Fault-tolerant MLP networks for improved reliability and safety

Presents a modified multi-layer perceptron (MLP) network called the modular redundant MLP (MR-MLP) network that shows improved reliability and safety. The standard MLP is first augmented by duplicating the hidden units and then the output module is duplicated m times to give an m MR-MLP. The outputs of the MR-MLP network are processed by voting circuits that produce the final outputs of the system together with a flag that indicates the validity of the output vector
