Title: Innovations by Xinyi Zhang
Introduction
Xinyi Zhang is an accomplished inventor based in San Jose, CA. She has made significant contributions to the field of data analysis and anomaly detection, holding a total of 6 patents. Her work focuses on developing advanced systems and methods for detecting changes in time series data.
Latest Patents
Xinyi's latest patents include innovative techniques such as Non-parametric change point detection. This patent describes systems, mediums, and methods for simultaneously determining multiple types of changes in time series data. A plurality of potential change points may be selected in a signal representing the time series data. For each potential change point, the signal may be split into two segments, including data points before and after the potential change point. An estimate of the cumulative distribution function for each segment may be determined, and a normalized difference of the respective estimates may be compared to a threshold value to identify valid change points.
Another notable patent is related to statistics-based anomaly detection. This patent outlines systems and methods for detecting anomalies in a discrete signal, where samples correspond to data flow amounts in a network within a time interval. The discrete signal is received, and a sequence of likelihoods corresponding to the sample values is generated based on a historical probability distribution. Likelihood change points are identified, and segments are analyzed to determine if they qualify as anomalies.
