In this letter, we propose a visibility graph (VG)-based adjacency matrix representation of LS in conjunction with a residual deep neural network (ResNet) for accurate detection of COPD, namely, the ...

To maximize the homogeneity of these two distinct graphs, we design an improved semi-supervised contrastive loss. In order to enrich scarce label information, we propose a self-supervised mechanism to ...

Learn the three steps you can take to get in the Knowledge Graph (and trigger a knowledge panel for your brand) without a Wikipedia article.

Discover explicit formulae for the number of 7-cycles and total cycles of lengths 6 and 7 containing a specific vertex in a simple graph. Explore the role of adjacency matrix and combinatorics in this ...
