Abstract
In this contribution, a new loss function is defined where quantization parameter is used as a factor for the loss calculation in the training stage. In this study, the intra models from NCS-1.0 with NN filter set 1 are retrained using the latest published scripts. BD-rate changes of {Y, Cb, Cr} are summarized as follows:
