GeneratePmatrix | R Documentation |
Generates a P-matrix too visualize only density based structures of high-dimensional data.
Data |
[1:n,1:d], A |
EsomNeurons |
[1:Lines,Columns,1:Weights] 3D array of weights given by ESOM or sESOM algorithm. |
Radius |
The radius for measuring the density within the hypersphere. |
PlotIt |
If set the Pmatrix will also be plotted |

If set the Pmatrix will also be plotted |
To set the Radius the ABCanalysis of high-dimensional distances can be used [Ultsch/Lötsch, 2015]. For a deteailed definition and equation of automated density estimation (Radius) see Thrun et al. 2016.
