Web2 days ago · Linear Regression is a machine learning algorithm based on supervised learning. It performs a regression task. Regression models a target prediction value based on independent variables. It is mostly used … WebWe build a model on the training data and test it on the test data. Sklearn provides a function train_test_split to do this task. It returns two arrays of data. Here we ask for 20% of the data in the test set. train, test = train_test_split (iris, test_size=0.2, random_state=142) print (train.shape) print (test.shape)
