我的损失很大,一般都在万以上,这样会不会造成梯度爆炸呢? 我的做法:
1 输入:下载了BSDBS500数据,使用原图和二值图标签训练,使用源代码中的方法,没有归一化输入,只是减每个通道均值 2 中间处理:模型超参数使用代码原始的参数,没有修改,batch 1 iter 10 lr 1-e6 3 输出:损失1w-2w,图相train文件夹里除了第一个有轮廓其他都是黑的或灰的,test文件夹下根本没有轮廓 希望有成功运行的人,能指点一下正确的处理过程,多谢! 1输入 2中间处理 3输出

我解决了这个问题 1 输入: wget http://mftp.mmcheng.net/liuyun/rcf/data/bsds_pascal_train_pair.lst wget http://mftp.mmcheng.net/liuyun/rcf/data/HED-BSDS.tar.gz 下载后我截取了前3k个数据 2 中间: 使用代码原始参数,一些打印的参数可以改改,lr和iter和batchsize的都用原始的 3 输出: 损失开始从1k多几个epoch后到300左右,输出的轮廓图接近的样例了
Sorry, something went wrong.
请问你最后F值是多少呢?
