# Training your classifier

> Train a classifier in FlexiLayout Studio: open the Train Auto Classification Model window, set a profile, adjust precision-recall, and review results.

To begin training your classifier using the document batch to which a layout has been applied, select **Train** in the **Classifier** menu. Then, in the **Train Auto Classification Model** window, set a classification profile and adjust the precision-recall slider if needed. Click **Train**.

Classifier training is performed using reference classes set up during the application of the layout. Classes that are assigned automatically are displayed in the **Classification Result** column. Icons to the left of the page mean the following:
