Explore the concept of K-Connected Graphs in Graph Theory, their properties, and significance in graph connectivity.
如果边的总数小于可能边的总数 ((N x (N-1))/2),那么这个图是稀疏(sparse)的,否则就是稠密(dense)的。 有向图(Directed Graph) && 无向图(Undirected Graph) 有向图中,edge is also called acrs 入度(in-degree) && 出度(out-degree) 路径(Path) 如果在之间存在一条从 u 到 x 路径 p,则称 x ...
Higher-rank graph C*-algebras were introduced in 2000 by Kumjian and Pask. They are natural generalizations of directed graph algebras and many of the results concerning higher-rank graphs have come by finding higher-rank analogs of results from the theory of directed graph algebras.Shotwell, ...
In graph theory, a regular graph is a graph where each vertex has the same number of neighbors; i.e. every vertex has the same degree or valency. A regular directed graph must also satisfy the stronger condition that the indegree and outdegree of each vertex are equal to each...

K-最近邻(KNN)是一种非参数监督式分类模型。它可以根据计算k个训练样本到查询点(query point)的距离(主要是欧几里德距离和马哈拉诺比斯距离)来分配标签(单独为每个点计算)。它在协同过滤推荐系统中有广泛的应用。 基本思想 训练样本是多维特征空间向量,其中每个训练样本带有一个类别标签。算法的训练阶段只包含存储的...
We construct a spectral sequence for computing KR-theory, analogous to the spectral sequence relating motivic cohomology to algebraic K-theory. D Dugger - K-Theory 被引量: 99发表: 2003年 Algebraic $K$-theory of toric hypersurfaces We construct classes in the motivic cohomology of certain 1-pa...
In theory, the K-algorithm can work with any cost function. In practice, there are a few constraints. First, the delta of a given node should be calculated quickly without looping through the entire dataset. Second, the optimal value for a cost function should produce k non-empty clusters ...
For k≥5, we follow the method that has been already successful for Theorem 1.1, Theorem 1.2: studying the structure of a graph that does not contain the desired tree. It turns out that, in most cases, the structure is simple. Note that the proofs in the present work are independent ...
Our main result is that MCS can be used to bound the performance from above and below of a more complex sub-graph scheduling algorithm, known as Maximal Independent Graph Scheduling (MIGS), which in many cases does not have a known explicit construction. 展开 ...
