I have the following averaged $precision-recall$ curves with $4$ models. Which one is the best?
As there's no much difference given that the scale on the y-axis doesn't start from zero, the difference between the models in the graph seem exaggerated than normal.
It would be best to go by taking a decision of favoring recall vs precision. If you would rather have a false positive and try and catch more of the target(better recall), then Model 2(lowest precision, highest recall). If its the other way around, then Model 3.
