Project Title

Medical Insurance Cost Prediction Using Machine Learning with Python

Domain

Python | Artificial Intelligence (AI) | Machine Learning (ML) | Healthcare Analytics | Data Science | Predictive Analytics

Project Level

Beginner to Intermediate

Project Objective

Medical insurance companies determine premium costs based on various factors such as age, gender, BMI, smoking habits, and medical history. Accurate prediction of insurance charges helps insurance providers assess risk and offer appropriate policies. The objective of this project is to build an intelligent Machine Learning model capable of predicting medical insurance costs based on customer information.

Students will learn the complete Machine Learning workflow, including data collection, preprocessing, exploratory data analysis, feature engineering, model training, testing, evaluation, and prediction. This project provides practical exposure to Artificial Intelligence, Healthcare Analytics, and Predictive Modeling concepts used in the insurance industry.
