Latest Patents

Vickey Chang's latest patents include "Evaluation of modeling algorithms with continuous outputs" and "Interactive model performance monitoring." The first patent addresses the evaluation of modeling algorithms whose outputs can influence machine-implemented operating environments. It describes a computing system that generates a discretized evaluation dataset by comparing estimated attribute values to validation attribute values. This system computes an evaluation metric for the modeling algorithm and provides access to this metric and modeling outputs to a host computing system, facilitating modifications to machine-implemented operations.

The second patent, "Interactive model performance monitoring," involves automated performance monitoring of statistical models. It utilizes a processing device to perform statistical analysis on archived information, extracting historical data, scores, and attributes. The device calculates performance metrics based on this data and pre-calculates summary performance data, which is stored in a non-transitory, computer-readable medium. Users can interactively access segmented data through a graphical user interface (GUI), enhancing the usability of the performance monitoring system.
