From sklearn import svm tree
Websvm import SVC) for fitting a model. SVC, or Support Vector Classifier, is a supervised machine learning algorithm typically used for classification tasks. SVC works by mapping data points to a high-dimensional space and then finding the optimal hyperplane that divides the data into two classes. WebJan 15, 2024 · Summary. The Support-vector machine (SVM) algorithm is one of the Supervised Machine Learning algorithms. Supervised learning is a type of Machine Learning where the model is trained on historical data …
