A new conjugate gradient method for acceleration of gradient descent algorithms

open access: yesMoroccan Journal of Pure and Applied Analysis, 2021
An accelerated of the steepest descent method for solving unconstrained optimization problems is presented. which propose a fundamentally different conjugate gradient method, in which the well-known parameter βk is computed by an new formula.

Gradient-only line searches: An Alternative to Probabilistic Line Searches

open access: yesCoRR, 2019
Step sizes in neural network training are largely determined using predetermined rules such as fixed learning rates and learning rate schedules. These require user input or expensive global optimization strategies to determine their functional form and associated hyperparameters. Line searches are capable of adaptively resolving learning rate schedules.

Revisiting the Problem of Searching on a Line [PDF]

open access: yes, 2013
We revisit the problem of searching for a target at an unknown location on a line when given upper and lower bounds on the distance D that separates the initial position of the searcher from the target. Prior to this work, only asymptotic bounds were known for the optimal competitive ratio achievable by any search strategy in the worst case. We present

Competitive Searching for a Line on a Line Arrangement.

open access: yes, 2018
We discuss the problem of searching for an unknown line on a known or unknown line arrangement by a searcher S, and show that a search strategy exists that finds the line competitively, that is, with detour factor at most a constant when compared to the situation where S has all knowledge. In the case where S knows all lines but not which one is sought,
