Question
Regression model accuracy is not measured bymean square errormean absolute errorroot mean square erroraccuracy score
Solution
The accuracy of a regression model is not measured by the "accuracy score". The accuracy score is typically used for classification models, not regression models. For regression models, we typically use other metrics such as Mean Squared Error (MSE), Mean Absolute Error (MAE), or Root Mean Squared Error (RMSE). These metrics provide a measure of how well the model's predictions match the actual values.
