总共10类,每类几百张照片,val accuracy 在第三轮就达到了1.0,之后一直不变。test accuracy 在前几轮不断上升,上升到第8轮为0.69,之后不断震荡、下降,50轮时,test accuracy 为0.3。loss下降缓慢,到第10轮之后下降的特别特别慢,几乎保持不变。请问楼主,这是什么原因。

这是因为过拟合了,因为你的数据量比较少,而且网络比较复杂,建议换成B1, B2试试。或者你的在进行测试的时候shuffle没有设置为FALSE,导致每次测试都会发生改变。你检查一下哈。
Sorry, something went wrong.
好的,谢谢大佬指点,我试试您的方法,谢谢!
