INVENTOR: Max Stanford Tomlinson Jr. INVENTION: Spike Transmission for Neural Networks of the INVENTION Pulse trains are utilized for the transmission of information in a neural network. A squash function is acheived by logically OR'ing together pulsed outputs, giving f(?) approximately 1-e-?. For Back Propagation, as derived by Rumelhart, the derivative of the squash function is available by examining the time when no OR'ed together pulses are present, being 1-?(?), or e-?. Logically AND'ing together pulse trains, in certain circumstances, provides the time multiplication of the two signals. Multiplication of input frequencies by weights is accomplished by modulating the width of the output pulses, while keeping the frequency the same. |
