GridSearchCV implements a “fit” and a “score” method. It also … NettetIf computational expense is an issue, then rather than use grid search, ... If k-nearest neighbor (kNN) or linear regression works better, then you shouldn't use a more expensive (computationally) approach like SVM. SVM can be easily overused, so make sure you evaluate linear regression, kNN, linear discriminant analysis, ...

Nettet13. jan. 2024 · $\begingroup$ It's not quite as bad as that; a model that was actually trained on all of x_train and then scored on x_train would be very bad. The 0.909 number is the average of cross-validation scores, so each individual model was scored on a subset of x_train that it was not trained on. However, you did use x_train for the GridSearch, … NettetLinear Regression. Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data.
