[All Professional Machine Learning Engineer Questions]

Your team is building an application for a global bank that will be used by millions of customers. You built a forecasting model that predicts customers1 account balances 3 days in the future. Your team will use the results in a new feature that will notify users when their account balance is likely to drop below $25. How should you serve your predictions?

a user's account balance will drop below the $25 threshold

C1. Build a notification system on Firebase
2. Register each user with a user ID on the Firebase Cloud Messaging server, which sends a notification when the average of all account balance predictions drops below the $25 threshold

D1 Build a notification system on Firebase
2. Register each user with a user ID on the Firebase Cloud Messaging server, which sends a notification when your model predicts that a user's account balance will drop below the $25 threshold

I wonder if the bank's IT department has a dedicated 'Notification Fatigue Response Team' to handle all the complaints from irritated customers.

I'm not sure, but I hope the bank's customers don't get so many notifications that they start using their accounts to play the lottery instead.

C) Build a notification system on Firebase. Register each user with a user ID on the Firebase Cloud Messaging server, which sends a notification when the average of all account balance predictions drops below the $25 threshold.

Option C is an interesting approach, but I'm not sure about the idea of using the average of all account balance predictions to trigger notifications. Shouldn't we focus on individual users' accounts?

Option B looks good, but I'm not sure if the App Engine standard environment is the best choice for a global banking application. It might be overkill for this use case.

I'm leaning towards Option D. Using Firebase Cloud Messaging to send targeted notifications to each user based on their individual account balance predictions seems like a robust solution.

Option A seems like the most straightforward approach. Using a Pub/Sub topic for each user and a Cloud Function to handle the notification logic seems efficient and scalable.

That's a good point, but I still think option A is more efficient for notifying users in real-time.

I disagree, I believe option C is better as it sends a notification based on the average of all account balance predictions, providing a more comprehensive approach.

I think option A is the best choice because it directly sends a notification when the account balance is predicted to drop below $25.
