I've found an article about the Dual Focal loss but not sure it corresponds to the YOLOv8 dfl_loss : Dual Focal Loss to address class imbalance in semantic segmentation Could someone explain to me what is the dfl_loss and how to analyse it ? Thanks ! metrics loss yolov8 Share Improve ...
“dfl损失函数”全称为“数据平均保真度(distributional feature loss)损失函数”,由一项2018年发表的论文《Distributional Feature Learning for FMRI Analysis》提出。它是一种基于密度统计的损失函数,主要用于脑神经影像学的功能磁共振成像(fMRI)分析,可以发现不同功能区域之间的相似性和差异性。 2. “dfl损失函数”的...
Question 4 Correction (Decrease in DFL): A decrease in DFL or any other loss term during training implies the model is improving its predictive ability over epochs. However, DFL does not directly represent the loss between ground truth and predicted values like a traditional bbox loss would, b...
这时候思路就很明显了,要想“软化”这个 loss,就得“软化”θ(x),而软化它就再容易不过,它就是 sigmoid 函数。我们有: 所以很显然,我们将θ(x)替换为σ(Kx)即可: 这就是我昨晚思考得到的 loss 了,显然实现上也是很容易的。 现在跟 Focal Loss Focal Loss Kaiming 大神的 Focal Loss 如果落实到ŷ =...

Search before asking I have searched the YOLOv8 issues and discussions and found no similar questions. Question Hello, I have been looking into the v8DetectionLoss module and I noticed something unexpected in the DFL implementation. Base...
Before using the file:dfl_loss_function.m, please make sure you put this file into the same folder of your main file (where you will be using DFL). Or, if you must put this into a different folder, make sure you add the folder path to the MATLAB path. ...

target_bboxes[bx8400x4](target_bboxes需要缩放到特征图尺度,即除以相应的stride),在计算损失时,分别与预测的pred_bboxes计算CiouLoss, 同时与pred_regs(预测的anchors中心点到各边的距离)计算回归DFL Loss。 c. 训练mask值:fg_mask [bx8400],对8400个anchor进行正负样本标记,计算损失过程中通过fg_mask筛选正...
