Answer-first summary for fast verification
Answer: Enable the early stopping parameter to halt trials that do not show improvement, saving time and resources., Reduce the maximum number of trials in subsequent training phases to limit the exploration time.
Enabling early stopping (Option C) is a highly effective strategy as it stops trials that are not showing improvement, thereby saving time without significantly affecting the tuning's effectiveness. Reducing the maximum number of trials (Option E) is another practical approach when time is of the essence, though it may slightly limit the exploration of the hyperparameter space. These strategies provide a balance between speed and efficiency, avoiding less effective methods such as altering the search algorithm or expanding the range of values without clear justification.

In your role as a Machine Learning Engineer at a fast-growing tech company, you're responsible for optimizing the end-to-end ML pipeline. The pipeline currently includes hyperparameter tuning on AI Platform, which is taking longer than anticipated, causing delays in downstream processes. The team is under pressure to deliver results quickly without compromising the quality of the model. Given the constraints of time and the need to maintain model effectiveness, which two strategies would you implement to speed up the hyperparameter tuning job? (Choose two.)
A
Increase the number of parallel trials to explore more hyperparameter combinations simultaneously.
B
Expand the range of floating-point values for hyperparameters to ensure a broader search space.
C
Enable the early stopping parameter to halt trials that do not show improvement, saving time and resources.
D
Switch the search algorithm from random search to Bayesian search for more efficient exploration of the hyperparameter space.
E
Reduce the maximum number of trials in subsequent training phases to limit the exploration time.
