In other words, MAE is an arithmetic average of absolute errors between two sets of observation. Suppose in your Linear Regression task, you calculate predicted “y_pred” by fitting your dataset in a Linear Regression model.

Nettet5. jan. 2024 · Linear regression is a simple and common type of predictive analysis. Linear regression attempts to model the relationship between two (or more) variables by fitting a straight line to the data. Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables). NettetNext, 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.
