On the Convergence Rate of Quasi-Newton Methods on Strongly Convex Functions with Lipschitz Gradient

Mathematics, 2023
The main results of the study of the convergence rate of quasi-Newton minimization methods were obtained under the assumption that the method operates in the region of the extremum of the function, where there is a stable quadratic representation of the ...

Subgroup Discovery in Machine Learning Problems with Formal Concepts Analysis and Test Theory Algorithms

Algorithms, 2023
A number of real-world problems of automatic grouping of objects or clustering require a reasonable solution and the possibility of interpreting the result. More specific is the problem of identifying homogeneous subgroups of objects.

Mixnet optimization methods

Proceedings on Privacy Enhancing Technologies, 2022
We propose a method to optimally select mix network parameters for a given deployment context and adversarial model. Our method considers both worstcase and average-case anonymity and selects configurations that meet worst-case constraints while maximizing average anonymity.

Properties of the Quadratic Transformation of Dual Variables

Algorithms, 2023
We investigate a solution of a convex programming problem with a strongly convex objective function based on the dual approach. A dual optimization problem has constraints on the positivity of variables.

The optimal triangulation method is not really optimal

IET Image Processing, 2023
Abstract Triangulation refers to the problem of finding a 3D point from its 2D projections on multiple images taken at different camera poses. For solving this problem, it is a common practice to use the so‐called optimal triangulation method.
