Latest Patents

Zeyu Li holds a patent for a "Method and system for detecting fraudulent transactions using a fraud detection model trained based on dynamic time segments." This patent outlines techniques for detecting fraudulent transactions in a transaction processing system. The method involves receiving a request to process a transaction and generating an input data set that includes a vector representing the transaction alongside historical transaction vectors. The input data set is divided into ragged tensors corresponding to non-overlapping time segments of variable length. A reduced input data set is created by generating representative vectors using max pooling over the vectors in each ragged tensor. Ultimately, a fraudulent transaction score is produced based on this reduced input data set, which informs the processing of the transaction.
