Research Type Experimental In this section, we evaluate the performance of the proposed AKBR model against state-of-the-art graph kernels and deep learning methods. We use ten standard graph datasets extracted from bioinformatics (Bio), social networks (SN), and computer vision (CV). The OGBG-MOLBACE and OGBG-MOLBBBP datasets are selected from Open Graph Benchmark [Hu et al., 2020]. The Shock dataset can be obtained from [Siddiqi et al., 1999]. Other datasets from bioinformatics and social networks can be directly downloaded from [Morris et al., 2020]. We provide the graph number and the average graph size of each dataset in Table 1. Experimental results show that the proposed AKBR model outperforms existing state-of-the-art graph kernels and deep learning methods on standard graph benchmarks.
