In this study, we present a hardware implementation of the conscience mechanism in Kohonen self-organizing maps. The proposed realization of the conscience mechanism is important to the functioning of the neural network as it eliminates so-called dead (inactive) neurons. As a result the network learning, the level quantization error can be reduced. The conscience mechanism and the Winner Take All...

Wireless Sensor Network (WSN) nodes require components with ultra-low power consumption, as they must operate without an external power supply. One technique for reducing consumption of a system is to scale it to a smaller technology; however, in recent technologies is not clear whether the decrease in dynamic power consumption outweighs the increase in static power consumption (due to leakage...
