Performance Evaluation of Kernels in Support Vector Machine

IEEE

Recently, the Support Vector Machine (SVM) algorithm becomes very common technique that developed for pattern classification. This technique has been employed in many fields such as bioinformatics and with different attributes of datasetsfor instance numeric, nominal or mixed. One of the significant issues that user faces when implementing the SVM is choosing the appropriate kernel function with attributes of datasetto be investigated. This paper studied the behavior of SVM in regarding to the used attributes of dataset with different kernel functions. It analyzed the influence of various datasets descriptions on efficiency of (SVM)classification.SVM with these kernels have been implemented in Matlab. The investigated kernel functions are linear, polynomials, Sigmoid and Radial Based Function (RBF). The evaluation process shows that the description of dataset with the used kernel function affects the performance of SVM classifier. Generally, SVM with linear and RBF achieved 100% in classification process when Mushroom dataset is used, and 99% when Sickle Cell Disease (SCD) is used.

An Efficient Classification System for Medical Diagnosis using SVM

Classification is a data mining and machine learning task aimed at building a classifier using some training instances for predicting classes for new instances .Building effective classification systems is one of the central tasks of data mining. Support Vector Machines (SVMs) are among the most popular and successful classification algorithms The SVM approach to machine learning is known to have both theoretical and practical advantages. The accuracy of an SVM model is largely dependent on the selection of the model parameters such as C, Gamma and P. There are a number of parameters such as C, Degree and Gamma that apply to the SVM model and the selected kernel function. Kernel techniques have long been used in SVM to handle linearly inseparable problems by transforming data to a high dimensional space. Selecting the optimal values can significantly impact the accuracy of the model. This paper aims to establish an accurate SVM classification model for Medical prediction, in order to make full use of the invaluable information in clinical data, especially which is usually ignored by most of the existing methods when they aim for high prediction accuracies. This paper presents a comparison among the different SVM kernels with different parameters on the three medical data sets. The empirical results demonstrate the ability to use more generalized kernel functions and it goes to prove that the polynomial and RBF kernel's performance is consistently improved with suitable parameters like degree and gamma. Experimental results show that kernel selection greatly improves the quality of classification.

Detection of fetal distress though a support vector machine based on fetal heart rate parameters

Computers in Cardiology, 2005, 2005

This work aimed at realizing an automatic system for diagnosing fetal sufferance through advanced classification methods applied to reliable indexes extracted from fetal heart rate (FHR) recordings. We selected a set of FHR recordings from a database of 909 exams, which were supplied with the diagnosis at the delivery. The analysis was based on both classical parameters taken from the obstetrical clinical literature and some new indexes already used for HR variability in adults, like the power spectral density (PSD) and the approximate entropy (ApEn). This parameter set was then used as input of a learning machine based on the support vector machine (SVM) algorithm. We obtained a dichotomic classifier, performing the detection of suffering IUGR fetuses from healthy ones. A high percentage of correct classifications, above 84%, was reached by filtering the training set with only 65 of the starting 909 available records.

Performance evaluation of linear discriminant analysis and support vector machines to classify cesarean section

Eastern-European Journal of Enterprise Technologies

Currently the hospital is a place that is very vulnerable to the transmission of Covid-19, so giving birth in a hospital is very risky. In addition, the hospital currently only accepts cesarean deliveries, while mothers who can give birth vaginally are recommended to give birth in a midwife because the chances of being exposed to Covid-19 are much lower. In general, this study aims to examine the performance of the LDA-SVM method in predicting whether a prospective mother needs to undergo a C-section or simply give birth normally. The aims of this study are: 1) to determine the best parameters for building the detection model; 2) to determine the best accuracy from the model; 3) to compare the accuracies with the other methods. The data used in this study is the dataset of caesarian section. This data consists of the results of 80 pregnant women following C-section with the most important characteristics of labor problems in the clinical field. Based on the results of the experiment...

An empirical assessment of different kernel functions on the performance of support vector machines

Bulletin of Electrical Engineering and Informatics, 2021

Artificial intelligence (AI) and machine learning (ML) have influenced every part of our day-today activities in this era of technological advancement, making a living more comfortable on the earth. Among the several AI and ML algorithms, the support vector machine (SVM) has become one of the most generally used algorithms for data mining, prediction and other (AI and ML) activities in several domains. The SVM's performance is significantly centred on the kernel function (KF); nonetheless, there is no universal accepted ground for selecting an optimal KF for a specific domain. In this paper, we investigate empirically different KFs on the SVM performance in various fields. We illustrated the performance of the SVM based on different KF through extensive experimental results. Our empirical results show that no single KF is always suitable for achieving high accuracy and generalisation in all domains. However, the gaussian radial basis function (RBF) kernel is often the default choice. Also, if the KF parameters of the RBF and exponential RBF are optimised, they outperform the linear and sigmoid KF based SVM method in terms of accuracy. Besides, the linear KF is more suitable for the linearly separable dataset.

Using Kernel Methods and Model Selection for Prediction of Preterm Birth

2016

We describe an application of machine learning to the problem of predicting preterm birth. We conduct a secondary analysis on a clinical trial dataset collected by the National In- stitute of Child Health and Human Development (NICHD) while focusing our attention on predicting different classes of preterm birth. We compare three approaches for deriving predictive models: a support vector machine (SVM) approach with linear and non-linear kernels, logistic regression with different model selection along with a model based on decision rules prescribed by physician experts for prediction of preterm birth. Our approach highlights the pre-processing methods applied to handle the inherent dynamics, noise and gaps in the data and describe techniques used to handle skewed class distributions. Empirical experiments demonstrate significant improvement in predicting preterm birth compared to past work.
