Latest Patents

Yini Zhang holds a patent for her invention titled "Machine learning outlier detection using weighted histogram-based outlier scoring (W-HBOS)." This patent describes a method that facilitates different automatic tasks through effective outlier detection in datasets. The process begins with the extraction of an initial set of features from a processed dataset. These features are then filtered using robust statistics to reduce their size. A second round of automatic feature selection is conducted based on maximum-entropy estimation, ensuring that the selected features provide maximum information for detecting anomalies. The chosen features are transformed to generate principal components, which are utilized in the W-HBOS-based model for outlier detection. This method allows for the identification of a subset of outliers, with reason codes determined through back transformation to execute desired automatic tasks.
