ALEXANDRIA, Va., Dec. 9 -- United States Patent no. 12,493,667, issued on Dec. 9, was assigned to International Business Machines Corp. (Armonk, N.Y.).

"Outlier detection in a deep neural network using t-way feature combinations" was invented by Aviad Zlotnick (Mitzpeh Netofah, Israel).

According to the abstract* released by the U.S. Patent & Trademark Office: "Outlier detection using a Deep Neural Network (DNN) includes running a trained DNN model on an received input item. A first feature vector is extracted from the input item and quantized to discrete values. A first number of special t-way feature combinations are computed in the input item and compared against a computed threshold. Based on the comparison, the input item is flagged ...
