WebAug 16, 2024 · In a nutshell: fitting is equal to training. Then, after it is trained, the model can be used to make predictions, usually with a .predict () method call. To elaborate: Fitting your model to (i.e. using the .fit () method on) the training data is essentially the training part of the modeling process. WebFitting the SVM classifier to the training set: Now the training set will be fitted to the SVM classifier. To create the SVM classifier, we will import SVC class from Sklearn.svm library. Below is the code for it: In the above code, we have used kernel='linear', as here we are creating SVM for linearly separable data. However, we can change it ... A better fitting of the training data set as opposed to the test data set usually points to over-fitting. A test set is therefore a set of examples used only to assess the performance (i.e. generalization) of a fully specified classifier. To do this, the final model is used to predict classifications of examples in the test set. … See more In machine learning, a common task is the study and construction of algorithms that can learn from and make predictions on data.
