1. In Workbench, create .ega file for SOM classification - using data: http://dione.zcu.cz/~toman40/encog/data7.zip - and set "Maximum Error Percent (0-100)" = 10.
2. Excecute "task-full".
3. Create ``data7_eval.egb`` by "Normalize to Training(EGB)" action.
4. Double click ``data7_train.eg``, click "Train", set "Training Set" = data7_train.egb and "Validation Set (optional)" = data7_eva.egb and select "Basic... Training".
5. Run the training again -> "Validation Error" will be ~7.5 %, but there is only ~50 % of correctly classified rows in ``data7_output.csv`` (where ``y``=``Output:y``).
