Specifically, in OHEM each example is scored by its loss, non-maximum suppression (nms) is then applied, and a minibatch is con- structed with the highest-loss examples. The nms threshold and batch size are tunable parameters. Like the focal loss, OHEM puts more emphasis on misclassified ...

Full size image We confirmed by visual inspection that the treatments had the expected impact on both DNA integrity and on filamentous actin, and quantified the γH2AX damage signal and SiR-actin structure (Fig. 2c). Exposure to either 300 nM LatB, 60 μg/ml Zeocin or both for 1...
