PD-RPEB: Heterogeneous Static-Graph Risk Propagation Evaluation and Blocking for Power Distribution Operations

IEEE Access
Risk control in power distribution operations is critical for grid security and personnel safety, but static local rules and prediction-oriented models have limited ability to represent multi-factor coupling, risk propagation, tracing evidence, and ...

Computing Personalized PageRank Using Strongly Connected Components in Web

, 2010
網頁排序是搜尋引擎中一項重要的排序技術。藉由不同的個人化向量，搜尋引擎公司可以為不同群組的使用者計算出特殊及適合的網頁排序向量。然而，僅計算單一網頁排序向量便需花費許多時間。為了解決這個問題，我們提出了SCC (Strongly Connected Component)網頁排序演算法。SCC 網頁排序演算法的主要精神在於利用舊的網頁排序向量推導出新的網頁排序向量。我們將網頁排序模組中原先的線性系統拆解為線性子系統。利用這些線性子系統間的相依關係，我們將原本的計算轉變為階層式架構 ...
