WebAs you can see, the overall F1-score depends on the averaging strategy, and a macro F1-score of less than 0.33 is a clear indicator of a model's deficiency in the prediction task. EDIT: Since the OP asked when to choose which strategy, and I think it might be useful for others as well, I will try to elaborate a bit on this issue. WebF1-Score (F-measure) is an evaluation metric, that is used to express the performance of the machine learning model (or classifier). It gives the combined information about the precision and recall of a model. This means a high F1-score indicates a high value for both recall and precision. Generally, F1-score is used when we need to compare two ...
