WebNov 10, 2024 · $\begingroup$ This is a very good and exhaustive answer. The bit where you identify the causal effect through the front-door is, however, superfluous (OP has already done it and it follows straight from the front-door theorem), and it also contains a mistake: There is no "law of total probability" for causal effects.

WebGraph Neural Networks (GNNs) have demonstrated their powerful capability in learning representations for graph-structured data. Consequently, they have enhanced the performance of many graph-related tasks such as node classification and graph classification. However, it is evident from recent studies that GNNs are vulnerable to …
WebIn the following graph, conditioning on X1 and X2, or SAT and family income, is sufficient to close all backdoor paths between the treatment and the outcome. In other words, \((Y_0, Y_1) \perp T X1, X2\). So even if we can’t measure all common causes, we can still attain conditional independence if we control for measurable variables that ... phil vs wash nflWebFeb 11, 2024 · Though there are some initial efforts in graph backdoor attacks, our empirical analysis shows that they may require a large attack budget for effective backdoor attacks and the injected triggers can be easily detected and pruned.
