MATLAB code for dimensionality reduction, feature extraction, fault detection, and fault diagnosis using Kernel Principal Component Analysis (KPCA).
hi,dear. when i use teprocess data. traindata is 52500 and testdata is 96052.
it turns out that Kernel/gaussian (line 86) xy = 2xy';
and how should i put it right ?
我想在我的参考文献里引用你写的论文以示感谢,方便告诉我你的论文吗?
I would like to thank you for quoting your paper in my references. Is it convenient to tell me your paper?
here is error reporting
类 'Kernel' 没有恰当的方法、属性或字段 'width'。

I am so poor in matlab, that i can not debug bymyself .
I will be very grateful to you, if you help me solve this problem .
Hi there,
First of all thanks for the function. On 18 Apr 2019 you've mentioned that DKPCA is added to the code but I cannot seem to find it. Please, would you help me out on how to use it?
Best regards,
Thanks for your great algorithm of KPCA(with Fault Diagnosis). It's owesome to solve the nonlinear problem.
When I rethink the algorithm, I think of that the algorithm belongs to Static KPCA,what if develop a dynamic KPCA method? It seems that there will be a more accurate diagnosis. So I try it.
But I failed to finish it (maybe because I do a wrong thing while making the augmented matrix ).
Sincerely, can you make a further step to realize the algorithm of dynamic KPCA?
Thanks again for your great work!
