If it is impossible to direct edges of the given graph in such a way that the obtained directed graph does not contain paths of length at least two, print "NO" in the first line. Otherwise print "YES" in the first line, and then printany suitable orientation of edges: a binary string...
Specifically, comparing the embedding quality with and without reverse mapping and fine-tuning. We anticipate, however, that on the entity classification task, such a comparison would not be indicative of the extent to which information is regained in this step. This is because entity classification...
This algorithm is used to construct a directed graph with the same reachability and satisfies transitive closure, with as few edges as possible. More concretely, it creates a minimum equivalent graph with as few edges as possible, removing "short-circuit" paths through the graph. ...

Such directed graphs without cycles are called directed acyclic graphs or DAGs. DAGs are powerful tools used to model combinational circuits, and we will dig deeper into their properties in the following subsections. In some applications, we can assign values to the edges so that a graph can ...
For the new node, its embedding representation is generated directly without the need to learn again. Furthermore, a novel adversarial regularized framework is proposed for graph embedding in [92]. Then we introduce the GCN models. GCN extends the convolution operation from traditional data (such ...
In most cases, only the chemical structure of molecules is generated, i.e., the connectivity of the molecular graph, without additional information on specific 3D geometry. Initial graph generative models were designed to generate graphs based on simplified theoretical assumptions, such as the random...
scalability, maintainability, safety, and ethics. Ideally, the system should enable seamless integration of new devices, resources, and algorithms without disrupting the system’s overall functioning. It is also critical to allow for dynamic adaption to changes in research goals and resource restrictions...
