Register each user with a user ID on the Firebase Cloud Messaging server, which sends a notification when your model predicts that a user's account balance will drop below the $25 thresholdView AnswerAnswer: D Explanation: This answer is correct because it uses Firebase, a platform that provides a scalable and...

You are profiling the performance of your TensorFlow model training time and notice a performance issue caused by inefficiencies in the input data pipeline for a single 5 terabyte CSV file dataset on Cloud Storage. You need to optimize the input pipeline performance. Which action should you try first to...

You are working on a binary classification ML algorithm that detects whether an image of a classified scanned document contains a company’s logo. In the dataset, 96% of examples don’t have the logo, so the dataset is very skewed. Which metrics would give you the most confidence in your model?A...

You have written unit tests for a Kubeflow Pipeline that require custom libraries. You want to automate the execution of unit tests with each new push to your development branch in Cloud Source Repositories. What should you do?A . Write a script that sequentially performs the push to your development...

You need to train a natural language model to perform text classification on product descriptions that contain millions of examples and 100,000 unique words. You want to preprocess the words individually so that they can be fed into a recurrent neural network. What should you do?A . Create a hot-encoding...

You work for a large hotel chain and have been asked to assist the marketing team in gathering predictions for a targeted marketing strategy. You need to make predictions about user lifetime value (LTV) over the next 30 days so that marketing can be adjusted accordingly. The customer dataset is...

Your data science team is training a PyTorch model for image classification based on a pre-trained RestNet model. You need to perform hyperparameter tuning to optimize for several parameters. What should you do?A . Convert the model to a Keras model, and run a Keras Tuner job.B . Run a...

You are going to train a DNN regression model with Keras APIs using this code: How many trainable weights does your model have? (The arithmetic below is correct.)A . 501*256+257*128+2 161154B . 500*256+256*128+128*2 161024C . 501*256+257*128+128*2161408D . 500*256*0 25+256*128*0 25+128*2 40448View AnswerAnswer: B Explanation: The number of trainable weights in...
