Quiz covering Hyperparameter Tuning

What you'll be asked

  1. What is the primary purpose of defining a 'primary metric' when running hyperparameter tuning experiments?
  2. If you are training a binary classification model on a highly imbalanced dataset where the positive class is rare, which primary metric would be most appropriate to track?
  3. When configuring an experiment to minimize prediction error in a regression task, which metric should you set as the primary objective?
  4. A data scientist is tuning a model and sets the primary metric to 'Accuracy' with a goal of 'Maximize'. What happens if the hyperparameter tuning service finds a configuration that results in an accuracy of 0.95 and another with 0.92?
  5. You are performing hyperparameter tuning using a Bayesian optimization strategy. If you change your primary metric from 'Precision' to 'F1-Score' mid-experiment, what is the most significant consequence?
