About learning rate setting

[myCigar]

Hello @huochaitiantang

Recently, I retrained the model with your code. The learning rate in the train.sh is 0.00001, and the
default value in the train.py is 0.001. Which learning rate is the one you are using for your current
training model? Thanks !

lr=1e-5 as the paper.

Thanks.

Hi, @huochaitiantang

I am wondering if the training is stable (replicable)? I ran the experiment using the default setting provide by train.sh (except that I change the batchsize to 25), but I got sad=66.7 after epoch 25 and the best sad=60.7 after epoch 5. Do you have any ideas? Thanks!

Current training is sensitive to batch size and the large batch will lead to lower performance. You could get a reasonable result with batch size = 1.

Thanks! I will try a few more experiments (with batch size=1) to see if I could get close to sad=54.42.

Hi, @huochaitiantang

I tried batch size = 1 as you said and got reasonable results from 2 out of 3 experiments. However, I found that the best performance was from Epoch 11 and Epoch 17 respectively and then the sad went up again (more accurately, it was fluctuating at a range 55~70). Were you having the same situation in your experiment? Thanks!

[huochaitiantang]

In my experiment, the sad metric fluctuates at a range 54~64 after the 3rd epoch.

Thanks for your response! I found the same in my experiment.

Hi, thank you for your excellent work!
My question is: why the performance gets worse by increasing the batch size? Does this phenomenon documented in the literature? I am very confusing.
