Introduction

Jonathan L. Herlocker is an accomplished inventor based in Seattle, WA. He holds a total of seven patents, showcasing his expertise in the field of anomaly detection and time series analysis in physical systems. His innovative approaches have significantly contributed to advancements in technology.

Latest Patents

One of his latest patents is a method for physical system anomaly detection. This method generates a set of candidate physics models from a set of physics rules and a process graph representing the system. It assigns physics rules to portions of the process graph that represent sensors. Candidate physics models are rejected if the error between the models and sensor data exceeds a predetermined error tolerance. Supervised learning is employed to train a machine learning model to predict the error between the physics models and the sensor data. The predicted error and predicted sensor measurements from the physics models are then utilized to detect anomalies using unsupervised learning on a distribution of error between the predicted sensor measurements and the sensor data.

Another significant patent involves the analysis of time series sensor measurements in physical systems. This method retrieves sensor data streams from stored sensor time series data. Each sensor data stream comprises a sequence of time-value pairs and is associated with a sensor identifier, a time offset, and a sampling period. A metric data stream is produced from the retrieved sensor data streams in accordance with a stored physics model of the physical system. Producing the metric data stream includes synchronizing the sensor data streams by adjusting time offsets and adding interpolated values to create synchronized streams with equal sampling periods. Additionally, a point-wise computation is performed over the values of the sensor data streams in accordance with the physics model.
