A Method of Jadeite Jade Appraisal Based on Neural Networks

It is quite subjective by the ordinary method to determine the weighting factor of the price for jadeite jade.However, the disturbance of the subjective factor could be effectively ruled out by the neural network method.A three-layered Back-Propagation network model being a multi-factor comprehensive evaluation of the price for jadeite jade is constructed.The prices of the jadeite jade samples from a jewelry shop of China University of Geosciences(Wuhan) have been evaluated comprehensively.The experimental results show that the appraisal for jadeite jade by the neural network method is convenient, true and calculable.
