Question 351
You are using Azure Machine Learning designer to create a training pipeline for a binary classification model. You have added a dataset containing features and labels, a Two-Class Decision Forest module, and a Train Model module. You plan to use Score Model and Evaluate Model modules to test the trained model with a subset of the dataset that was not used for training. Which additional kind of module should you add?
Answer
Split Data
Question 352
You use an Azure Machine Learning designer pipeline to train and test a binary classification model. You review the model’s performance metrics in an Evaluate Model module, and note that it has an AUC score of 0.3. What can you conclude about the model?
Answer
The model performs worse than random guessing.
Question 353
You use Azure Machine Learning designer to create a training pipeline for a classification model. What must you do before deploying the model as a service?
Answer
Create an inference pipeline from the training pipeline
Question 354
You are using an Azure Machine Learning designer pipeline to train and test a K-Means clustering model. You want your model to assign items to one of three clusters. Which configuration property of the K-Means Clustering module should you set to accomplish this?
Answer
Set Number of Centroids to 3
Question 355
You use Azure Machine Learning designer to create a training pipeline for a clustering model. Now you want to use the model in an inference pipeline. Which module should you use to infer cluster predictions from the model?
Answer
Assign Data to Clusters
Question 356
You plan to use the Custom Vision service to train an image classification model. You want to create a resource that can only be used for model training, and not for prediction. Which kind of resource should you create in your Azure subscription?
Answer
Custom Vision
Question 357
You train an image classification model that achieves less than satisfactory evaluation metrics. How might you improve it?
Answer
Add more images to the training set.
Question 358
You have published an image classification model. What information must you provide to developers who want to use it?
Answer
The project ID, the model name, and the key and endpoint for the prediction resource
Question 359
Which of the following results does an object detection model typically return for an image?
Answer
A class label, probability, and bounding box for each object in the image
Question 360
You plan to use a set of images to train an object detection model, and then publish the model as a predictive service. You want to use a single Azure resource with the same key and endpoint for training and prediction. What kind of Azure resource should you create?
Answer
Cognitive Services
