You'll have precision, recall, f1-score and support for each class you're trying to find. The recall means "how many of this class you find over the whole number of element of this class". The precision will be "how many are correctly classified among that class".

The consideration of accuracy metric heavily depends on the type of problem. AUC and AP are considered superior metrics compared to the F1 score because of the overall area coverage. troutman office locations https://nhoebra.com

But if your dataset is small, then choosing f-1 score might not give you the best result. Because in small dataset, the accuracy is never the best choice. As f-1 score is the combination between accuracy and AUC score then for small dataset f-1 score might not be the best option.
