Generalized Mutual Information [PDF]

open access: yesStats, 2020
Mutual information is one of the essential building blocks of information theory. It is however only finitely defined for distributions in a subclass of the general class of all distributions on a joint alphabet.

An Axiomatic Characterization of Mutual Information

open access: yesEntropy, 2023
We characterize mutual information as the unique map on ordered pairs of discrete random variables satisfying a set of axioms similar to those of Faddeev’s characterization of the Shannon entropy.

Mutual information bounded by Fisher information

open access: yesPhysical Review Research
We derive a general upper bound to mutual information in terms of the Fisher information. The bound may be further used to derive a lower bound for the Bayesian quadratic cost. These two provide alternatives to other inequalities in the literature (e.g.,

Mutual information rate and bounds for it. [PDF]

open access: yesPLoS ONE, 2012
The amount of information exchanged per unit of time between two nodes in a dynamical network or between two data sets is a powerful concept for analysing complex systems.

Error Exponents and α-Mutual Information

open access: yesEntropy, 2021
Over the last six decades, the representation of error exponent functions for data transmission through noisy channels at rates below capacity has seen three distinct approaches: (1) Through Gallager’s E0 functions (with and without cost constraints); (2)

Finite Sample Based Mutual Information

open access: yesIEEE Access, 2021
Mutual information is a popular metric in machine learning. In case of a discrete target variable and a continuous feature variable the mutual information can be calculated as a sum-integral of weighted log likelihood ratio of joint and marginal density ...

The kernel mutual information [PDF]

open access: yes2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004
We introduce a new contrast function, the kernel mutual information (KMI), to measure the degree of independence of continuous random variables. This contrast function provides an approximate upper bound on the mutual information, as measured near independence, and is based on a kernel density estimate of the mutual information between a discretised ...

Estimating mutual information [PDF]

open access: yesPhysical Review E, 2004
We present two classes of improved estimators for mutual information $M(X,Y)$, from samples of random points distributed according to some joint probability density $μ(x,y)$. In contrast to conventional estimators based on binnings, they are based on entropy estimates from $k$-nearest neighbour distances.

Mutual Information and Multi-Agent Systems

open access: yesEntropy, 2022
We consider the use of Shannon information theory, and its various entropic terms to aid in reaching optimal decisions that should be made in a multi-agent/Team scenario.

Mutual information for fermionic systems

open access: yesPhysical Review Research, 2022
We study the behavior of the mutual information (MI) in various quadratic fermionic chains, with and without pairing terms and both with short- and long-range hoppings.
