In this paper, the output reachable estimation and safety verification problems for multi-layer perceptron neural networks are addressed. Again, we will disregard the spatial structure among the pixels (for now), so we can think of this as simply a classification dataset with \(784\) input features and \(10\) classes. The input layer is composed not of full neurons,. ( 1992 ), ‘ A constructive method for multivariate function approximation by multilayer perceptrons ’, IEEE Trans. As the layers and neurons increase, the network structure becomes more complicated compared with a simple neural network and thus capable of solving nonlinear problems.
