Comment on Kernel PCA 原理和演示 by wun https://zhanxw.com/blog/2011/02/kernel-pca-%e5%8e%9f%e7%90%86%e5%92%8c%e6%bc%94%e7%a4%ba/#comment-5792 Fri, 26 May 2017 22:54:41 +0000 http://www.zhanxw.com/blog/?p=66#comment-5792 I have one question. When got the ||\alpha^a||_2, how to compute u_a since each element of \alpha_a is unknown.

In other words, the deduction for u_a may lack the variable N.

Thanks for your great efforts.
