In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

尽管基于卷积神经网络（CNN）的方法在处理图像等规则网格上定义的输入数据方面表现出色，研究人员逐渐意识到，具有不规则拓扑的视觉信息对于表示学习至关重要，但尚未得到彻底研究。与具有内在连接和节点概念的自然图数据（如社交网络）相比，从规则网格数据构建图缺 ...
