采用360万数据集,其他参数和你的一致,不管是 从头训练还是finetune最后正确率都在50左右震荡是怎么回事

可以先保存模型,换个learning rate

这些参数是我加了我自己生成的数据finetune的参数,如果你有条件,batch size 大一点会更好

你是说降低学习率不断调试吗?
还有就是我看你的github下又多出一部分datagenerator,你是在调参的时候还加了数据?

@haneSier

嗯,这个 data generator 是将模型调到我自己应用场景加的数据

@haneSier

嗯嗯对,标签和图片路径

我在训练的时候,只要设置一个合适的学习率(当时我用的应该是0.001),loss能降到2左右,然后再换小一点的

https://github.com/Sierkinhane/crnn_chinese_characters_rec/blob/master/test_images/4.png 这是我刚才跑了一下代码的结果,

有加上自己的

嗯嗯,在原来模型跑的,主要是看个效果,

没有,第一个是每隔几样本显示一次,第二个是每隔多少步验证一次
