  kernel pcr
The number of components used in the case of kernel PLS is on average 10 times lower when compared to kernel PCR.
      
Kernel PCR and kernel RR are briefly described in Section 5.
      
In some cases kernel PLS uses less than 10% of the number of components used by kernel PCR.
      
In the nonlinear case, on average, univariate kernel PLS uses less than 80% of the components used by kernel PCR.
      
However, in comparison to kernel PCR, the kernel PLS method uses a much smaller number of qualitatively different components.

With regard to the limitations of kernel PCR with single kernel,mixtures of kernels principal component regression(PCR) is proposed to improve the generalization ability and nonlinearity.Mixtures of kernels are characterized by more global and local ability.The influence of different kernels can be turned by parameter to combine the prior knowledge in the determination of the kernels,which makes this method more suitable for different applications.Soft sensor modeling using this method to acrylonitrile process has shown that the method is superior to other methods,and meets the demands of field application better.

针对核函数PCR方法中单个核函数的局限性,提出了混合核函数PCR方法并将其用于工业过程软测量建模,以提高模型的推广能力和非线性处理能力。混合核函数集中了多个核函数的特点,兼具局部和全局特性,并可以通过参数调节他们对混合核函数的作用,将过程的先验知识融入到核函数的确定,进而适合不同的应用。工业丙烯腈生产过程丙烯腈收率软测量建模的应用表明,基于混合核函数PCR的软测量模型要优于核函数PCR方法,满足了工业应用要求。

Principles of kernel-based methods and two kernel-based statistical modeling techniques are introduced. Soft sensor modeling of selectivity to acrylonitrile using kernel PLS and kernel PCR is proposed to cope with the nonlinearity and multi high dimension of input and collinearity problem of process. It is found that the performance of kernel-based methods is superior to linear statistical model and that of kernel PLS is also superior to kernel PCR.
