图11. 根据支持向量机(SVM)和反向传播神经网络(BPNN)计算的奥氏体体积分数(fv)、奥氏体相内C的质量分数(fm)及拉伸性能与疲劳强度的平均相关系数(R2)

Fig.11. Mean values of correlation coefficient (R2) between the volume fraction of austenite (fv), mass fraction of C consumed by austenite (fm) and tensile properties (YS—yield strength, TS—tensile strength, EL—elongation) and fatigue strength calculated by support vector machine (SVM) (a) and back-propagation neural network (BPNN) (b) with training test random 100 times
