An svm classification algorithm with error correction ability applied to face recognition. In: Proceedings of the Third International Conference on Advances in Neural Networks, Volume Part I, ISNN'06. Springer-Verlag, Berlin, Heidelberg, pp. 1057-1062....
Support Vector Machine (SVM) algorithm in python & machine learning is a simple yet powerful Supervised ML algorithm that can be used for both regression & classification models.
CVSVMModelis aClassificationPartitionedModelclassifier. It contains the propertyTrained, which is a 1-by-1 cell array holding aCompactClassificationSVMclassifier that the software trained using the training set. Determine how well the algorithm generalizes by estimating the test sample hinge loss. ...
Sigmoid kernel.This kernel function is similar to the RBF kernel but has a different shape that can be useful for some classification problems. The choice of kernel function for an SVM algorithm is a tradeoff between accuracy and complexity. The more powerful kernel functions, such as the RBF ...
compressed sensing theory. Furthermore, multi-classification SVM is used to establish a mapping relationship between the feature vector of the defect signal and the actual defect type of the pipeline, and Genetic Algorithm-Particle Swarm Optimization is used to guide the selection of SVM parameters....

SVMModel is a trained ClassificationSVM classifier, whose properties include the support vectors, linear predictor coefficients, and bias term. sv = SVMModel.SupportVectors; % Support vectors beta = SVMModel.Beta; % Linear predictor coefficients b = SVMModel.Bias; % Bias term Plot a scatter diag...
We also used linear PCA feature extraction and the SVM classification algorithm compared with the method of this paper. The remainder of the paper is organized as follows: in Section 1, we introduce the merit of UWB radar in the field of target recognition and elaborated the main research ...
