You have a large corpus of written support cases that can be classified into 3 separate categories: Technical Support, Billing Support, or Other Issues. You need to quickly build, test, and deploy a service that will automatically classify future written requests into one of the categories. How should you configure the pipeline?
A. Use the Cloud Natural Language API to obtain metadata to classify the incoming cases.
B. Use AutoML Natural Language to build and test a classifier. Deploy the model as a REST API.
C. Use BigQuery ML to build and test a logistic regression model to classify incoming requests. Use BigQuery ML to perform inference.
D. Create a TensorFlow model using Google's BERT pre-trained model. Build and test a classifier, and deploy the model using Vertex AI.
You work for a large social network service provider whose users post articles and discuss news. Millions of comments are posted online each day, and more than 200 human moderators constantly review comments and flag those that are inappropriate. Your team is building an ML model to help human moderators check content on the platform. The model scores each comment and flags suspicious comments to be reviewed by a human. Which metric(s) should you use to monitor the model's performance?
A. Number of messages flagged by the model per minute
B. Number of messages flagged by the model per minute confirmed as being inappropriate by humans.
C. Precision and recall estimates based on a random sample of 0.1% of raw messages each minute sent to a human for review
D. Precision and recall estimates based on a sample of messages flagged by the model as potentially inappropriate each minute
You are an ML engineer at a bank that has a mobile application. Management has asked you to build an ML-based biometric authentication for the app that verifies a customer's identity based on their fingerprint. Fingerprints are considered highly sensitive personal information and cannot be downloaded and stored into the bank databases. Which learning strategy should you recommend to train and deploy this ML mode?
A. Data Loss Prevention API
B. Federated learning
C. MD5 to encrypt data
D. Differential privacy
