Question
Consider the learning problems listed below. In each case, specify whether the prob- lem in question is a supervised learning problem or an unsupervised learning prob- lem. If you decide that a problem is supervised, specify whether it is a regression problem or a classification problem (a) An emergency room in a hospital measures 17 variables (blood pressure, heart rate, age, etc) for admitted patients. Then, upon seeing the patient, an ER doctor makes a decision whether to place the patient in an ICU (intensive care unit). The hospital has been recording ER data for many years. A data science team is asked to design a system that, based on the recorded data, predicts whether a newly admitted patient should be placed on an ICU or not. (b) An online video streaming company wants to streamline its website by organizing the videos in its database in groups according to reasonable shared features. (c) A real estate company collects data about the housing market in Portland, Ore- gon. The company records details about properties on the market (square footage, number of rooms, proximity to schools, year built, etc) as well as the selling prices The company wants use this recorded data in order to build an automatic system predicting a reasonable market price for a newly listed propertyExplanation / Answer
(a) - Problem mentioned is supervised learning algorithm and it is classification problem because output variable has qualitative output.(e.g., logistic regression)
(b)-Problem mentioned is Unsupervised learning because labeled data is not given.
(c)-Problem mentioned is Supervised learning because labeled data is given and it is Regression problem.
(d)-Problem mentioned is Supervised learning and it is Classification problem.
