Question 200

After a planned change, the release team needs evidence of the expected outcome. The change is: Use a managed image-labeling API such as Rekognition for supported generic categories. This relates to a situation where a content team needs general-purpose object and scene labels for uploaded catalog pictures but does not have enough examples to train a custom computer-vision model. What outcome should the team look for if that change succeeds?

  1. The application obtains image tags without maintaining custom training infrastructure.
  2. Audio is converted into reviewable text that can feed downstream NLP.
  3. The system provides risk probabilities that can be thresholded for downstream policy.
  4. Similar shoppers can be grouped into exploratory segments without a labeled target.

Explanation

Correct Answer

A:

This is the expected observable result: The application obtains image tags without maintaining custom training infrastructure. It follows when engineers use a managed image-labeling API such as Rekognition for supported generic categories. The team must still consider the limitation: Generic pretrained labels may not recognize specialized products or fulfill strict domain accuracy.

Incorrect Answers

B:

That result concerns a call center wants searchable text transcripts of recorded telephone calls, including the words spoken, without manually annotating hours of audio. It would not demonstrate that the application obtains image tags without maintaining custom training infrastructure.

C:

That result concerns a lender needs a probability that an applicant will default, not a continuous estimated loan amount, and requires threshold-based risk decisions. It would not demonstrate that the application obtains image tags without maintaining custom training infrastructure.

D:

That result concerns a retail company has customer browsing features but no ground-truth group labels and wants exploratory behavior segments for later campaigns. It would not demonstrate that the application obtains image tags without maintaining custom training infrastructure.

Question 201

An implementation review needs the operational result of this step: Prefer an interpretable linear classifier with documented preprocessing and feature contribution analysis. This relates to a situation where a compliance-sensitive classifier needs understandable positive and negative influences of a few engineered features, and a deep opaque model is unnecessary. What outcome should the team look for if that change succeeds?

  1. The application obtains image tags without maintaining custom training infrastructure.
  2. The system provides risk probabilities that can be thresholded for downstream policy.
  3. The classifier can learn nonlinear interactions without a manually engineered deep network.
