Gilles Sadowski ed4817c730 MATH-1548: Remove methods redundant with functionality defined in "NeuronSquareMesh2D". 2020-06-29 00:22:19 +02:00
Gilles Sadowski 28e5b802fe MATH-1548: Move standard quality measures of a SOM into class "NeuronSquareMesh2D". 
All these indicators are usually computed in order to evaluate the quality of a SOM:
Computing them separately is inefficient when the number of samples becomes large.

Gilles Sadowski 67aea22b08 MATH-1535: Recurring issue with method "fixTies" (WIP). 
Current code is too fragile:
 * Adding "jitter" does not work reliably.
 * Changing the seed of the RNG make unit tests fail.

This commit includes:
 * Changing from "MathInternalError" to "MaxCountExceededException".
 * Using named variables for hard-coded values.
 * Adding unit tests (set to "@Ignore" to let the build pass).
 * Handling infinite values to avoid creating NaN values.

Gilles Sadowski bbfe7e4ea5 MATH-1531: Avoid spurious exception. 
In the provided use-case, computation resulted in a value slightly above 1,
thus throwing an exception (invalid probability).
Workaround replaces the value by 1 when it is up to one ULP away.
