WebImplementation for focal loss in tensorflow. This focal loss is a little different from the original one described in paper. This one is for multi-class classification tasks other than binary classifications.. The input are softmax-ed probabilities. WebFocal Loss. Focal Loss was proposed by Tsung-Yi Lin et al. in order to improve one-stage object detector. This loss down-weight the loss value of well classified targets. So, this loss allow to detector learn from the hard-example well. This loss has potential for expansion into other task such as classification or semantic segmentation.
