Hey, sorry for a late reply.
If you have a classification model, your output will be an array of values. Check if softmax is included in the network or not, you can easily see this if the values sum up to 1. If they don't, you have to apply softmax operation to the array after you get them out of the network.
Typically, in classification problems, you will take the value that is the highest, and this will be your predicted class. If you want to add some additional thresholding, you can simply check if this confidence value is higher than your threshold. If it's not, you would say that there is no valid prediction.
