this topic covers the fundamentals of Support Vector Machines (SVM), a powerful supervised learning algorithm widely used for classification tasks. We'll explore both linear and non-linear SVMs, learn about their underlying concepts, and see practical Python code examples. Let's dive in! 🚀 ...

We can execute the following code in order to train the model: svc.fit(X_train, y_train) Just like that, the model is trained. So far, we have understood the data, divided it, created a simple SVM model, and fitted the model to the train data. ...
