Latest Patents

Steven holds a patent titled "Anomaly detection using RPCA and ICA." This invention involves a computing device that identifies anomalies among a plurality of observation vectors. The process begins with projecting an observation vector using a predefined orthogonal complement matrix, which is determined from a decomposition of a low-rank matrix. This low-rank matrix is computed using a robust principal component analysis algorithm. The projected observation vector is then multiplied by a predefined demixing matrix to define a demixed observation vector. This demixing matrix is computed using an independent component analysis algorithm along with the predefined orthogonal complement matrix. A detection statistic value is computed from the defined, demixed observation vector. If this computed detection statistic value meets or exceeds a predefined anomaly threshold value, an indicator is output, signaling that the observation vector is an anomaly. Steven's innovative approach has the potential to significantly improve anomaly detection processes across various applications.
