“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...
3)调整ppyoloe_r_crn.yml文件 loss_weight中dfl权重,dfl_loss值从1.0下降到0.8,但仍存在训练到一定程度dfl_loss不下降问题 部分训练过程如下: arning: Unable to use numba in PP-Tracking, please install numba, for example(python3.7):pip install numba==0.56.4 Warning: Unable to use numba in PP-Tr...
@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:...
"Regarding dfl_loss, it stands for "distribution focal loss", which is a variant of focal loss that helps improve model performance when training data is imbalanced. Specifically, distribution focal loss is used to deal with class imbalance that arises when training on datasets with very rare ob...
软化loss 硬截断会出现不足,关键地方在于因子 λ(y,ŷ) 是不可导的,或者说我们认为它导数为 0,因此这一项不会对梯度有任何帮助,从而我们不能从它这里得到合理的反馈(也就是模型不知道“保持”意味着什么)。 解决这个问题的一个方法就是“软化”这个 loss,“软化”就是把一些本来不可导的函数用一些可导函数...
loss[1] = self.bce(pred_scores,target_scores).sum()/target_scores_sum 其中预测pred_scores: b x 8400 x cls_num; target_scores: b x 8400 x cls_num, 相当于对于每个box,其cls_num个分类都视为二分类,并进行交叉熵运算。 (2) 边框回归损失 边框回归,采用的是DFL Loss + CIOU Loss target_b...
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. ...

Distribution Focal Loss (DFL) is indeed utilized in YOLOv8. It is a modified version of the traditional Focal Loss which was originally created for addressing class imbalance in object detection tasks. However, in YOLOv8, we deploy DFL in the context of bounding box regression. DFL is not ...
