Research on the prediction of blasting fragmentation in open-pit coal mines based on KPCA-BAS-BP
Published 2024-10-01“…The kernel principal component analysis (KPCA) is adopted to reduce the dimensionality of the input variables. The beetle antennae search algorithm (BAS) is selected to optimize the parameters of the initial weights and thresholds of the back propagation (BP) neural network. …”

Fault Diagnosis of Vehicle Gearbox based on Support Vector Machine Optimized by Improved Beetle Antennae Search
Published 2022-05-01“…Aiming at the fact that the performance of support vector machine (SVM) in vehicle gearbox fault diagnosis is greatly affected by parameters,a new method of vehicle gearbox fault diagnosis based on improved SVM is proposed based on the research of beetle antennae search (BAS). Compared with BAS,IBAS modified the step size formula and added Gaussian variation behavior,so that the search ability of the algorithm in the early and late period is balanced and has the ability to jump out of the local optimal,and better SVM parameters could be obtained. …”

High Precision and Fast Inversion of Array Lateral Logging Based on BAS-LM Algorithm
Published 2024-12-01“…To solve the problem that Levenberg-Marquarat (LM) algorithm used in geophysical inversion is highly dependent on the initial value and easily trapped in a local minimum, a strategy for optimizing the initial value selection of the basic LM algorithm using Beetle Antennae Search (BAS) algorithm is proposed to enhance the global optimization ability of the LM algorithm. …”
