Question 180
A cloud ML change request describes the following issue: An ML engineer needs to rapidly baseline a supported text classifier from a pretrained model before deciding whether to build a model from scratch. Which action best addresses the actual requirement?
- Select a task-compatible pretrained model in SageMaker JumpStart and evaluate it on owned data.
- Apply unsupervised clustering such as K-means on appropriately standardized features.
- Use a managed image-labeling API such as Rekognition for supported generic categories.
- Use logistic regression with calibrated probabilities as an interpretable binary-classification baseline.
Explanation
Correct Answer
A:This action fits the situation: An ML engineer needs to rapidly baseline a supported text classifier from a pretrained model before deciding whether to build a model from scratch. It implements the needed technical control: Select a task-compatible pretrained model in SageMaker JumpStart and evaluate it on owned data. The intended outcome is that the team can test an existing starting point with reduced model-development effort. The important limitation is that available model licenses and required instance capacity differ by artifact.
