Structured development of problem solving methods [PDF]

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2001
This paper, published in one of the top journals in Computer Science, describes the UPML framework for modelling knowledge-based applications, which can be seen as the culmination of over twenty years of research in this area. UPML has shaped the field, providing the intellectual and formal basis for the WSMO framework, which is the cornerstone of ...

A note on phase-lag computations for multiderivative methods for second order periodic initial value problems [PDF]

open access: yes, 1985
Phase—lag computations are carried out for a family of two-step multiderivative methods for solving second order initial value problems of the form y" = f(t,y), y(t0) = y0, y'(t0) = z0.

Conforming finite element methods for the clamped plate problem [PDF]

open access: yes, 1975
Finite element methods for solving biharmonic boundary value problems are considered. The particular problem discussed is that of a clamped thin plate. This problem is reformulated in a weak, form in the Sobolev space Techniques for setting up conforming

Inertial Extragradient Methods for Solving Split Equilibrium Problems

open access: yesMathematics, 2021
This paper presents two inertial extragradient algorithms for finding a solution of split pseudomonotone equilibrium problems in the setting of real Hilbert spaces. The weak and strong convergence theorems of the introduced algorithms are presented under

ENSEMBLE METHODS FOR SOLVING PROBLEMS OF MEDICAL DIAGNOSIS

open access: yesИзвестия Томского политехнического университета: Промышленная кибернетика, 2023
The authors proposed the consolidating method for analyzing series of observations based on a fitted model of a mixture of catalysts of the main components, which makes it possible to study any number of markers. Contrasting the longitudinal approach, it

Two Novel SMOTE Methods for Solving Imbalanced Classification Problems

open access: yesIEEE Access, 2023
The imbalanced classification problem has always been one of the important challenges in neural network and machine learning. As an effective method to deal with imbalanced classification problems, the synthetic minority oversampling technique (SMOTE ...

Some Iterative Methods for Solving Equilibrium Problems and Optimization Problems

open access: yesJournal of Inequalities and Applications, 2010
We introduce a new iterative scheme for finding a common element of the set of solutions of the equilibrium problems, the set of solutions of variational inequality for a relaxed cocoercive mapping, and the set of fixed points of a nonexpansive mapping.
