Error Visualization Scenarios
Scenario Type Detail
Saving errors into CSV file Basic Path It is possible to save errors into comma-delimited file .csv.
Errors from ErrorList written into the file and then saved (function BP_ErrorVisul.B_Save_Click() )
Showing errors Basic Path In the Window, there are two important parts
- Data-Grid with number of step and error in that step
- Graph of Error Function

Data-Grid is simple filled from BP_Network.ErrorList and so is the Graph. The graph class is used from external dll DasNetBarChart.dll
Structure for Network error Basic Path During the training, in function BP_Network.StepTrainNet(...) - in each training cycle, the value of global error function is noted into class ErrStep. Class ErrStep contains only number of actual cycle and actual error. Newly created object is then inserted into ArrayList BP_network.ErrorList.

Every BP_network has its ArrayList for noting errors.
