3) Recall the Gaussian Kernel for an SVM: $K(x^{(i)}, x^{(j)}) = exp\left( - \frac{||x^{(i)} - x^{(j)}||^2}{2\sigma^2} \right)$. Suppose we have three points, $z_1$, $z_2$ and $x$. $z_1$ is geometrically very close to $x$, and $z_2$ is geometrically far away from $x$. What is the value of $K(z_1, x)$ and $K(z_2, x)$? [1]
