System and method for cognitive processing for data fusion

Abstract

A system and method for cognitive processing of sensor data. A processor array receiving analog sensor data and having programmable interconnects, multiplication weights, and filters provides for adaptive learning in real-time. A static random access memory contains the programmable data for the processor array and the stored data is modified to provide for adaptive learning.

AI Technical Summary

Benefits of technology

The present invention is a system and method for processing sensor data using a processor array with programmable interconnects, multiplication weights, and filters. The system can adaptively learn in real-time, and a static random access memory can store the programmable data for the processor array. The method involves receiving sensor data, applying a set of multiplicative weights to the data, filtering the data based on a set of filter characteristics, and outputting the data after a second set of weights is applied. The technical effects of this invention include improved accuracy and efficiency in processing sensor data, as well as adaptive learning in real-time.

Problems solved by technology

One draw back of the Von Neumann architecture is that it is slow, regardless of computer speed.

To deal with complex data fusion applications as required in military applications, particularly remote, real time applications related to the dynamic environment, the Von Neumann machine may not be effective for demands such as compactness, real time processing, adaptive system and low power.

The speed requirements may present a challenge for a digital computer and the architecture of a system as a whole.

Each sequential step requires a delay and processing time to digest data, and finally, the solution that is provided by the computer may no longer be valid.

However, neural network hardware is typically not as fully-programmable as a digital computer.

A neural network hardware implementation also has a two-fold problem: reliable learning techniques in limited weight space for learning network convergence in a parallel architecture (see, for example, T. A. Duong and Allen R. Stubberud, “Convergence Analysis Of Cascade Error Projection—An Efficient Learning Algorithm For Hardware Implementation,” International Journal of Neural System, Vol. 10, No. 3, pp.
