Question: Which evaluation metric is most appropriate for regression tasks?

Options:

Correct Answer: Mean Absolute Error (MAE)

Solution:

Mean Absolute Error (MAE) is commonly used for evaluating regression tasks as it measures the average magnitude of errors.

Which evaluation metric is most appropriate for regression tasks?

Step 1: Understand what regression tasks are. Regression tasks involve predicting a continuous value, like predicting house prices or temperatures.
Step 2: Learn about evaluation metrics. Evaluation metrics help us measure how well our predictions match the actual values.
Step 3: Identify common evaluation metrics for regression. Some common metrics include Mean Absolute Error (MAE), Mean Squared Error (MSE), and R-squared.
Step 4: Focus on Mean Absolute Error (MAE). MAE calculates the average of the absolute differences between predicted values and actual values.
Step 5: Understand why MAE is useful. MAE gives a clear idea of how far off our predictions are, without squaring the errors, which can exaggerate larger errors.
