二度方程
The model Contrasts the remove second-degree polynomial regression equation that established. The results show that, the neural network method has a higher accuracy and much smaller error and more parallel processing capacity.
与本文建立了剔除法二次多项式回归方程对比,结果表明BP网络在拟合时精度更高、误差更小同时并行处理能力更强。
A curve or surface whose equation ( in Cartesian coordinates) is of the second degree. The circular points are really a degenerate conic.
方程式是二次方程式的曲线或表面。虚圆点实际上是一退化的二次曲线。
