Latest Patents

Zekun Xu holds a patent titled "Local outlier factor hyperparameter tuning for data outlier detection." This invention involves a computing device that determines hyperparameter values for outlier detection. The process includes computing an LOF score for observation vectors using a neighborhood size value. Outlier observation vectors are selected, and their mean and variance values are computed. Inlier observation vectors are also identified, and a difference value is calculated using the outlier and inlier statistics. The method is repeated for various neighborhood sizes to select the optimal value associated with an extremum of the difference value. This patent showcases his expertise in enhancing data analysis techniques.
