Web29 jun. 2024 · Next, we need to create an instance of the Linear Regression Python object. We will assign this to a variable called model. Here is the code for this: model = LinearRegression () We can use scikit-learn ’s fit method to train this model on our training data. model.fit (x_train, y_train) Our model has now been trained. WebThe most common algorithm uses an iterative refinement technique. Due to its ubiquity, it is often called "the k-means algorithm"; it is also referred to as Lloyd's algorithm, particularly in the computer science community.It is sometimes also referred to as "naïve k-means", because there exist much faster alternatives.. Given an initial set of k means m 1 (1), ..., …

Passing X_train and y_test will result in a data mismatch: once you have splitted your data in training and test set (here's why you do it and some ways to do that), you will have the output/label of your X_train in your y_train, and that goes the same for your test set.
