Spatial Mutual Information as Similarity Measure for 3-D Brain Image Registration

IEEE Journal of Translational Engineering in Health and Medicine, 2014
Information theoretic-based similarity measures, in particular mutual information, are widely used for intermodal/intersubject 3-D brain image registration.

Video Summarization Based on Mutual Information and Entropy Sliding Window Method

Entropy, 2020
This paper proposes a video summarization algorithm called the Mutual Information and Entropy based adaptive Sliding Window (MIESW) method, which is specifically for the static summary of gesture videos.

Reviewing Evolution of Learning Functions and Semantic Information Measures for Understanding Deep Learning

Entropy, 2023
A new trend in deep learning, represented by Mutual Information Neural Estimation (MINE) and Information Noise Contrast Estimation (InfoNCE), is emerging. In this trend, similarity functions and Estimated Mutual Information (EMI) are used as learning and

Two Measures of Dependence

Entropy, 2019
Two families of dependence measures between random variables are introduced. They are based on the Rényi divergence of order α and the relative

Least Dependent Component Analysis Based on Mutual Information [PDF]

, 2004
We propose to use precise estimators of mutual information (MI) to find least dependent components in a linearly mixed signal. On the one hand this seems to lead to better blind source separation than with any other presently available algorithm.

Fuzzy Chance-constrained Programming Based Security Information Optimization for Low Probability of Identification Enhancement in Radar Network Systems [PDF]

, 2015
In this paper, the problem of low probability of identification (LPID) improvement for radar network systems is investigated. Firstly, the security information is derived to evaluate the LPID performance for radar network.

Registration of Brain MRI/PET Images Based on Adaptive Combination of Intensity and Gradient Field Mutual Information

International Journal of Biomedical Imaging, 2007
Traditional mutual information (MI) function aligns two multimodality images with intensity information, lacking spatial information, so that it usually presents many local maxima that can lead to inaccurate registration.

ClearF++: Improved Supervised Feature Scoring Using Feature Clustering in Class-Wise Embedding and Reconstruction

Bioengineering, 2023
Feature selection methods are essential for accurate disease classification and identifying informative biomarkers. While information-theoretic methods have been widely used, they often exhibit limitations such as high computational costs. Our previously

EXIT-charts-aided hybrid multiuser detector for multicarrier interleave-division multiple access [PDF]

, 2010
A generically applicable hybrid multiuser detector (MUD) concept is proposed by appropriately activating different MUDs in consecutive turbo iterations based on the mutual information (MI) gain.

Comparison of co-expression measures: mutual information, correlation, and model based indices

BMC Bioinformatics, 2012
Background Co-expression measures are often used to define networks among genes. Mutual information (MI) is often used as a generalized correlation measure.
