b) Use the Integrated Gradients method to efficiently compute feature attributions for each predicted image.

c) Use PCA (Principal Component Analysis) to reduce the original feature set to a smaller set of easily understood features.

d) Use k-means clustering to group similar images together, and calculate the Davies-Bouldin index to evaluate the separation between clusters.


02. You are an ML engineer at a media company. You want to use machine learning to analyze video content, identify objects, and alert users if there is inappropriate content.

Which Google Cloud products should you use to build this project?


a) Pub/Sub, Cloud Function, Cloud Vision API

03. You work for a large financial institution that is planning to use Dialogflow to create a chatbot for the company’s mobile app.

You have reviewed old chat logs and tagged each conversation for intent based on each customer’s stated intention for contacting customer service.

About 70% of customer inquiries are simple requests that are solved within 10 intents. The remaining 30% of inquiries require much longer and more complicated requests.

Which intents should you automate first?


a) Automate a blend of the shortest and longest intents to be representative of all intents.

b) Automate the more complicated requests first because those require more of the agents’ time.
