dist.fun.inverse

The function is used as distance-dependent weight \(w\) for k-NN voting.

A topological version of k-NN: An abstract model is build
as 2-dimensional self-organising map. Samples of unknown
class are predicted by mapping them on the SOM and analysing
class membership of neurons in the neighbourhood.
