High-speed motorized spindle heating will produce thermal error, which is an important factor affecting the machining accuracy of machine tools. The error model high-speed spindles can compensate for and improve effectively. In order to confirm high precision model, Beetle antennae search algorithm (BAS) proposed optimize prediction based on BP neural network. Through characteristic experiment,...

A general problem in model selection is to obtain the right parameters that make a model "t observed data. For a multilayer perceptron (MLP) trained with back-propagation (BP), this means "nding appropiate layer size and initial weights. This paper proposes a method (G-Prop, genetic backpropagation) that attempts to solve that problem by combining a genetic algorithm (GA) and BP to train MLPs w...

This paper proposes a new version of a method (G-Prop-III, genetic backpropaga-tion) that attempts to solve the problem of nding appropriate initial weights and learning parameters for a single hidden layer Mul-tilayer Perceptron (MLP) by combining a genetic algorithm (GA) and backpropagation (BP). The GA selects the initial weights and the learning rate of the network, and changes the number o...
