Question #: 29
Topic #: 7

[All Professional Machine Learning Engineer Questions]

You were asked to investigate failures of a production line component based on sensor readings. After receiving the dataset, you discover that less than 1% of the readings are positive examples representing failure incidents. You have tried to train several classification models, but none of them converge. How should you resolve the class imbalance problem?

AUse the class distribution to generate 10% positive examples

BUse a convolutional neural network with max pooling and softmax activation

CDownsample the data with upweighting to create a sample with 10% positive examples

DRemove negative examples until the numbers of positive and negative examples are equal

Convolutional networks might not be the best fit here.

Wait, removing negatives? That seems extreme!

Generating more positive examples sounds like a solid plan.

I think downsampling is risky, might lose important data.

Using a CNN sounds interesting, but I don't recall it being a common solution for class imbalance issues.

I think downsampling could work, but I'm uncertain about how effective it would be in this case.

I remember reading about class imbalance, but I'm not sure if generating more positive examples is the best approach.

I practiced a similar question where we had to balance classes, and I think removing negatives might lead to losing important data.

I'm feeling pretty confident about this one. The drone control should run in the edge cloud for low latency, and the video app can run in the central cloud since it's less sensitive to latency.

This looks like a tricky one. I'll need to carefully analyze the structure and element names to determine the correct Send JSON Path.

Hmm, I'm not confident. Is this about how companies might accidentally create environments that encourage unethical behavior?

This question seems a bit tricky. I'll need to carefully read through the options to understand the nuances of Alibaba Cloud's intranet communication policies.

The command looks straightforward, but I'm not 100% sure. I'll have to double-check the Docker documentation to be certain.
