We consider the problem of recovering the causal structure underlying observations from different experimental conditions when the targets of the interventions in each experiment are unknown. We assume a linear structural causal model with additive Gaussian noise and consider interventions that perturb their targets while maintaining the causal relationships in the system. Different models may entail the same distributions, offering competing causal explanations for the given observations. We fully characterize this equivalence class and offer identifiability results, which we use to derive a greedy algorithm called GnIES to recover the equivalence class of the data-generating model without knowledge of the intervention targets. In addition, we develop a novel procedure to generate semi-synthetic data sets with known causal ground truth but distributions closely resembling those of a real data set of choice. We leverage this procedure and evaluate the performance of GnIES on synthetic, real, and semi-synthetic data sets. Despite the strong Gaussian distributional assumption, GnIES is robust to an array of model violations and competitive in recovering the causal structure in small- to large-sample settings. We provide, in the Python packages "gnies" and "sempler", implementations of GnIES and our semi-synthetic data generation procedure.

在关键安全应用中，当没有可解释的解释时，从业者不愿信任神经网络。许多尝试提供此类解释的尝试围绕基于像素的属性或使用先前已知的概念。在本文中，我们旨在通过证明\ emph {高级，以前未知的地面概念}来提供解释。为此，我们提出了一个概率建模框架来得出（c）插入（l）收入和（p）rediction（clap） - 基于VAE的分类器，该分类器使用可视上可解释的概念作为简单分类器的预测指标。假设是基本概念的生成模型，我们证明拍手能够在达到最佳分类精度的同时识别它们。我们对合成数据集的实验验证了拍手确定合成数据集的不同基础真相概念，并在医疗胸部X射线数据集上产生有希望的结果。

我们研究了因果结构学习的问题，没有关于功能关系和噪声的假设。我们开发DAG-Foci，这是一种基于\ Cite {Azadkia2019Simple}的焦点变量选择算法的计算快速算法。DAG-Foci不需要调整参数并输出父母和Markov边界的响应变量的响应变量。当底层图形是多料时，我们提供了我们程序的高维保证。此外，我们展示了DAG-Foci在计算生物学\ Cite {Sachs2005Causal}的真实数据上的适用性，并说明了我们对侵犯假设的方法的稳健性。
