Exam Professional Machine Learning Engineer topic 1 question 14 discussion

B. Retraining is needed as the market is changing.

the biggest issue of this website is `all correct answers` are wrong

Model is not updated to current sales trends.

B naturally

B) You require model monitoring to identify changes and at the right time retrain the model with new data to avoid model drift.

The market can be dynamic, Sales trends, customer preferences, and even competitor strategies might evolve over time but our model hasn't changed since the deployment so our model can adapt with these changes by retraining only Degradation Over Time: Without retraining to adapt to these changes, the model's predictions become less accurate as the real world diverges from the data it was trained on.

As the consistent changes in the Market data, the Model in Production should regularly retrain for better results. Option B is the right choice

Keeping the model up to date is crucial. So - B.

B because the environment is changing and the model only captures past performance

Situation : model trained long before. Q : why accuracy of the model has steadily deteriorated. A. Poor data quality : Model perfomance depens on trained model only. Quality issue should be taken care by pipeline and it do not much affect the model to cause a performance slow down over time B. Lack of model retraining : Very obvious C. Too few layers in the model for capturing information : If so model wpould not have been deployed at first stage due to low performance on unseen data D. Incorrect data split ratio during model training, evaluation, validation, and test : This is relevant only at training when model deployed at first place, We have way passed that. Not not the reason.

Went with B

B is correct. Model needs to keep up with the market changes, implying that the underlying data distribution would be changing as well. Hence retrain the model.

The questions says the model is required to keep up with market changes, hence retraining needed.

B is the correct answer

ANS: B

Data distribution changes over time and so should do the model, so B is the correct answer

Correct answer is "B"
