As the lead ML Engineer for your company, you are responsible for building ML models to digitize
scanned customer forms. You have developed a TensorFlow model that converts the scanned images
into text and stores them in Cloud Storage. You need to use your ML model on the aggregated data
collected at the end of each day with minimal manual intervention. What should you do?
Select the answer
1 correct answer
A.
Use the batch prediction functionality of Al Platform
B.
Create a serving pipeline in Compute Engine for prediction
C.
Use Cloud Functions for prediction each time a new data point is ingested
D.
Deploy the model on Al Platform and create a version of it for online inference.

You work for a global footwear retailer and need to predict when an item will be out of stock based
on historical inventory dat
a. Customer behavior is highly dynamic since footwear demand is influenced by many different
factors. You want to serve models that are trained on all available data, but track your performance
on specific subsets of data before pushing to production. What is the most streamlined and reliable
way to perform this validation?
Select the answer
1 correct answer
A.
Use the TFX ModelValidator tools to specify performance metrics for production readiness
B.
Use k-fold cross-validation as a validation strategy to ensure that your model is ready for production.
C.
Use the last relevant week of data as a validation set to ensure that your model is performing accurately on current data
D.
Use the entire dataset and treat the area under the receiver operating characteristics curve (AUC ROC) as the main metric.

You work on a growing team of more than 50 data scientists who all use Al Platform. You are
designing a strategy to organize your jobs, models, and versions in a clean and scalable way. Which
strategy should you choose?
Select the answer
1 correct answer
A.
Set up restrictive I AM permissions on the Al Platform notebooks so that only a single user or group can access a given instance.
B.
Separate each data scientist's work into a different project to ensure that the jobs, models, and versions created by each data scientist are accessible only to that user.
C.
Use labels to organize resources into descriptive categories. Apply a label to each created resource so that users can filter the results by label when viewing or monitoring the resources
D.
Set up a BigQuery sink for Cloud Logging logs that is appropriately filtered to capture information about Al Platform resource usage In BigQuery create a SQL view that maps users to the resources they are using.

Quiz

During batch training of a neural network, you notice that there is an oscillation in the loss. How
should you adjust your model to ensure that it converges?
Select the answer
1 correct answer
A.
Increase the size of the training batch
B.
Decrease the size of the training batch
C.
Increase the learning rate hyperparameter
D.
Decrease the learning rate hyperparameter

Quiz

You are building a linear model with over 100 input features, all with values between -1 and 1. You
suspect that many features are non-informative. You want to remove the non-informative features
from your model while keeping the informative ones in their original form. Which technique should
you use?
Select the answer
1 correct answer
A.
Use Principal Component Analysis to eliminate the least informative features.
B.
Use L1 regularization to reduce the coefficients of uninformative features to 0.
C.
After building your model, use Shapley values to determine which features are the most informative.
D.
Use an iterative dropout technique to identify which features do not degrade the model when removed.

Quiz

Your team has been tasked with creating an ML solution in Google Cloud to classify support requests
for one of your platforms. You analyzed the requirements and decided to use TensorFlow to build the
classifier so that you have full control of the model's code, serving, and deployment. You will use
Kubeflow pipelines for the ML platform. To save time, you want to build on existing resources and
use managed services instead of building a completely new model. How should you build the
classifier?
Select the answer
1 correct answer
A.
Use the Natural Language API to classify support requests
B.
Use AutoML Natural Language to build the support requests classifier
C.
Use an established text classification model on Al Platform to perform transfer learning
D.
Use an established text classification model on Al Platform as-is to classify support requests

You are building a linear regression model on BigQuery ML to predict a customer's likelihood of
purchasing your company's products. Your model uses a city name variable as a key predictive
component. In order to train and serve the model, your data must be organized in columns. You want
to prepare your data using the least amount of coding while maintaining the predictable variables.
What should you do?
Select the answer
1 correct answer
A.
Create a new view with BigQuery that does not include a column with city information
B.
Use Dataprep to transform the state column using a one-hot encoding method, and make each city a column with binary values.
C.
Use Cloud Data Fusion to assign each city to a region labeled as 1, 2, 3, 4, or 5r and then use that number to represent the city in the model.
D.
Use TensorFlow to create a categorical variable with a vocabulary list Create the vocabulary file, and upload it as part of your model to BigQuery ML.
