Abstract
An analog neuromorphic circuit is disclosed having a first and a second memristor crossbar configuration implemented into an autoencoder. The first memristor crossbar configuration includes resistive memories that provide resistance values to each corresponding input voltage applied to the first memristor crossbar configuration to generate first output voltages that are compressed from the input voltages. The second memristor crossbar includes resistive memories that provide resistance values to each corresponding first output voltage applied to the second memristor crossbar configuration to generate second output voltages that are decompressed from the first output voltages. A controller compares the second output voltages to the input voltages to determine if the second output voltages are within a threshold of the input voltages. The controller generates an alert when the second output voltages exceed the threshold from the input voltages thereby indicating that input data associated with the input voltages has not been previously identified.
