About learning rate setting

Hi Yi, How did you decide the lr step ? Did you follow somewhere else or experiment it youself ? Thanks in advance!

Hi, I decided the lr step according to this paper. But usually in my experiments, I just see when the loss/accuracy saturate, and then decay the lr. I find it more effective.

Thanks very much.

Hi Yi I noted that Yuanjun used a batchsize（16x4，16 samples on each card） and iter size 4， so the “batch size” is equal to 256. They used step size 4000, 8000, 10000 （iters） , the corresponding batch steps should be 1000，2000，2500， and epoch number should be about 27，54， 67. Am I right？ Thanks！

Hi, I am so sorry for the slow response, I am at CVPR this week.

I am also using similar strategy iter_size at here. So my corresponding batch steps are still 4000, 8000 and 10000, which is about 100, 200 and 250. Hope this is clear.

Thank you！ Hope you have happy CVPR days！
