A Self-Adaptive Synthetic Over-Sampling Technique for Imbalanced Classification
Xiaowei Gu, Plamen P Angelov, Eduardo Almeida Soares
Traditionally, in supervised machine learning, (a significant) part of the available data (usually 50% to 80%) is used for training and the rest for validation. In many problems, h…
Orbital stability of solitary waves for the generalized Choquard model
Vladimir Georgiev, Mirko Tarulli, George Venkov
We consider the generalized Choquard equation describing trapped electron gas in 3 dimensional case. The study of orbital stability of the energy minimizers (known as ground states…
On the extraction of power-law parts of the probability density functions in star-forming clouds
Todor V. Veltchev, Philipp Girichidis, Sava Donkov +5
We present a new approach to extract the power-law part of a density/column-density probability density function (rho-pdf/N-pdf) in star-forming clouds. It is based on the mathemat…
Indicating Asynchronous Multipliers
P Balasubramanian, D L Maskell, N E Mastorakis
Multiplication is a basic arithmetic operation that is encountered in almost all general-purpose microprocessing and digital signal processing applications, and multiplication is p…
Master equation for operational amplifiers: stability of negative differential converters, crossover frequency and pass-bandwidth
T. M. Mishonov, V. I. Danchev, E. G. Petkov +5
The time dependent master equation from the seminal article by Ragazzini, Randall and Russell [J. R. Ragazzini, R. H. Randall and F. A. Russell, "Analysis of Problems in Dynamics b…
Decay and Scattering in energy space for the solution of weakly coupled Schrödinger-Choquard and Hartree-Fock equations
Mirko Tarulli, George Venkov
We prove decay with respect to some Lebesgue norms for a class of Schrödinger equations with non-local nonlinearities by showing new Morawetz inequalities and estimates. As a bypro…
