Google Professional-Machine-Learning-Engineer Question Answer
You have trained a DNN regressor with TensorFlow to predict housing prices using a set of predictive features. Your default precision is tf.float64, and you use a standard TensorFlow estimator;
estimator = tf.estimator.DNNRegressor(
feature_columns=[YOUR_LIST_OF_FEATURES],
hidden_units-[1024, 512, 256],
dropout=None)
Your model performs well, but Just before deploying it to production, you discover that your current serving latency is 10ms @ 90 percentile and you currently serve on CPUs. Your production requirements expect a model latency of 8ms @ 90 percentile. You are willing to accept a small decrease in performance in order to reach the latency requirement Therefore your plan is to improve latency while evaluating how much the model ' s prediction decreases. What should you first try to quickly lower the serving latency?
