The CUSTOM tier for Cloud Machine Learning Engine allows you to specify the number of which types of cluster nodes?
Options:
A.
Workers
B.
Masters, workers, and parameter servers
C.
Workers and parameter servers
D.
Parameter servers
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 of the following statements about the Wide & Deep Learning model are true? (Select 2 answers.)
Options:
A.
The wide model is used for memorization, while the deep model is used for generalization.
B.
A good use for the wide and deep model is a recommender system.
C.
The wide model is used for generalization, while the deep model is used for memorization.
D.
A good use for the wide and deep model is a small-scale linear regression problem.
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.
