Published in 2017 at "Journal of Mathematical Chemistry"

DOI: 10.1007/s10910-017-0739-7

Abstract: A perturbation-expansion-at-zero-interval-limit based numeric al algorithm to calculate the eigenpairs of Hilbert–Schmidt integral operators having symmetric kernels is developed in the present work. We have developed the perturbation expansion only for the most dominant eigenvalue… read more here.

Published in 2019 at "International Journal of Machine Learning and Cybernetics"

DOI: 10.1007/s13042-018-0869-7

Abstract: Feature selection is a fundamental preprocess before performing actual learning; especially in unsupervised manner where the data are unlabeled. Essentially, when there are too many features in the problem, dimensionality reduction through discarding weak features… read more here.

Published in 2023 at "Journal of chemical theory and computation"

DOI: 10.1021/acs.jctc.2c01320

Abstract: We apply a global sensitivity method, the Hilbert-Schmidt independence criterion (HSIC), to the reparametrization of a Zn/S/H ReaxFF force field to identify the most appropriate parameters for reparametrization. Parameter selection remains a challenge in this… read more here.

Published in 2019 at "Physical Review A"

DOI: 10.1103/physreva.100.022103

Abstract: The trace distance between two quantum states, $\rho$ and $\sigma$, is an operationally meaningful quantity in quantum information theory. However, in general it is difficult to compute, involving the diagonalization of $\rho - \sigma$. In… read more here.

Published in 2022 at "IEEE Access"

DOI: 10.1109/access.2022.3194926

Abstract: Continuous Compressed-Sensing-Karhunen-Loéve Expansion (CS-KLE) has been proposed. Compressed sensing has been proposed as a highly efficient computational method to represent compressible signals using a few numbers of linear functional. On the other hand, KLE is… read more here.

Published in 2020 at "Filomat"

DOI: 10.2298/fil2014649h

Abstract: We present some inequalities related to the Hilbert-Schmidt numerical radius of 2 x 2 operator matrices. More precisely, we present a formula for the Hilbert-Schmidt numerical radius of an operator as follows: w2(T) = sup… read more here.

Published in 2022 at "Entropy"

DOI: 10.3390/e24030395

Abstract: A witness of non-Markovianity based on the Hilbert–Schmidt speed (HSS), a special type of quantum statistical speed, has been recently introduced for low-dimensional quantum systems. Such a non-Markovianity witness is particularly useful, being easily computable… read more here.
