use variance of the distribution of angles \(\left\langle p_1-o, p_2-o\right\rangle\) to any two neighbors \(p_1\) , \(p_2\)
can use the kernel trick (like SVMs) for angles in a virtual high-dimensional [...] *{Var}_{x,y \in D \atop x,y \neq o} \frac{\langle x-o, y-o\rangle }{\textup{dist}(o,x)^2\cdot \textup{dist}(o,y)^2}\]
For high-dimensional data!
