直观上来讲,一个maximally powerful的GNN将两个节点映射到the same location只有当它们具有相等的subtree structures with identical features on the相关节点。由于subtree structures通过节点邻居循环定义(图1),我们可以将我们对问题的分析简化到whether a GNN maps 2 neighborhoods(i.e. 2 multisets) to the same emb...

Fraud isn’t new—particularly in the financial services industry. Lately, however, we have seen a rise in the sophistication of attacks. To effectively detect and protect against newer, more advanced types of fraud, it’s critical to understand what they are and how they work. ...
start running it. The graph is launched in a session which we can access via thesessvariable. The first thing we do after launching the session is initializing the variables we created earlier. In the variable definitions we specified initial values, which are now being assigned to the ...

As we can see, most of the pictures are realistic enough. We will now get the instance masks, so that we can then train a segmentation model. Getting the labels To get the labels, we will use SAM model to generate masks, and we will then manually filter out masks that are not...
