Consider the following possible applications of AI. Application 1: First is algorithms for combing through person profiles on internet sites like LinkedIn for the best possible match for a certain job. Application 2: Second is chatbots designed to talk to elderly retirees and help them navigate technology. Application 3: Third is algorithms that can teach robots to move better (e.g. to open a door). Application 4:Fourth is teaching an algorithm to sort peaches into grades (A-grade, B-grade, etc) Below, match the AI task to the application, i.e. for each AI task identify which application it is likely to be most central to.
