对抗式因果干预证伪

研究问题
生成模型即使拟合观测分布也可能具有错误因果结构,如何通过主动选择干预来证伪模型,并区分干预等价与结构点识别?
方法与思路
作者构建因果生成器与实验者的序贯博弈,以干预索引的判别器比较干预后分布,提出理想与可实施版本及分歧驱动实验设计。
材料陈述的贡献
摘要称在有限模型和干预类中给出最坏干预距离、识别、混合均衡及有限样本保证,并在平衡分离条件下获得对数级淘汰保证。
阅读关注点
应核对可允许干预类、分离条件、分布距离与实际判别器的关系,以及有限类结论、均衡存在和序贯淘汰保证的具体条件。
阅读边界
这是 arXiv 预印本,同行评审或期刊接收未核实。摘要中的理论保证具有明确范围,观测拟合或有限干预通过检验均不自动保证点识别。

原文摘要

Generative models can reproduce an observational distribution while encoding an incorrect causal structure. We study a sequential game in which a structural causal generator proposes observational and interventional distributions, while an adversarial experimentalist selects interventions intended to maximally falsify the generator. The discriminator is therefore not merely a real-versus-synthetic classifier: it is indexed by an intervention and tests whether the generator reproduces the corresponding post-intervention law. We introduce Adversarial Causal Intervention Falsification (ACIF), formulate oracle and implementable versions of the game, and distinguish three objects that are often conflated: observational fit, interventional equivalence over an admissible query class, and point identification of a structural causal model. For finite model and intervention classes, we prove: (i) an exact reduction of the adversarial objective to a worst-intervention integral probability metric; (ii) identification up to interventional equivalence, with point identification under a separating intervention family; (iii) existence of mixed-strategy equilibria; (iv) finite-sample uniform convergence and margin-based model-selection guarantees; and (v) a logarithmic elimination guarantee for a disagreement-driven sequential design under a balanced-separation condition. We also give a complete linear-Gaussian example in which two observationally indistinguishable causal directions are separated by a single well-chosen intervention. The framework clarifies what an adversarial causal discriminator can and cannot certify, and provides a principled bridge between causal generative modeling, active causal discovery, and experimental design.
