Compressing Images by Encoding Their Latent Representations with Relative Entropy Coding

Neural Information Processing Systems, 2020
Variational Autoencoders (VAEs) have seen widespread use in learned image compression. They are used to learn expressive latent representations on which downstream compression methods can operate with high efficiency.

Signomial and polynomial optimization via relative entropy and partial dualization

Mathematical Programming Computation, 2019
We describe a generalization of the Sums-of-AM/GM-Exponential (SAGE) methodology for relative entropy relaxations of constrained signomial and polynomial optimization problems.

Relative entropy for coherent states in chiral CFT

Letters in Mathematical Physics, 2019
We consider the relative entropy between the vacuum state and a state obtained by applying an exponentiated stress tensor to the vacuum of a chiral conformal field theory on the lightray.

Causation and information flow with respect to relative entropy.

Chaos, 2018
Recently, a rigorous formalism has been established for information flow and causality within dynamical systems with respect to Shannon entropy. In this study, we re-establish the formalism with respect to relative entropy, or Kullback-Leiber divergence,

Newton Polytopes and Relative Entropy Optimization

Foundations of Computational Mathematics, 2018
Certifying function nonnegativity is a ubiquitous problem in computational mathematics, with especially notable applications in optimization. We study the question of certifying nonnegativity of signomials based on the recently proposed approach of Sums ...

Multichannel relative-entropy spectrum analysis

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1986
A new relative-entropy method is presented for estimating the power spectral density matrix for multichannel data, given correlation values for linear combinations of the channels, and given an initial estimate of the spectral density matrix. A derivation of the method from the relative-entropy-principle is given.

Mismatched Estimation and Relative Entropy

IEEE Transactions on Information Theory, 2009
A random variable with distribution P is observed in Gaussian noise and is estimated by a mismatched minimum mean-square estimator that assumes that the distribution is Q, instead of P . This paper shows that the integral over all signal-to-noise ratios (SNRs) of the excess mean-square estimation error incurred by the mismatched estimator is twice the ...

Relative entropy and learning rules

Physical Review A, 1991
The dynamics of a probabilistic neural network is characterized by the distribution \ensuremath{\nu}(x'\ensuremath{\Vert}x) of successor states x' of an arbitrary state x of the network. A prescribed memory or behavior pattern is represented in terms of an ordered sequence of network states ${\mathit{x}}^{(1)}$,${\mathit{x}}^{(2)}$,...,${\mathit{x}}^{(\
