“…Because of its powerful feature representation ability, it has received great attention in the fields such as computer vision and natural language processing [6,7,8]. Text, images, and videos are all data defined on a regular grid, which can be viewed as distributed on one -, two -, and three-dimensional grid support sets [9,10,11,12,13]. Graph convolutional networks have attracted more and more attention by using their powerful feature representation ability to improve learning effects.…”
