On the Role of Training Data for SVM-Based Microwave Brain Stroke Detection and Classification

Abstract: The aim of this work was to test microwave brain stroke detection and classification using support vector machines (SVMs). We tested how the nature and variability of training data and system parameters impact the achieved classification accuracy. Using experimentally verified numerical models, a large database of synthetic training and test data was created. The models consist of an antenna array surrounding reconfigurable geometrically and dielectrically realistic human head phantoms with virtually inserted … Show more

“…In this paper, the raw signals were set as the input data of the Learning-by-Examples (LBE) strategies. The study in [19] is a continuation of the previous research in [20]. In [19], the raw signals were proposed by using the Principal Component Analysis (PCA) algorithm to improve the accuracy of the classification.…”

“…The study in [19] is a continuation of the previous research in [20]. In [19], the raw signals were proposed by using the Principal Component Analysis (PCA) algorithm to improve the accuracy of the classification. However, the algorithms proposed in [20] only trained on the data obtained from numerical simulations.…”

“…SVMs were selected for this work for their reportedly high performance in stroke classification [24,78]. Moreover, SVMs are guaranteed to converge to the global minimum regardless of initial conditions due to their implementation of quadratic programming [79].…”

“…Support vector machine (SVM) is commonly used to solve binary classification problems and is widely used in areas such as image processing, text recognition, and medical detection (Botros, Mourad-Chehade, & Laplanche, 2022;Pokorny et al, 2023). It has recently been applied to detecting several adulterants in milk with remarkable results (Amsaraj, Ambade, & Mutturi, 2021).In this experiment, we use the support vector machine (SVM) as the second baseline model with penalty factors set to: 0:1,1:3.6 and gamma of 0.1.…”
