# Quick validation Once you have added some initial labels and ran predictions using your labels, a series of tiles appear in the prediction window that might be similar to your chosen labels. In order to quickly assign labels to your predictions, you can select "Quick Validation" at the bottom of the prediction window. Quick validation will step through a series of about 50 tiles in a row, with the same pattern of "observe and label" for each tile. This feature aims to help you focus on assigning labels to individual tiles, without worrying about zooming in to each predicted tile. You can quickly label the predictions and help refine subsequent searches. {% embed url="" %} ### **Entering Quick Validation** Selecting "Quick Validation" launches a separate window to assist with quick labelling, where predicted tiles are sorted into a queue. Earth Index will zoom in directly to the first unlabeled tile, allowing you to closely observe its features.

### **Labelling** If you are able to identify either a positive or negative association, you can select either option to label the tile. To learn about labelling, read this article: [Assigning labels](/concepts/assigning-labels.md) If it is uncertain or confusing how to label, you can click "Skip" to proceed to the next tile. ### **Filter by Confidence** If you want to curate *which* tiles are being shown in this workflow, you can toggle between various levels of "confidence". Confidence suggests how certain our model is that the current tile is very similar to the labeled set of tiles. You can alter the quick validation workflow to show you "High Confidence", "Medium Confidence", and "Low Confidence" tiles.
