Google Professional Machine Learning Engineer Exam - Topic 3 Question 22 Discussion

You built and manage a production system that is responsible for predicting sales numbers. Model accuracy is crucial, because the production model is required to keep up with market changes. Since being deployed to production, the model hasn't changed; however the accuracy of the model has steadily deteriorated. What issue is most likely causing the steady decline in model accuracy?
D) Incorrect data split ratio during model training, evaluation, validation, and test
A) Poor data quality
B) Lack of model retraining
C) Too few layers in the model for capturing information

Incorrect data split ratio might be a problem too.

Wait, how can the model just get worse without changes?

Too few layers could be a factor, but not the main issue.

I think it's poor data quality, honestly.

I think the model might just be too simple. Option C sounds plausible, but I’m not entirely convinced.

I’m not so sure about that. Could it also be poor data quality? I feel like we went over that in class, but I can't recall the specifics.

I remember we discussed how models can degrade over time if they aren't retrained. I think option B might be the right answer.

I remember a practice question about data splits affecting model performance. Option D could be relevant, but it seems less likely than retraining issues.

Okay, let's think this through. The question is asking about the Designated Router (DR) on the OSPFv3 network. Since the command output on R3 shows that R1 and R2 are the DRs, the answer must be TRUE.

Hmm, I remember learning about RIP in class, but I'm a bit fuzzy on the details. I'll try to recall the key information and make an educated guess.

Hmm, this seems straightforward. I'll need to think through the key elements of a mobile page.
