Recognizing concept drift | AWS Certified AI Practitioner (AIF-C01) original practice question

1.2Standard

Input distribution is stable but the relationship to outcomes changes.

Investigate degradation.

Choose two checks.

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

Detailed explanation

CorrectCompare input distribution, prediction distribution, label relationships, and errors by period

Relationship changes can be isolated.

CorrectReview business, label, user, and model-version changes over time

Causes can be traced.

IncorrectStable inputs prove the model relationship is unchanged

Concept drift can remain.

IncorrectAssume low volume is the only cause and skip label review

The cause may be wrong.

An example you can run in a temporary verification environment.
