Convergence Criteria of a Three-Step Scheme under the Generalized Lipschitz Condition in Banach Spaces

  • Akanksha Saxena,
  • Jai Prakash Jaiswal,
  • Kamal Raj Pardasani and
  • Ioannis K. Argyros

24 October 2022

In the given study, we investigate the three-step NTS’s ball convergence for solving nonlinear operator equations with a convergence order of five in a Banach setting. A nonlinear operator’s first-order derivative is assumed to meet the g...

Local Convergence of a Family of Weighted-Newton Methods

  • Ramandeep Behl,
  • Ioannis K. Argyros,
  • J.A. Tenreiro Machado and
  • Ali Saleh Alshomrani

17 January 2019

This article considers the fourth-order family of weighted-Newton methods. It provides the range of initial guesses that ensure the convergence. The analysis is given for Banach space-valued mappings, and the hypotheses involve the derivative of orde...

Extending the Local Convergence of a Seventh Convergence Order Method without Derivatives

  • Ioannis K. Argyros,
  • Debasis Sharma,
  • Christopher I. Argyros and
  • Sanjaya Kumar Parhi

12 April 2022

For the purpose of obtaining solutions to Banach-space-valued nonlinear models, we offer a new extended analysis of the local convergence result for a seventh-order iterative approach without derivatives. Existing studies have used assumptions up to...

Exploring Flatter Loss Landscape Surface via Sharpness-Aware Minimization with Linear Mode Connectivity

  • Hailun Liang,
  • Haowen Zheng,
  • Hao Wang,
  • Liu He,
  • Haoyi Lin and
  • Yanyan Liang

11 April 2025

The Sharpness-Aware Minimization (SAM) optimizer connects flatness and generalization, suggesting that loss basins with lower sharpness are correlated with better generalization. However, SAM requires manually tuning the open ball radius, which compl...

  • Indra Bate,
  • Muniyasamy Murugan,
  • Santhosh George,
  • Kedarnath Senapati,
  • Ioannis K. Argyros and
  • Samundra Regmi

4 September 2024

In this paper, we present a technique that improves the applicability of the result obtained by Cordero et al. in 2024 for solving nonlinear equations. Cordero et al. assumed the involved operator to be differentiable at least five times to extend a...

Boundary-Aware Hashing for Hamming Space Retrieval

  • Wenjin Hu,
  • Yukun Chen,
  • Lifang Wu,
  • Ge Shi and
  • Meng Jian

5 January 2022

Hamming space retrieval is a hot area of research in deep hashing because it is effective for large-scale image retrieval. Existing hashing algorithms have not fully used the absolute boundary to discriminate the data inside and outside the Hamming b...

Gradient Method with Step Adaptation

  • Vladimir Krutikov,
  • Elena Tovbis,
  • Svetlana Gutova,
  • Ivan Rozhnov and
  • Lev Kazakovtsev

27 December 2024

The paper solves the problem of constructing step adjustment algorithms for a gradient method based on the principle of the steepest descent. The expansion of the step adjustment principle, its formalization and parameterization led the researchers t...
