How to combine labels for deep learning train?

[YunfeiXie]

I am using "Label Objects for Deep Learning" and then used the labels as dataset to train a deep learning model. After the first set of labels and result model, I try to improve the model by labeling more, how can I add the new labels into the old dataset I created before? (combine two sets of labels into one training dataset)

Is it in the "Labelled Objects" section of the help?

Label objects for deep learning—ArcGIS Pro | Documentation

Thank you for the reply. With that section, I'm able to open different sets I labeled, but is there a way to simply combine them together into one file? For example now I have 3 Polygon Feature Classes files containing different set of labels, is it possible to use any tool to combine them into one file so that I can just use that to train a model? 

[DanPatterson]

That is different.  You should combine them first if you want to use the combined results for training

[YunfeiXie]

Now that they are in three files, there is no way to combine them? Do I have to make the labels again together in one round?

[DanPatterson]

are you trying to use 3 separate files to perform the training? (then combine them)

Or, are you trying to apply the training in one file to other files?

that is the difference

I'm currently using 3 separate files to perform training(3 training results) and then merge the result raster, but one of the result is not good so I'm thinking if I can apply the training in one file so that the result can be balanced and improved.
