 | linear/lr        | The Linear predictor, will try to predict a memory usage that is linear to the task input size.                                                                                         |
 | linear2/lr2      | The Linear predictor with an unequal loss function. The loss penalizes underprediction more than overprediction.                                                                        |
 | mean             | The Mean predictor predicts the mean memory seen so far. Prediction is independent of the input size.                                                                                   |
