Characterization of the Distortion-Perception Tradeoff for Finite Channels with Arbitrary Metrics

no code implementations3 Feb 2024 Dror Freirich, Nir Weinberger, Ron Meir

We provide a structural characterization of the DP tradeoff, where the DP function is piecewise linear in the perception index.

A Theory of the Distortion-Perception Tradeoff in Wasserstein Space

no code implementations NeurIPS 2021 Dror Freirich, Tomer Michaeli, Ron Meir

In this paper, we derive a closed form expression for this distortion-perception (DP) function for the mean squared-error (MSE) distortion and the Wasserstein-2 perception index.

Distributional Multivariate Policy Evaluation and Exploration with the Bellman GAN

no code implementations6 Aug 2018 Dror Freirich, Ron Meir, Aviv Tamar

In this formulation, DiRL can be seen as learning a deep generative model of the value distribution, driven by the discrepancy between the distribution of the current value, and the distribution of the sum of current reward and next value.
