much brighter output image of my trained weights than the one produced by the released weights #17

Thanks for share the implementation.

When I use the model which was trained myself following the training step, my output images were quite bright (at ~30th epoch).

Do you have any idea for possible reason?

Appreciate.

You may change the learning rate to 10-5 or change the value of exposure loss to 0.5 or 0.45. The results are related to the training data. So, if you change the training datasets, the configurations may need to be changed. Thanks.

Hi, Li,

Thank you for quick reply.
I understand the 2nd solution.
But why and how does the learning rate affect the output brightness?

Thank you again.

Hunt
