What is a kernel method? I know what an operating system kernel is. I know what the kernel of a homomorphism is. I have taken courses in computational statistics and neural networks. Yet I’ve never encountered this use of the word kernel, which the article unhelpfully does not define (yet is critically based on). Googling for kernel didn’t help either, because the term is extremely overloaded.
I guess an intuitive way to approach it given your background is by learning SVMs and how the kernel method is used to do non-linear classification. Or start with wiki article, https://en.m.wikipedia.org/wiki/Kernel_method
Can someone help?
