NCA-GENM Question 137

Single answer

A team is developing a multimodal generative AI model that processes both text and image inputs. During training, they notice inconsistent performance metrics across different experiment runs. Which monitoring practice would BEST help the team identify the root cause of the inconsistencies?

  1. A

    Track and log data preprocessing steps for all input modalities.

  2. B

    Increase the frequency of model checkpoint saving during training.

  3. C

    Focus solely on GPU utilization metrics during the experiments.

  4. D

    Run experiments without monitoring to prioritize faster iterations.

Show answer and explanation

Correct answer: A

Explanation

In multimodal generative AI models, data preprocessing for each input modality (e.g., text and images) must be consistent across experiments to ensure reliable performance metrics. Tracking these steps allows the team to identify and fix any discrepancies early, leading to more robust and stable training outcomes.

  • A. Correct.

    Tracking and logging data preprocessing steps ensures consistency across experiments and helps identify variances in input data handling, which can significantly impact model performance.

  • B. Incorrect.

    Saving model checkpoints more frequently may help in recovery but does not directly address inconsistencies in performance metrics caused by preprocessing or data handling issues.

  • C. Incorrect.

    Monitoring GPU utilization is helpful for hardware performance but does not aid in diagnosing inconsistencies related to data or experiments.

  • D. Incorrect.

    Skipping monitoring for faster iterations sacrifices essential insights needed to debug and identify the root cause of performance variations.
