heoretical question about scaling factors

[AlbertoPresta]

Hi,

first of all congratulations for your paper. it is a remarkable work in my opinion. I have just a question (maybe is a stupid one): how do you get the scaling factors (ai,bi)? are they trainable parameters or not?

Thanks in advance for your answer, Alberto

Thank you for your interest in this work and yes, the scaling factors (a_i and b_i) are all trainable parameters. You may check the code and paper here(https://github.com/tongxyh/ImageCompression_VariableRate) for more details about variable rate learned image compression.
