Questions & Step-by-Step Solutions

Which of the following best describes 'model drift'?
  • Step 1: Understand that a model is a tool used to make predictions based on data.
  • Step 2: Realize that the data the model was trained on can change over time.
  • Step 3: Know that when the new data is different from the data used to train the model, the model may not perform as well.
  • Step 4: This decrease in performance or accuracy of the model over time is called 'model drift'.
  • Step 5: Model drift happens because the patterns in the data have changed, making the model less effective.
