Thank you, I recently discovered that my question has a little unfamiliar word.
I’ll add some comment, what I want to mean ‘MOS’ is ‘video quality score’.
Also, After I read your comment, I realized that when the GRU’s second input argument is not defined, GRU is automatically reset as pre-trained state when I loaded first.
So I don’t need to reset GRU when input is changed, because the second input argument is not defined.
Thanks a lot.
