A Comparison of Empirical Tree Entropies [PDF]

open access: yesLecture Notes in Computer Science, 2020
Whereas for strings, higher-order empirical entropy is the standard entropy measure, several different notions of empirical entropy for trees have been proposed in the past, notably label entropy, degree entropy, conditional versions of the latter two, and empirical entropy of trees (here, called label-shape entropy).

Learning Continuous Decomposable Models Using Mutual Information and Statistical Copulas [PDF]

open access: yesEntropy
Learning dependence graphs from multivariate continuous data is challenging when marginal distributions are heterogeneous, since likelihood-based nonparametric scores can be sensitive to smoothing choices and can confound marginal irregularities ...

Empirical Considerations of Entropy. II. The Entropies of Inorganic Complex Ions [PDF]

open access: yesJournal of Chemical Physics, 1953
A method is proposed by which the partial molal entropies of aqueous complex ions can be correlated in a simple manner as a function of the ratio of their charge to interatomic distance. The agreement obtained between the observed values and those calculated by this method has been shown to be within the accuracy of the experimental data.

Empirical Considerations of Entropy. I. The Entropies of the Oxy‐Anions and Related Species [PDF]

open access: yesJournal of Chemical Physics, 1953
The partial molal entropies for oxy-anions and related species have been correlated as a function of the charge, interatomic distance, and certain structural factors. An equation is given by which the entropy for unknown species can now be estimated fairly accurately.

Dimension-Free Empirical Entropy Estimation

open access: yesIEEE Transactions on Information Theory, 2023
We seek an entropy estimator for discrete distributions with fully empirical accuracy bounds. As stated, this goal is infeasible without some prior assumptions on the distribution. We discover that a certain information moment assumption renders the problem feasible. We argue that the moment assumption is natural and, in some sense, {\em minimalistic} -

Analysis of entropies based on empirical mode decomposition in amnesic mild cognitive impairment of diabetes mellitus [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2015
EEG characteristics that correlate with the cognitive functions are important in detecting mild cognitive impairment (MCI) in T2DM. To investigate the complexity between aMCI group and age-matched non-aMCI control group in T2DM, six entropies combining ...

Effect of d-Dimensional Re-orderings on Lossless Compression of Radio-Astronomy and Digital Elevation Data

open access: yesIEEE Access, 2021
For multidimensional data, Space-Filling Curves (SFCs) have been used to improve the execution time of spatial data queries. However, their effect on compression, when used to reorder the uncompressed values, is known to a lesser extent.

A Robust Machine Learning Model for Diabetic Retinopathy Classification

open access: yesJournal of Imaging, 2023
Ensemble learning is a process that belongs to the artificial intelligence (AI) field. It helps to choose a robust machine learning (ML) model, usually used for data classification.
