Title: Innovations of Inventor Kai Shen

Introduction

Kai Shen is an accomplished inventor based in Apex, North Carolina. He has made significant contributions to the field of anomaly detection through his innovative patents. With a total of three patents to his name, Shen's work focuses on advanced methodologies for identifying anomalies in data streams.

Latest Patents

One of his latest patents is titled "Real-time anomaly detection and mitigation for streaming functional data." This invention involves accessing functions that represent sequences of values from a time-series dataset. It computes a discretized covariance function to analyze relationships within a current time window. By performing eigenanalysis, Shen estimates eigenfunctions and increments the time window to compute a second covariance function. The angle change between normalized eigenfunctions is then used to generate an anomaly detection output.

Another notable patent is "Anomaly detection using RPCA and ICA." In this invention, a computing device identifies anomalies among observation vectors by projecting them using a predefined orthogonal complement matrix. This matrix is derived from a low-rank matrix computed through a robust principal component analysis algorithm. The projected observation vector is then demixed using an independent component analysis algorithm, leading to the computation of a detection statistic value that indicates the presence of an anomaly.
