Abstract:

During this period improvements have been made in the pulse coded neuron which realizes all 16 binary valued logic functions of two inputs. Because the original circuit is inconvenient for VLSI, a study has been made of how to delete the filters used in the previously reported neuron. From this we have been led to a new pulse coded neuron which shows promise for realizing any Hopfield tyoe of neural network in the pulse coded framework. At this point the new pulse coded neuron has been shown to allow us to also generate 14 of the 16 binary valued logic functions without the use of the inconvenient filters of the previous pulse coded neuron. Also using the new neuron a two input MAXNET has been realized. A major problem in implementing Hopfield types of neural networks in the pulse coded philosophy is how to encode general weights. A promising technique to solve this problem is under investigation.
