Patent number: 12619684Abstract: A method of detecting anomalies in data, includes receiving a dataset with a plurality of multidimensional data points (MDDPs) wherein a portion of the plurality of MDDPs are labeled and wherein other MDDPs of the plurality of MDDPs are unlabeled; based on a neighborhood size k of the plurality of MDDPs, computing a neighborhood radius ox for each MDDP in a reference dataset computed for the plurality of MDDPs; and generating a locally adaptive similarity (LAS) kernel of a newly arrived MDDP (NAMDDP) based on the neighborhood radius ox. The method additionally includes applying a random walk model to the LAS kernel to determine a probability of the NAMDDP being an anomaly; and if the NAMDDP is an anomaly, outputting data associated with an alarm or notification responsive to the detection of the anomaly.Type: GrantFiled: May 9, 2024Date of Patent: May 5, 2026Assignee: ThetaRay Ltd.Inventors: Amit Bermanis, Amir Averbuch, David Segev

Patent number: 12531885Abstract: Methods that rate (i.e., ranks) the parameters (features) that cause a specific abnormal behavior to occur. It is assumed that the anomalies have already been detected by other anomaly detection methods. A method uses an algorithm based on the underlying potential of the diffusion process that is used in Diffusion Maps to reduce the dimensionality of the data. The gradient of this potential indicates the direction from an anomaly to a cluster that represents a normal behavior. This direction is used to rate the parameters that cause an abnormal behavior to occur.Type: GrantFiled: June 19, 2023Date of Patent: January 20, 2026Assignee: ThetaRay Ltd.Inventors: Amir Averbuch, David Segev
