Google Cloud Professional Data Engineer — Question 269

Your neural network model is taking days to train. You want to increase the training speed. What can you do?

Answer options

• A. Subsample your test dataset.
• B. Subsample your training dataset.
• C. Increase the number of input features to your model.
• D. Increase the number of layers in your neural network.

Correct answer: B

Explanation

Subsampling your training dataset (Option B) will lead to a faster training process as it reduces the amount of data the model has to process. Options A and D would not improve training speed, and increasing the number of input features (Option C) could actually slow down training by adding complexity.
