Answer key: AI Domains

(b) Regression – Classification would answer with a label like “hot” or “cold”.
(a) Classification – The model learned from emails already labelled by people.
(c) Clustering – Finding groups without labels is clustering.
(b) Computer vision – It finds the plate in the image and reads the characters.
(b) Natural language processing – It then writes a reply in natural language.
(a) Classification learns from labelled examples; clustering finds groups without labels – So the difference is labelled versus unlabelled data.
