Description

Published in [Thrun et al, 2016] for the case of automatically estimating the radius of the P-matrix. Can also be used to estimate the radius parameter for distance based clustering algorithms.

Usage

1
EstimateRadiusByDistance(DistanceMatrix)

Arguments

DistanceMatrix

[1:n,1:n] symmetric distance Matrix of n cases

Details

For density-based clustering algorithms like DBSCAN it is not always usefull.

Value

Numerical scalar defining the radius

Note

Symmetric matrix is assumed.
