The Rate-Distortion-Perception Trade-off: The Role of Private Randomness

arXiv:2404.01111v1 Announce Type: cross
Abstract: In image compression, with recent advances in generative modeling, the existence of a trade-off between the rate and the perceptual quality (realism) has been brought to light, where the realism is measured by the closeness of the output distribution to the source. It has been shown that randomized codes can be strictly better under a number of formulations. In particular, the role of common randomness has been well studied. We elucidate the role of private …
