I am having a problem comprehending with the relation of kernel, weight and linear separation.
I have a case where I am given a kernel $k_1$. that has a corresponding mapping $\phi_1$. And we know that it's linear separated in that space.
I need to show that given some $a,b > 0$: $$k=a*k_1+b*k_2$$ to show if we have linear separation in the higher dimension.
How do I approach that?
