Topic 1 Question 20
You are training an LSTM-based model on AI Platform to summarize text using the following job submission script: gcloud ai-platform jobs submit training $JOB_NAME
--package-path $TRAINER_PACKAGE_PATH
--module-name $MAIN_TRAINER_MODULE
--job-dir $JOB_DIR
--region $REGION
--scale-tier basic
--
--epochs 20
--batch_size=32
--learning_rate=0.001
You want to ensure that training time is minimized without significantly compromising the accuracy of your model. What should you do?
- Modify the 'epochs' parameter.
- Modify the 'scale-tier' parameter.
- Modify the 'batch size' parameter.
- Modify the 'learning rate' parameter.

- B. Changing the scale tier does not impact performance–only speeds up training time. Epochs, Batch size, and learning rate all are hyperparameters that might impact model accuracy.

- Go with B, all the other options could affect the accuracy.

- Should be B. Question didn't say anything about cost, so while B would increase cost with more computation time, it would save real-world time.
