Introduction

Xiaotong Liu is a prominent inventor based in San Jose, California. He has made significant contributions to the field of technology, particularly in the area of anomaly detection within IT environments. With a total of 10 patents to his name, Liu's work is recognized for its innovative approaches to performance monitoring and log anomaly detection.

Latest Patents

One of Liu's latest patents focuses on performance monitoring in the anomaly detection domain for the IT environment. This approach retrieves a set of current system data from a computer system and outputs from an anomaly detection model that monitors the system. The data and model outputs are processed by a trained anomaly detection supervisor model, which provides performance data. If the performance data indicates that the anomaly detection model is underperforming, adjustments are made accordingly.

Another notable patent involves log anomaly detection in continuous artificial intelligence for IT operations. This method includes a computer receiving a windowed log of incoming raw log messages. The computer compares statistical distribution metrics of entities in the log with a real-time statistical model. If discrepancies are found, the log is tagged as an entity anomaly. Additionally, the computer computes a distance between an average word embedding vector in the log and a statistical distribution from the model. If this distance exceeds a predetermined threshold, the log is tagged as a word embedding anomaly, and an alert is sent to the user indicating the severity of the anomaly.
