Gilles commented on MATH-1270:
------------------------------
Visualization of quantization error implemented in commits:
* 7929e10a8f8bbb43672b4a695b68a1e1fd8ad40e (3.6)
* 924e1e9064f90d958b4f57e9c9c0c543bd19dcfb (4.0)
> SOFM: Implement various visualization algorithms
> ------------------------------------------------
>
> Key: MATH-1270
> URL: https://issues.apache.org/jira/browse/MATH-1270
> Project: Commons Math
> Issue Type: Wish
> Reporter: Gilles
> Assignee: Gilles
> Priority: Minor
> Fix For: 4.0, 3.6
>
>
> There are various ways for visualizing the properties of a SOFM:
> * U-matrix
> * Topographic error
> * Hit histogram
> * Smoothed data histograms
> * ...
> Some are currently implemented in {{MapUtils}}, but they should be defined in
> their own class, implementing interfaces proposed in MATH-1268.
