Specifically, we introduce a novel graph kernel based on the k-dimensional Weisfeiler-Lehman algorithm. Unfortunately, the k-dimensional Weisfeiler-Lehman algorithm scales exponentially in k.

On bounded-degree graphs, it can even be computed in constant time. In this article, we propose a family of efficient kernels for large graphs with discrete node labels. Key to our method is a rapid feature extraction scheme based on the Weisfeiler-Lehman test of isomorphism on graphs. Abstract. Using concepts from the Weisfeiler-Lehman WL test of isomorphism, we propose a mixed WL graph kernel MWLGK framework based on a family of efficient WL graph kernels for constructing mixed graph kernel. Key to our approach is the Weisfeiler-Lehman test of isomorphism, which allows us to compute a sequence of graphs which capture the topological and label information of the original graph in a runtime which is linear in the number of edges. We can apply existing graph kernels on this graph sequence and make them take into account the structural information which they ignored before.

Weisfeiler-Lehman kernel. Section 3 formulates the graph similarity search problem, and derives a new bound to reduce the search to a semi-conjunctive query. In Section 4, our search algorithm is presented without using wavelet trees. In Section 5, a wavelet tree is integrated to our algorithm for optimal succinctness. Section 6 reports experimental results and we conclude the paper in Section. grades the Weisfeiler-Lehman and other graph kernels to effectively exploit high-dimensional and continuous vertex at-tributes. Graphs are ﬁrst decomposed into subgraphs. Vertices of the subgraphs are then compared by a kernel that com- bines the similarity of their labels and the similarity of their structural role, using a suitable vertex invariant. By changing this invariant we obtain a. The Weisfeiler–Lehman graph kernel exhibits competitive performance in many graph classiﬁ-cation tasks. However, its subtree features are not able to capture connected components and cycles, topological features known for character-ising graphs. To extract such features, we lever-age propagated node label information and trans- form unweighted graphs into metric ones. This permits us to.

It is not discussed why the edge information was used for the Weisfeiler-Lehmann graph kernel. There have been link prediction approaches which ignore the predicate so that a comparison of the exclusion of the edge information could be interesting.
