Parametric modeling of visual search efficiency in real scenes.

open access: yesPLoS ONE, 2015
How should the efficiency of searching for real objects in real scenes be measured? Traditionally, when searching for artificial targets, e.g., letters or rectangles, among distractors, efficiency is measured by a reaction time (RT) × Set Size function ...

Neural architecture search based on dual attention mechanism for image classification

open access: yesMathematical Biosciences and Engineering, 2023
Deep learning neural networks based on the manual design for image classification tasks usually require a large amount of a priori knowledge and experience from experts; thus, research on designing neural network architectures automatically has been ...

Non-Parametric Calibration of the Inverse Kinematic Matrix of a Three-Wheeled Omnidirectional Mobile Robot Based on Genetic Algorithms

open access: yesApplied Sciences, 2023
Odometry is a computation method that provides a periodic estimation of the relative displacements performed by a mobile robot based on its inverse kinematic matrix, its previous orientation and position, and the estimation of the angular rotational ...

Parameter Identification of Motors by Cuckoo Search Using Steady-State Relations

open access: yesIEEE Access, 2021
The direct current (DC) motors are widely used; therefore, they are subject to multiple studies, different control techniques or analyses require a dynamic DC motor model.

Magnetic Field-Resilient Quantum-Limited Parametric Amplifier

open access: yesPRX Quantum, 2023
Superconducting parametric amplifiers are crucial components in microwave quantum circuits for enabling quantum-limited signal readout. The best-performing such amplifiers are often based on Josephson junctions, which however are sensitive to magnetic ...

Ray Shooting and Parametric Search [PDF]

open access: yesSIAM Journal on Computing, 1992
Summary: Efficient algorithms for the ray shooting problem are presented: Given a collection \(\Gamma\) of objects in \(\mathbb{R}^ d\), build a data structure so that, for a query ray, the first object of \(\Gamma\) hit by the ray can be quickly determined. Using the parametric search technique, this problem is reduced to the segment emptiness problem.

Zero-Delay Joint Source Channel Coding for a Bivariate Gaussian Source over the Broadcast Channel with One-Bit ADC Front Ends

open access: yesEntropy, 2021
In this work, we consider the zero-delay transmission of bivariate Gaussian sources over a Gaussian broadcast channel with one-bit analog-to-digital converter (ADC) front ends. An outer bound on the conditional distortion region is derived.

Parametric Models of Local Search Progression [PDF]

open access: yesSSRN Electronic Journal, 2008
AbstractAlgorithms that search for good solutions to optimization problems present a trace of current best objective values over time. We describe an empirical study of parametric models of this progression that are both interesting as ways to characterize the search progression compactly and useful as means of predicting search behavior.
