Fast Piecewise Polynomial Fitting of Time-Series Data for Streaming Computing

IEEE Access, 2020
Streaming computing attracts intense attention because of the demand for massive data analyzing in real-time. Due to unbounded and continuous input, the volume of streaming data is so high that all the data cannot be permanently stored.

ASSESSING AND FORECASTING THE STATE OF DETERIORATING SYSTEMS WITH THE USE OF MODIFIED REGRESSION POLYNOMIALS ON THE BASIS OF FUNCTIONAL APPROXIMATION OF THEIR COEFFICIENTS

Сучасні інформаційні системи, 2023
Object of research is technical state of deteriorating systems whose operating conditions depend on a large number of interacting factors. The caused inhomogeneity of the sample of initial data on the technical state leads to impossibility of correct ...

Semidefinite relaxations for semi-infinite polynomial programming [PDF]

, 2013
This paper studies how to solve semi-infinite polynomial programming (SIPP) problems by semidefinite relaxation method. We first introduce two SDP relaxation methods for solving polynomial optimization problems with finitely many constraints.

Model Order Selection From Noisy Polynomial Data Without Using Any Polynomial Coefficients

IEEE Access, 2020
Given a set of noisy data values from a polynomial, determining the degree and coefficients of the polynomial is a problem of polynomial regressions. Polynomial regressions are very common in engineering, science, and other disciplines, and it is at the ...

Probabilistic small-signal stability analysis of power systems based on Hermite polynomial approximation

SN Applied Sciences, 2021
This paper proposes a probabilistic small-signal stability analysis method based on the polynomial approximation approach. Since the correct determination of unknown coefficients has a direct effect on the accuracy of the polynomial approximation method,

Mean Square Polynomial Stability of Numerical Solutions to a Class of Stochastic Differential Equations

, 2014
The exponential stability of numerical methods to stochastic differential equations (SDEs) has been widely studied. In contrast, there are relatively few works on polynomial stability of numerical methods.

Numerical Polynomial Homotopy Continuation Method and String Vacua

Advances in High Energy Physics, 2011
Finding vacua for the four-dimensional effective theories for supergravity which descend from flux compactifications and analyzing them according to their stability is one of the central problems in string phenomenology. Except for some simple toy models,
