Question



Support Vector Machines and figure 2.15

In figure 2.15 Case 4, the cross product is raised to the power 'n.' I thought 'n' was the dimensionality of the input space - however, in
the example directly below figure 2.15 the input space has 3 dimensions (c1, c2, c3) and the cross product is raised to the 2 power in case
4. What am I missing?

Answer or follow-up question 1

Dear student,

I not entirely sure on what you are asking.
Please note that (a+b)^2 results in a^2, b^2, and 2ab. That is why there are three dimensions.
If this does not answer your question, please elaborate.
