Detection of stretch reflex onset based on empirical mode decomposition and modified sample entropy
BMC Biomedical Engineering, 2019 Background Accurate spasticity assessment provides an objective evaluation index for the rehabilitation treatment of patients with spasticity, and the key is detecting stretch reflex onset.

Bounding the expectation of the supremum of an empirical process over a (weak) vc-major class [PDF]
, 2015 Given a bounded class of functions G and independent random variables X1, . . . , Xn, we provide an upper bound for the expectation of the supremum of the empirical process over elements of G having a small variance.

EMPIRICAL COPULAS FOR CDO TRANCHE PRICING USING RELATIVE ENTROPY [PDF]
International Journal of Theoretical and Applied Finance, 2007 We discuss the general optimization problem of choosing a copula with minimum entropy relative to a specified copula and a computationally intensive procedure to solve its dual. These techniques are applied to constructing an empirical copula for CDO tranche pricing.

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

Large Alphabets and Incompressibility
, 2006 We briefly survey some concepts related to empirical entropy -- normal numbers, de Bruijn sequences and Markov processes -- and investigate how well it approximates Kolmogorov complexity. Our results suggest $\ell$th-order empirical entropy stops being a

Copula–entropy theory for multivariate stochastic modeling in water engineering
Geoscience Letters, 2018 The copula–entropy theory combines the entropy theory and the copula theory. The entropy theory has been extensively applied to derive the most probable univariate distribution subject to specified constraints by applying the principle of maximum entropy.
