A health insurer in Pune has records of 50,000 past policyholders, each with age, BMI, smoking status and a recorded label showing whether a hospitalisation claim above ₹2 lakh occurred in the year. It wants a model to predict this label for new applicants. Which type of machine learning does this describe?

This is supervised learning. The insurer has labelled historical data, with a known claim outcome for each policyholder, and wants to predict that outcome for new applicants. Using inputs to predict a known target is the defining feature of supervised learning, and here it is a classification problem.

Explanation

The data include a known target label (claim above ₹2 lakh or not) for each past case, and the goal is to predict that label for new cases. Learning from labelled examples is supervised learning, here a classification task. Unsupervised methods like clustering or PCA do not use a response label.
