According to the formative mechanism of white residue and the feature of data, the hypothesis testing method of statistical analysis is adopted to increase the data reliability. The knowledge representation of production is introduced into the system, and the expert system of data classification is built based on the principal component analysis and the accumulation of the empirical knowledge. Then, the neural network is designed to predict the accurate value of the white residue. At last, it is simulated by the computer. The simulation result shows that the neural network of hypothesis testin...
