question about module of 'CR optimizer' in Fig.1
trafficstars
Professor, i try to debug your open code. OracleNet can predict the psnr of transmit image, but I don't find the module of 'CR optimizer' in Fig.1.
All in all , I want to know how to use the predicted psnr. In the paper, professor you mentioned that the OracleNet cannot used in other DeepJSCC_V, but when CR is changed will lead to DeepJSCC_V be another one model.
Dear Wen, when we can predict the PSNR, the CR optimization process is actually very easy to be realized because it is a monotonous one-dimensional search problem. When CR changed, the DeepJSCC_V model is still the same as along as its model parameters are the same.
