You have trained three different models on your data set using Oracle AutoML. You want to visualize the behavior of each of the models, including the baseline model, on the test set. Which class should be used from the Accelerated Data Science (ADS) SDK to visually compare the models?
A. ADS Explainer
B. ADS Evaluator
C. ADSTuner
D. EvaluationMetrics
While reviewing your data, you discover that your data set has a class imbalance. You are aware that the Accelerated Data Science (ADS) SDK provides multiple built-in automatic transformation tools for data set transformation. Which would be the right tool to correct any imbalance between the classes?
A. sample()
B. suggeste_recoomendations()
C. auto_transform()
D. visualize_transforms()
During a job run, you receive an error message that no space is left on your disk device. To solve the problem, you must increase the size of the job storage. What would be the most effi-cient way to do this with Data Science Jobs?
A. On the job run, set the environment variable that helps increase the size of the storage.
B. Your code using too much disk space. Refactor the code to identify the problem.
C. Edit the job, change the size of the storage of your job, and start a new job run.
D. Create a new job with increased storage size and then run the job.
You have developed a model training code that regularly checks for new data in Object Storage and retrains the model. Which statement best describes the Oracle Cloud Infrastructure (OCI) services that can be accessed from Data Science Jobs?
A. Data Science Jobs can access OCI resources only via the resource principal.
B. Some OCI services require authorizations not supported by Data Science Jobs.
C. Data Science Jobs cannot access all OCI services.
D. Data Science Jobs can access all OCI services.
Which Oracle Accelerated Data Science (ADS) classes can be used for easy access to data sets from reference libraries and index websites, such as scikit-learn?
A. ADSTurner
B. DatasetFactory
C. SecretKeeper
D. Dataset Browser
Six months ago, you created and deployed a model that predicts customer churn for a call center. Initially, it was yielding quality predictions. However, over the last two months, users have been questioning the credibility of the predictions. Which TWO methods customer churn would you employ to verify the accuracy of the model?
A. Redeploy the model
B. Retrain the model
C. Operational monitoring
D. Validate the model using recent data
E. Drift monitoring
Where do calls to stdout and stderr from score.py go in a model deployment?
A. The predict log in the Oracle Cloud Infrastructure (OCI) Logging service as defined in the deployment.
B. The OCI Cloud Shell, which can be accessed from the console.
C. The file that was defined for them on the Virtual stachine (VM).
D. The OCI console.
The Accelerated Data Science (ADS) model evaluation classes support different types of ma-chine learning modeling techniques
Which THREE types of modeling techniques are supported by ADS Evaluators?
A. Recurrent Neural Network
B. Regression Analysis
C. Principal Component Analysis
D. Binary Classification
E. Multiclass Classification
F. K-Means Clustering
You are a data scientist with a set of text and image files that need annotation, and you want to use Oracle Cloud Infrastructure (OCI) Data Labeling. Which of the following THREE an-notation classes are supported by the tool.?
A. Object Detection
B. Named Entity Extraction
C. Classification (single/multi label)
D. Key-Point and Landmark
E. Polygonal Segmentation
F. Semantic Segmentation
