Analysis and Application of Steel Harden Ability Forecasting Model Based on Support Vector Machine

Harden ability is a heat treat property of steel. Harden-ability is mainly determined by chemical composition and organization structure of steel. Support vector machine is a novel machine learning method, which is powerful for the problem characterized by small sample, nonlinearity, high dimension and local minima, and has high generalization. In this paper, harden-ability of steel based on support vector machine is proposed and compared with neural network. Theoretical and simulation analysis indicate that the support vector machine model is better in performance
