Google Professional Machine Learning Engineer Exam - Topic 9 Question 10 Discussion

Your team trained and tested a DNN regression model with good results. Six months after deployment, the model is performing poorly due to a change in the distribution of the input data. How should you address the input differences in production?
C) Retrain the model, and select an L2 regularization parameter with a hyperparameter tuning service
A) Create alerts to monitor for skew, and retrain the model.
B) Perform feature selection on the model, and retrain the model with fewer features
D) Perform feature selection on the model, and retrain the model on a monthly basis with fewer features

L2 regularization could help, but not sure if it’s the main issue here.

Wait, can a model really just stop working like that?

Monthly retraining sounds excessive, but might be necessary.

I think feature selection is overrated; just retrain with all features.

Definitely need to monitor for skew and retrain the model.

I think option D could be useful since it combines feature selection and regular retraining, but I'm not confident about the frequency.

I feel like we practiced a similar question where feature selection was mentioned, but I can't recall if it was the best approach here.

I remember we discussed the importance of monitoring for data drift, so option A seems like a good choice.

I'm not entirely sure, but I think retraining the model regularly could help. Maybe option C is worth considering?

This looks like a straightforward integration design using Azure Functions and Service Bus. I think I can handle this.

Okay, I've got this. SAML is the XML-based standard for identity and access management, used to securely exchange authentication and authorization data. I'm feeling good about selecting that as the answer.

Hmm, this looks like a tricky one. I'll need to carefully read through the question and the provided code to make sure I understand the requirements before attempting to solve it.
