[31] also used PSO for both feature extraction and feature selection and then performed binary classification using SVM. The experiments were performed on X-ray dataset 2 and the reported accuracy of this system
Classification of Ultrasonic Non-Destructive Testing (NDT) signals can be done by Machine Learning models including Support Vector Machine (SVM) and Neural Networks (NN). The main objective of this study is to classify the ultrasonic A-scan data either as flaw echoes or clutter echoes (no flaw...
Train an SVM classifier using the processed data set. Get SVMModel = fitcsvm(X,y) SVMModel = ClassificationSVM ResponseName: 'Y' CategoricalPredictors: [] ClassNames: {'versicolor' 'virginica'} ScoreTransform: 'none' NumObservations: 100 Alpha: [24x1 double] Bias: -14.4149 KernelParameters...
Linear SVM implements an algorithm that finds a hyperplane in the feature space for binary classification, by solving an SVM problem. For instance, for a given feature vector, the prediction is given by determining what side of the hyperplane the point falls into. That is the same as the sig...
The ClassificationSVM Predict block classifies observations using an SVM classification object (ClassificationSVM or CompactClassificationSVM) for one-class and two-class (binary) classification.

Classifying New Data with an SVM Classifier Classify new data using predict. The syntax for classifying new data using a trained SVM classifier (SVMModel) is: [label,score] = predict(SVMModel,newX); The resulting vector, label, represents the classification of each row in X. score is an ...
