You have developed and deployed an end-to-end machine learning pipeline that includes several stages, with hyperparameter tuning being one of the critical steps. Utilizing Google AI Platform, you perform hyperparameter tuning to optimize your model's performance before proceeding to the training phase. Recently, you observed that the hyperparameter tuning process is taking significantly longer than anticipated, causing delays in your overall workflow and downstream processes. To minimize these delays, you aim to accelerate the hyperparameter tuning job without significantly compromising its effectiveness. Which actions should you take? (Choose two.)
