Web28 jan. 2024 · IoU Balance Sample Difficult samples have larger loss functions, while easy samples have smaller ones. Difficult samples are essential during sampling because they are more effective at improving detection performance. WebAP Loss [7]. AP Loss is a ranking-based loss function to optimize the ranking of the classification outputs and provides balanced training between positives and negatives. …
