NCA-GENL Question 96
Select 3You are working as part of a team developing a generative AI model and are tasked with conducting initial data analysis under the guidance of a senior team member. During the analysis, you identify missing values in several key features of your dataset. What should you do next?
- A
Consult the senior team member to decide on an appropriate imputation strategy for the missing values.
- B
Remove all rows with missing values to ensure a clean dataset.
- C
Analyze the distribution of the missing data to determine its potential impact on the model.
- D
Ignore the missing values for now and proceed with training the generative AI model.
- E
Document the missing data issue and propose potential solutions for team review.
Show answer and explanation
Correct answers: A, C, E
Explanation
In generative AI workflows, addressing missing data requires careful analysis and collaboration. Consulting a senior team member (Option 1) ensures decisions are informed by expertise. Analyzing the distribution of missing data (Option 3) is critical for understanding its impact, while documenting the issue and proposing solutions (Option 5) supports team communication and problem-solving. These steps collectively ensure a robust and well-prepared dataset for training.
- A. Correct.
Consulting the senior team member is essential as they can guide you in selecting the most appropriate imputation or handling strategy, ensuring it aligns with the project's goals.
- B. Incorrect.
Removing all rows with missing values is not always recommended as it could lead to significant data loss, especially in generative AI tasks requiring diverse and large datasets.
- C. Correct.
Analyzing the distribution of missing data is a critical step in understanding the extent and nature of the issue, which helps in determining the best handling method.
- D. Incorrect.
Ignoring missing values and proceeding with training would likely lead to suboptimal results, as the model might fail to generalize well or produce biased outputs.
- E. Correct.
Documenting the issue and proposing solutions is a responsible approach that ensures transparency and fosters collaboration within the team.
