The Bregman Chord Divergence [PDF]

open access: yes, 2019
Distances are fundamental primitives whose choice significantly impacts the performances of algorithms in machine learning and signal processing. However selecting the most appropriate distance for a given task is an endeavor. Instead of testing one by one the entries of an ever-expanding dictionary of {\em ad hoc} distances, one rather prefers to ...

Minimax quantum state estimation under Bregman divergence [PDF]

open access: yesQuantum, 2019
We investigate minimax estimators for quantum state tomography under general Bregman divergences. First, generalizing the work of Koyama et al. [Entropy 19, 618 (2017)] for relative entropy, we find that given any estimator for a quantum state, there ...

Update of Prior Probabilities by Minimal Divergence

open access: yesEntropy, 2021
The present paper investigates the update of an empirical probability distribution with the results of a new set of observations. The update reproduces the new observations and interpolates using prior information.

Inexact Bregman iteration with an application to Poisson data reconstruction [PDF]

open access: yes, 2013
This work deals with the solution of image restoration problems by an iterative regularization method based on the Bregman iteration. Any iteration of this scheme requires to exactly compute the minimizer of a function.

Neural Bregman Divergences for Distance Learning

open access: yesCoRR, 2022
Many metric learning tasks, such as triplet learning, nearest neighbor retrieval, and visualization, are treated primarily as embedding tasks where the ultimate metric is some variant of the Euclidean distance (e.g., cosine or Mahalanobis), and the algorithm must learn to embed points into the pre-chosen space.

Hessian geometric structure of chemical thermodynamic systems with stoichiometric constraints

open access: yesPhysical Review Research, 2022
We establish a Hessian geometric structure in chemical thermodynamics, which describes chemical reaction networks (CRNs) with equilibrium states. In our setup, the ideal gas assumption and mass action kinetics are not required.

Parametric Bayesian Estimation of Differential Entropy and Relative Entropy

open access: yesEntropy, 2010
Given iid samples drawn from a distribution with known parametric form, we propose the minimization of expected Bregman divergence to form Bayesian estimates of differential entropy and relative entropy, and derive such estimators for the uniform ...

Bregman superquantiles. Estimation methods and applications

open access: yesDependence Modeling, 2016
In thiswork,we extend some parameters built on a probability distribution introduced before to the casewhere the proximity between real numbers is measured by using a Bregman divergence.

Divergence Family Contribution to Data Evaluation in Blockchain Via Alpha-EM and Log-EM Algorithms

open access: yesIEEE Access, 2021
This study interrelates three adjacent topics in data evaluation. The first is the establishment of a relationship between Bregman divergence and probabilistic alpha-divergence.
