  • Apparatus and method for enhancing transfer function non-linearities in pulse frequency encoded neurons
    Patent number: 5963930
    Abstract: A method and apparatus is presented for synthesizing a network for use with pulse frequency encoded signals that has a smoothly saturating transfer characteristic for large signals based on the use of delay and an OR-gate. When connected to the output of a pulse frequency type of neuron, it results in a sigmoidal activation function.
