NATURAL LANGUAGE PROCESSING WITH KNN

A system for natural language processing includes a memory array and a processor. The memory array is divided into a similarity section storing a plurality of feature vectors, a SoftMax section in which to determine probabilities of occurrence of the feature vectors, a value section storing a plurality of modified feature vectors, and a marker section. The processor activates the array to perform parallel operations in each column indicated by the marker section: a similarity operation in the similarity section between a vector question and feature vectors stored in indicated columns; a SoftMax operation in the SoftMax section to determine an associated SoftMax probability value for indicated feature vectors; a multiplication operation in the value section to multiply the associated SoftMax value by modified feature vectors stored in indicated columns; and a vector sum in the value section to accumulate an attention vector of output of the multiplication operation.
