Limit your classification model to use only the most common classes when training. You can specify the number of classes to use.

## Before you begin

Role required: ml_admin or admin

## About this task

Restricting the model to a fixed number of the most frequent labels improves focus and performance, especially with large datasets.

You can add this option in the solution definition form by using the following procedure. Alternatively, you can use a script to add this option.

To add this option using a script:  

    config.setTopNLabels(100);

In JSON format:  

    {
        "include_top_n_labels": 100
        }

## Procedure

1. To add this option in the solution definition form, navigate to AllPredictive IntelligenceClassificationSolution Definitions.
2. Open an existing classification solution or create a new one.
3. Select the Advanced Solution Settings tab in the Related Links section of the form.
4. Select New to open the Advanced Solution Setting (ml_advanced_solution_settings) form.
5. In the Solution Parameters field, search for <kbd class="ph userinput">include only top n labels</kbd>.
6. In the User Inputs field, enter the number of classes you want as the limit, then select Submit.  

## Result

The setting appears as a row on the Advanced Solution Setting tab on your solution's form.

## What to do next

Retrain your solution.
