10 (1 point) You have a linear regression model and the average R2-score value on your training data is 0.5. You perform a 100th order polynomial transform on your data then use these values to train another regression model, your average R2-score is 0.99. Which comment is correct? You should always use the simplest model 100-th order polynomial will work better on unseen data The results on your training data is not the best indicator of how your model performs, you should use your test data to get a better idea correct
