Latest Patents

Wang's latest patents include "Trigger point detection for online root cause analysis and system fault diagnosis." This patent describes a computer-implemented method for detecting trigger points to identify root cause failures and fault events. The method involves collecting entity metrics data and system key performance indicator (KPI) data, integrating these data sets, constructing an initial system state space, and detecting system state changes by calculating the distance between current batch data and the initial state. The system status is then divided into different states for better analysis.

Another significant patent is "Incremental causal graph learning for attack forensics in computer systems." This invention provides a method for identifying attack origins by detecting trigger points from entity metrics data and KPI data. It generates a learned causal graph by fusing state-invariant and state-dependent causal graphs. The method includes backtracking from an attack detection point to identify the attack origin and displaying relevant data on a visualization display for user analysis.
