Lower Bounds on Mutual Information [PDF]

open access: yes, 2010
We correct claims about lower bounds on mutual information (MI) between real-valued random variables made in A. Kraskov {\it et al.}, Phys. Rev. E {\bf 69}, 066138 (2004). We show that non-trivial lower bounds on MI in terms of linear correlations depend

Achievable information rate optimization in C-band optical fiber communication system

open access: yesFrontiers of Optoelectronics, 2023
Optical fiber communication networks play an important role in the global telecommunication network. However, nonlinear effects in the optical fiber and transceiver noise greatly limit the performance of fiber communication systems.

Reply to "Comment on `Performance of different synchronization measures in real data: A case study on electroencephalographic signals'" [PDF]

open access: yes, 2005
We agree with the Comment by Nicolaou and Nasuto about the utility of mutual information (MI) when properly estimated and we also concur with their view that the estimation based on k nearest neighbors gives optimal results.

Energy and Information Fluxes at Upper Ocean Density Fronts

open access: yesFluids, 2023
We present large eddy simulations of a midlatitude open ocean front using a modified state-of-the-art computational fluid dynamics code. We investigate the energy and information fluxes at the submesoscale/small-scale range in the absence of any ...

Improved Lower Bounds on Mutual Information Accounting for Nonlinear Signal-Noise Interaction [PDF]

open access: yes, 2018
In fiber-optic communications, evaluation of mutual information (MI) is still an open issue due to the unavailability of an exact and mathematically tractable channel model.

Conditional Rényi Divergence Saddlepoint and the Maximization of α-Mutual Information

open access: yesEntropy, 2019
Rényi-type generalizations of entropy, relative entropy and mutual information have found numerous applications throughout information theory and beyond. While there is consensus that the ways A.

Entropy-Based Image Fusion with Joint Sparse Representation and Rolling Guidance Filter

open access: yesEntropy, 2020
Image fusion is a very practical technology that can be applied in many fields, such as medicine, remote sensing and surveillance. An image fusion method using multi-scale decomposition and joint sparse representation is introduced in this paper.

A Novel Nonparametric Feature Selection Approach Based on Mutual Information Transfer Network

open access: yesEntropy, 2022
The filter feature selection algorithm is habitually used as an effective way to reduce the computational cost of data analysis by selecting and implementing only a subset of original features into the study.

Exploiting Multiple Sensory Modalities in Brain-Machine Interfaces [PDF]

open access: yes, 2009
Recent improvements in cortically-controlled brain-machine interfaces (BMIs) have raised hopes that such technologies may improve the quality of life of severely motor-disabled patients.

Organ-focused mutual information for nonrigid multimodal registration of liver CT and Gd–EOB–DTPA-enhanced MRI [PDF]

open access: yes, 2014
Accurate detection of liver lesions is of great importance in hepatic surgery planning. Recent studies have shown that the detection rate of liver lesions is significantly higher in gadoxetic acid-enhanced magnetic resonance imaging (Gd–EOB–DTPA-enhanced
