It calculates the argmax of predicions and give it to CLASSES list: WebIn scikit-learn, an estimator for classification is a Python object that implements the methods fit (X, y) and predict (T). An example of an estimator is the class sklearn.svm.SVC, which implements support vector classification. The estimator’s constructor takes as arguments the model’s parameters. For now, we will consider the estimator as ...
