Graph masked attention
WebSep 20, 2024 · We developed a novel molecular graph augmentation strategy, referred to as attention-wise graph masking, to generate challenging positive samples for … Webmask in graph attention (GraphAC w/o top-k) in TableI. Results show that the performance without the top-k mask degrades in core semantic metrics, i.e., CIDE r, SPICE and SPIDE r. Examples of their adjacency graphs (bilinear inter-polated) are shown in Fig.2(c)-(f). The adjacency graph gen-
