Random Walk Conformer: Learning Graph Representation from Long and Short Range

نویسندگان

چکیده

While graph neural networks (GNNs) have achieved notable success in various mining tasks, conventional GNNs only model the pairwise correlation 1-hop neighbors without considering long-term relations and high-order patterns, thus limiting their performances. Recently, several works addressed these issues by exploring motif, i.e., frequent subgraphs. However, methods usually require an unacceptable computational time to enumerate all possible combinations of motifs. In this paper, we introduce a new GNN framework, namely Random Walk Conformer (RWC), exploit global correlations local patterns based on random walk, which is promising method discover structure. Besides, propose walk encoding help RWC capture topological information, proven more expressive than spatial encoding. Extensive experiment results manifest that achieves state-of-the-art performance classification regression tasks. The source code available at https://github.com/b05901024/RandomWalkConformer.

Random walk with long - range constraints ∗

We consider a model of a random height function with long-range constraints on a discrete segment. This model was suggested by Benjamini, Yadin and Yehudayoff and is a generalization of simple random walk. The random function is uniformly sampled from all graph homomorphisms from the graph Pn,d to the integersZ, where the graph Pn,d is the discrete segment {0, 1, . . . , n} with edges between v...

Entropy of Random Walk Range

We study the entropy of the set traced by an n-step simple symmetric random walk on Z. We show that for d ≥ 3, the entropy is of order n. For d = 2, the entropy is of order n/ log n. These values are essentially governed by the size of the boundary of the trace.

Fast Random Walk Graph Kernel

Random walk graph kernel has been used as an important tool for various data mining tasks including classification and similarity computation. Despite its usefulness, however, it suffers from the expensive computational cost which is at least O(n) or O(m) for graphs with n nodes and m edges. In this paper, we propose Ark, a set of fast algorithms for random walk graph kernel computation. Ark is...

On Exact Learning from Random Walk

We consider a few particular exact learning models based on a random walk stochastic process, and thus more restricted than the well known general exact learning models. We give positive and negative results as to whether learning in these particular models is easier than in the general learning models.
