Convincing Causal Analysis using a DAG and Backdoor Path Criterion

WebFeb 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. Therefore, in this paper, we study a novel problem of unnoticeable graph backdoor attacks with limited attack … WebGraph Trojaning Attack (GTA) which also uses subgraphs as triggers for graph poisoning. But unlike Subgraph Backdoor [50], GTA learns to generate adaptive subgraph structure for a specific graph. Different from Subgraph Backdoor and GTA, GHAT learns to generate pertur-bation trigger, which is adaptive and flexible to different graphs.

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. WebWe can close back door paths by controlling the variables on those back door paths. We can do that by statistically holding these variables constant.
