Fit_transform sklearn example

WebLet us take an example for scaling values in a dataset: Here the fit method, when applied to the training dataset, learns the model parameters (for example, mean and standard deviation). We then need to apply the transform method on the training dataset to get the transformed (scaled) training dataset. 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.
