Explanation
During the model prototyping phase using Jupyter notebooks, the focus should be on rapid experimentation, interpretability, and reproducibility. Actions such as working with smaller datasets, utilizing notebook features for insights, and tracking experiments are critical to an efficient workflow. Premature deployment or optimization can hinder progress and lead to suboptimal outcomes.
- A. Correct.
Using smaller, representative subsets of the dataset during prototyping helps reduce computational complexity and speeds up iteration, which is essential during the experimentation phase.
- B. Incorrect.
Deploying a model immediately after initial prototyping is not recommended because the model needs thorough validation, testing, and optimization before deployment.
- C. Correct.
Leveraging Jupyter notebook features like visualizations and inline documentation helps in understanding the model's performance and communicating insights effectively.
- D. Incorrect.
Hyperparameter optimization is typically performed after ensuring that the model performs reasonably well on validation data. Premature optimization may waste resources and time during the prototyping phase.
- E. Correct.
Tracking key experiments and results is crucial to ensure reproducibility and to understand which configurations or approaches work best, even during prototyping.
