...的分布式账本技术正在被探索和应用当中。有向无环图(Directed Acylic Graph,以下简称DAG)是其中的代表之一。 DAG技术以及它背后的设计思想是什么?实际应用效果如何?我们尝试通过对DAG技术进行深层解析以及对代表性项...
DAG(有向无环图) 有向无环图,directed acyclic graphs,简称DAG,是一种图的数据结构,其实很naive,就是没有环的有向图_(:з」∠)_ DAG在分词中的应用很广,无论是最大概率路径,还是后面套NN的做法,DAG都广泛存在于分词中。 ...
...示节点之间的关系,若关系是有方向的,则图为有向图(directed graph),此时图中的边有箭头。若关系没有方向,则图为无向图(undirected graph),此时图中的边没有箭头,直接相连的节点互为邻居。如上图是有向图,Rama是Alex的邻居。 ...
