Exam AI-900 topic 1 question 44 discussion

the brain haemorrhage types are predefined (labeled), so it's classification

This is classification. There are multiple reasons it's classification - The training data is already tagged as with the correct type of hemorrhage - Classification can be done for more than two classes (which people seem to not realize based on the comments) - You do clustering on a group of inputs. For example, the scans of 10 people. You can't cluster a single input. Clearly you get a new scan of a new patient and you want to know what that scan shows, you don't have a group of scans to cluster. - Clustering gives NO labels. You just get groups and don't know what the label is, but in this question it's very clear they want to know the label that belongs to the new scan -> classification
