我做的两个类别(fire,smoke),loss_bbox: 0.0000 loss_dfl: 0.0000一直为0,百思不得其解,有没有高手给指点一下,非常感谢。
@tm924222, could you provide me a sample annotation file?嗨,你能给我一个示例注释文件吗? 我也遇到了这个问题,但我的loss_cls一开始很大但一个epoch后就变成0了,loss_box和loss_dfl一直是0 wondervictor commentedon May 23, 2024 wondervictor on May 23, 2024 Collaborator @Unicorn123455678@tm924222这种...
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 =...
“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...
if self.use_dfl: target_ltrb = self.bbox2reg(anchor_points, target_bboxes, self.reg_max) loss_dfl = self._df_loss(pred_regs[fg_mask].view(-1, self.reg_max + 1), target_ltrb[fg_mask]) * weight ---原理分析--- 提问:采用的是交叉熵运算,为什么是交叉熵运算呢? 因为DFL...
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. References: [1] Hossain,...
@文心快码epoch gpu_mem box_loss cls_loss dfl_loss instances size 文心快码 在深度学习训练过程中,特别是在目标检测任务中,如使用YOLO(You Only Look Once)框架时,我们经常会遇到一些特定的输出指标,如epoch、gpu_mem、box_loss、cls_loss、dfl_loss、instances和size。下面我将逐一解释这些术语的含义: Epoch:...
