiable from the observed data distribution alone. We further propose a three-stage estimate-resample-discovery pipeline: penalized estimation of the generative model parameters, resampling of latent configurations from the fitted model, and score-based causal discovery on the resampled latents. We establish the consistency of this procedure, ensuring reliable recovery of the latent causal structure. Empirical studies on educational assessment and synthetic image data demonstrate that DCRL recovers sparse and interpretable latent causal structures.
