“Fault-tolerance or graceful degradation is the property that enables a system (often computer-based) to continue operating properly in the event of the failure of (or one or more faults within) some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naïvely-designed system in which even a […]

Following the way learning is performed, we can distinguish two major categories of neural networks:  fixed networks in which the weights cannot be changed, ie dW/dt=0. In such networks, the weights are fixed a priori according to […]

In other words, a nonlinear system is any problem where the variable(s) to be solved for cannot be written as a linear combination of […]
