Latest Patents

Hung Fuk Lee holds a patent titled "Methods and systems for authorization rate gradual degradation detection." This patent describes systems and methods that utilize modeling techniques to identify gradual changes in various metrics resulting from the analysis of an aggregated transaction dataset. One of the methods involves a computer model that dynamically slices the data using an attribute, calculates an entropy value using a rolling time window, and employs this entropy value to identify anomalous behavior. The model iteratively slices and analyzes the data until it determines a data slice corresponding to the root cause. It also traverses the hierarchy of data slices to combine them into an optimized data slice. Additionally, the model trains a machine learning component, such as a boosted tree algorithm, to enhance its traversal efficiency.
