Generation of delayed chaotic neuron with an axisymmetric activation function

This paper addresses generation of delayed chaotic neuron with an axisymmetric activation function. The mathematical model of the proposed system with piecewise-linear (PWL) function is described. An electronic circuitry implementation of this system is also considered in detail. Notably, the proposed PWL circuit unit can also be used as an activation function unit in different systems, such as the famous piecewise function unit of Chua’s diode.
