Why is using smaller datasets sometimes a good cost optimization strategy?
Smaller datasets reduce the time and computing power needed to train models, which lowers costs. But it should still keep enough data to learn well.

Which of the following is a direct way to reduce training costs?
✗ Incorrect
Smaller batch sizes reduce memory use and can speed up training, lowering costs.
What is a risk when using cloud spot instances for training?
✗ Incorrect
Spot instances can be stopped anytime, so jobs must handle interruptions.
Which technique reduces model size to save cost?
✗ Incorrect
Model pruning removes unnecessary parts to make the model smaller and cheaper to run.
Why is early stopping useful for cost optimization?
✗ Incorrect
Early stopping saves resources by ending training once the model stops improving.
Automated hyperparameter tuning helps cost optimization by:
✗ Incorrect
Automated tuning quickly finds good settings, reducing wasted time and cost.
