Web9 apr. 2024 · 人工神经网络（Artificial Neural Networks，ANN）最早起源于1943年，受“脑神经元学说”的启发，心理学家W·Mcculloch和数理逻辑学家W·Pitts首次提出基于神经元的数学模型，后来经过无数人的改进和完善，一直发展至今，而这发展中间经历了多次低谷，主要原因是当时的计算机算力不足。 Web1. Algorithm Description BP The neural network is a multi -layer network with an input layer, one or more hidden layers, and an output layer. Each neuron on the implicit layer and the output layer corresponds to a stimulating function and a threshold. The neurons on each layer are connected to the neurons on the adjacent layer through weight. WebSet net.trainFcn to 'trainlm'. This will set net.trainParam to trainbr's default parameters.
