Question 71

The CUSTOM tier for Cloud Machine Learning Engine allows you to specify the number of which types of cluster nodes?

Workers
Workers
Masters, workers, and parameter servers
Masters, workers, and parameter servers
Workers and parameter servers
Workers and parameter servers
Parameter servers
Parameter servers
Suggested answer: C
Explanation:

The CUSTOM tier is not a set tier, but rather enables you to use your own cluster specification. When you use this tier, set values to configure your processing cluster according to these guidelines:

You must set TrainingInput.masterType to specify the type of machine to use for your master node.

You may set TrainingInput.workerCount to specify the number of workers to use.

You may set TrainingInput.parameterServerCount to specify the number of parameter servers to use.

You can specify the type of machine for the master node, but you can't specify more than one master node.

Which software libraries are supported by Cloud Machine Learning Engine?

Theano and TensorFlow
Theano and TensorFlow
Theano and Torch
Theano and Torch
TensorFlow
TensorFlow
TensorFlow and Torch
TensorFlow and Torch
Suggested answer: C
Explanation:

Cloud ML Engine mainly does two things:

Enables you to train machine learning models at scale by running TensorFlow training applications in the cloud.

Hosts those trained models for you in the cloud so that you can use them to get predictions about new data.

Question 73

Which TensorFlow function can you use to configure a categorical column if you don't know all of the possible values for that column?

categorical_column_with_vocabulary_list
categorical_column_with_vocabulary_list
categorical_column_with_hash_bucket
categorical_column_with_hash_bucket
categorical_column_with_unknown_values
categorical_column_with_unknown_values
sparse_column_with_keys
sparse_column_with_keys
Suggested answer: B
Explanation:

If you know the set of all possible feature values of a column and there are only a few of them, you can use categorical_column_with_vocabulary_list. Each key in the list will get assigned an autoincremental ID starting from 0.

What if we don't know the set of possible values in advance? Not a problem. We can use categorical_column_with_hash_bucket instead. What will happen is that each possible value in the feature column occupation will be hashed to an integer ID as we encounter them in training.

Which of the following statements about the Wide & Deep Learning model are true? (Select 2 answers.)

The wide model is used for memorization, while the deep model is used for generalization.
The wide model is used for memorization, while the deep model is used for generalization.
A good use for the wide and deep model is a recommender system.
A good use for the wide and deep model is a recommender system.
The wide model is used for generalization, while the deep model is used for memorization.
The wide model is used for generalization, while the deep model is used for memorization.
A good use for the wide and deep model is a small-scale linear regression problem.
A good use for the wide and deep model is a small-scale linear regression problem.
Suggested answer: A, B
Explanation:

Can we teach computers to learn like humans do, by combining the power of memorization and generalization? It's not an easy question to answer, but by jointly training a wide linear model (for memorization) alongside a deep neural network (for generalization), one can combine the strengths of both to bring us one step closer. At Google, we call it Wide & Deep Learning. It's useful for generic large-scale regression and classification problems with sparse inputs (categorical features with a large number of possible feature values), such as recommender systems, search, and ranking problems.
