Score Threshold

Once you've build your model in Google AutoML, you can look at the model's results in the Evaluate tab. You'll see a slider bar for something called "score threshold". What is this?

The score threshold refers to the level of confidence the model must have to assign a category to a test item.

Precision at value = 1

The notation "precision at value = 1" indicates the precision when a single label is applied to each image.
