训练过程中准确率一直没有变化 #12
Comments
嗯,我也遇到这个问题,目前在排查中。。 |
我怀疑这个论文是不是有问题,我尝试了很多修改loss都没法下降。 |
我有一个疑问,在你提取数据的时候,你将annotations.csv提取为正标签,将candidates_V2.csv提取为负标签,您是否注意到candidates_V2.csv文件中已经包含了annotations.csv的全部标签 |
loss不收敛代码在交叉熵使用的时候有个错误: |
@jieshaoxxiansen 你说的我倒真没注意到,我以为candidates_v2.csv全部是负样本标签呢。感谢提醒。 |
在每个ct图像上我取了100个反例,跑了1000个epoch,准确率一直是0.593750,loss也一直基本没有什么变化。请问是什么问题呢?您试验的效果怎么样
