AWS Certified AI Practitioner AIF-C01 Practice Question
When preparing data for a supervised machine-learning project, you must decide whether a dataset is labeled or unlabeled. Which of the following datasets would be classified as unlabeled?
A set of audio clips, each accompanied by a textual transcript of the spoken words
A CSV file listing car features with an additional column indicating each car's market price
A folder of raw images without any tags or annotations
A collection of customer emails that are individually marked as spam or not spam
Labeled data contain both the input examples and the desired outputs (labels) that a model should learn to predict. A CSV file with a price column, audio clips with transcripts, and emails tagged as spam all include such labels. A folder of raw images with no tags or annotations provides only the inputs, so it is unlabeled and cannot be used directly for supervised learning without additional labeling work.
