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.
In other words, the software attempts to remove 100p% of the observations when the optimization algorithm converges. The removed observations correspond to gradients that are large in magnitude. If your predictor data contains categorical variables, then the software generally uses full dummy encoding ...
Mdl= fitcsvm(Tbl,Y)returns an SVM classifier trained using the predictor variables in the tableTbland the class labels in vectorY. Mdl= fitcsvm(X,Y)returns an SVM classifier trained using the predictors in the matrixXand the class labels in vectorYfor one-class or two-class classification. ...
This new approach will make the combination of SVM algorithm with Self-Organized Ant Colony Network (CSOACN) algorithm to take advantages of both while avoiding their limitations. The basic task of this approach is to classify network packet as normal or abnormal while minimizing misclassifi...
We propose an improved version of the SMO algorithm for training classification and regression SVMs, based on a Conjugate Descent procedure. This new approach only involves a modest increase on the computational cost of each iteration but, in turn, usually results in a substantial decrease in the...
Random Forest is a popular flexible machine learning algorithm, which is established with a number of decision trees [18]. Each decision tree was created at the time of training and grown using a randomization form and outputting the class of the individual trees [41]. 2.5.3. Naïve Bayes...

For this problem, the extreme support vector machine with a linear kernel, which has the same form as the linear PSVM [7], is Parallelization of ESVM based on MapReduce To make ESVM algorithm has a good scalability, and run faster when the input data set is very large, we propose a ...
Further details on these two steps can be seen in Algorithm 1. In addition, we introduce SVM into our algorithm, which is a classical supervised learning algorithm mainly used for classification and regression problems. Its goal is to find a hyperplane ω⋅x+b=0, where ω is the weight ...
