Some relations between rank, chromatic number and energy of graphs The energy of a graph G, denoted by E (G), is defined as the sum of the absolute values of all eigenvalues of G. Let G be a graph of order n and rank (G) b... SGEZS Akbari - 《Discrete Mathematics》 被引量: ...

The Challenges of Computation on Graphs graph在计算中有三个挑战:lack of consistent structure、node-order equivariance和scalability。 Lack of Consistent Structure graph是极其灵活的数学模型,同时这意味着它们缺乏跨实例的一致结构。比如不同分子之间有不同的结构。用一种可以计算的格式来表示graph并不是一件简单...
需要注意的是1st order proximity和2nd order proximity是分别优化的,当然对于 p_{2}\left(v_{j} | v_{i}\right) 又是一个softmax,我们同样使用负采样优化技术: \log \sigma\left(<\vec{u}_{j}^{\prime}, \vec{u}_{i}>\right)+\sum_{i=1}^{K} E_{\Psi_{n} \sim P_{n}(v)}\left...

In triangle counting, it allows to relabel the graph in upper/lower triangular order. This will greatly improve the performance of the algorithm. To enable relabel-by-degree and relabel the degree of vertices in upper triangular order: $ bench/tc.exe -f karate.mtx --relabel --upper Verifier...
We assume that the system has m phone clones and n hosts. Based on the communication history of phone clones, we can build a communication graph G=〈V,E〉, where V denotes the set of nodes representing the phone clones and E denotes the set of edges representing the communication between...
These higher-order structures play an essential role in the characterization of social networks and molecule graphs. Our experimental evaluation confirms our theoretical findings as well as confirms that higher-order information is useful in the task of graph classification and regression. 展开 ...
