...的分布式賬本技術正在被探索和應用當中。有向無環圖(Directed Acylic Graph,以下簡稱DAG)是其中的代表之一。 DAG技術以及它背后的設計思想是什么?實際應用效果如何?我們嘗試通過對DAG技術進行深層解析以及對代表性項...
DAG(有向無環圖) 有向無環圖,directed acyclic graphs,簡稱DAG,是一種圖的數據結構,其實很naive,就是沒有環的有向圖_(:з」∠)_ DAG在分詞中的應用很廣,無論是最大概率路徑,還是后面套NN的做法,DAG都廣泛存在于分詞中。 ...
...示節點之間的關系,若關系是有方向的,則圖為有向圖(directed graph),此時圖中的邊有箭頭。若關系沒有方向,則圖為無向圖(undirected graph),此時圖中的邊沒有箭頭,直接相連的節點互為鄰居。如上圖是有向圖,Rama是Alex的鄰居。 ...
