Figure 12: Example for x ᵢand what the mapping in the given dimensional vector space would look like Let’s say we would like to calculate f(xᵢ)*f(xᵢ), the dot product in the higher dimensional vector space for xᵢ with itself. You have two options: ▹ Option 1: calculate x in the higher dimension and
