Device for high dimensional computing comprising an associative memory module

A computer program product for high-dimensional computing, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a control unit to perform a method comprising:

• programming profile vector elements of a plurality of profile hypervectors as conductance states of a plurality of resistive memory elements in a plurality of crossbar arrays, wherein the profile vector elements of respective ones of the profile hypervectors are programmed in different ones of the crossbar arrays;
• applying query vector elements of a query hypervector as read voltages to the profile vector elements programmed in the crossbar arrays;
• performing a distance computation between each of the profile hypervectors and the query hypervector by measuring output current signals output by the crossbar arrays upon the application of the query vector elements;
• and
• making a selection based on the distance computation.

A high-dimensional computing device comprising:

• an associative memory module comprising at least two crossbar arrays configured to store respective profile hypervectors;
• and
• an encoding module configured to receive an input, determining a query hypervector based on the input, and apply the query hypervector to each of the at least two crossbar arrays,
• wherein the associative memory module is configured to determine, according to a distance computation and a based on an application of the query hypervector to each of the at least two crossbar arrays, which of the profile hypervectors is most similar to the query hypervector.
