Construction of a programmable multilayer analogue neural network using space invariant interconnects

摘要

Abstract: A programmable multilayer neural network is under construction to illustrate the advantages of optical interconnects (scaleability, bandwidth) and to overcome the disadvantages of optical devices (limited precision, nonideal transfer characteristics, lack of subtraction). The disadvantages will be surmounted with the help of dedicated software engineering and additional optical hardware. The complete system design is summarized, and the construction of the first matrix vector multiplier subunit is detailed together with first test results. Finally, the progress made on the remaining subunits is reported with a perspective to future work. !6
