Since we are going to perform a classification task, we will use the support vector classifier class, which is written as SVC in the Scikit-Learn's svm library. This class takes one parameter, which is the kernel type. SVM classifiers don't scale so easily. From the docs, about the complexity of sklearn.svm.SVC. The fit time complexity is more than quadratic with the number of samples which makes it hard to scale to dataset with more than a couple of 10000 samples.
