Exclude a class from solution training to prevent the model from ever making predictions for a particular output field class. For example, you can exclude a particular incident category from training if you plan to retire or change the category.

## Antes de Iniciar

Role required: admin or ml_admin

## Por Que e Quando Desempenhar Esta Tarefa

Excluding a class from training doesn't prevent the solution from making predictions
for records that use the excluded class. Solution training still uses the input and
output field values as data and attempts to match input field values to a new output
field class. This attempt may cause undesirable prediction results unless you have
another suitable class to replace the excluded class value.

Typically, you only exclude a class from training if you change the list of valid
output field values. For example, if you replaced one incident category with another
incident category, you may exclude the old category from training so that the
solution only uses the new category for predictions.  
Nota:  
If you specify a target recall for a class, don't exclude the class from training even if the number of records are less than 30 for that class.

## Procedimento

1. Navigate to AllPredictive IntelligenceClassificationSolution Definitions.  
   The system shows the current list of solution definitions.
2. Select the solution definition you want to edit.  
   For example, select Incident Categorization to exclude an incident category from training.
3. Edit the filter to exclude the class.  
   You can use the \[is one of\] or \[is not one of\] operators to exclude a particular class.  
   For
   example, if you want to exclude the Hardware class, add this condition:
   \[Category\] \[is not one of\] \[Hardware\].
4. Click Update \& Train.  
   The system schedules the solution for training with the nearest training service. When training is complete, the system uploads the solution as an Attachment record.

## Resultado

The solution excludes the class from all predictions.

## O que Fazer Depois

Review the trained solution precision and coverage statistics.
