NCA-GENL Question 138
Select 2You are tasked with analyzing the performance of a generative AI model trained to generate customer support responses. After evaluating the model, you need to present the results to stakeholders. Which of the following visualizations would be most effective to convey the success rate of the model across different support categories (e.g., Billing, Technical Support, Account Issues)?
- A
A bar chart showing the percentage success rate for each support category.
- B
A pie chart displaying the proportion of successful responses across all categories.
- C
A line graph showing the trend of the model's success rate over time.
- D
A scatter plot comparing the model's success rates with response times.
- E
A heatmap visualizing success rates for different categories and time periods.
Show answer and explanation
Correct answers: A, E
Explanation
To convey the success rate of the generative AI model across different support categories, visualizations like bar charts and heatmaps are most effective. Bar charts provide a clear and straightforward comparison of success rates between categories, while heatmaps can offer additional insights by incorporating time periods or other dimensions. These visualizations align with the goal of presenting detailed, category-specific performance metrics to stakeholders.
- A. Correct.
A bar chart is highly effective for showing the success rate of the model across discrete categories, making it easy for stakeholders to compare performance between categories like Billing and Technical Support.
- B. Incorrect.
A pie chart shows proportions rather than detailed comparisons across categories, which can make it less suitable for conveying success rates for specific categories.
- C. Incorrect.
A line graph is best used for showing trends over time, which isn't the primary goal of this task since the focus is on category-specific success rates rather than temporal changes.
- D. Incorrect.
A scatter plot is used to analyze relationships between two variables, such as success rate and response time, which isn't the main focus of this scenario.
- E. Correct.
A heatmap can effectively represent success rates across both categories and time periods, giving stakeholders a comprehensive view of the model's performance.
