Problem statement

Boo yeah, it’s the holiday season again! You are visiting your folks who live by the countryside. On Halloween night, their neighbors hosted a phenomenal carnival with the greatest pomp and show. People dressed up in their spookiest costumes; families went trick-or-treating; almost everyone came together to have a great time.

For the carnival, your neighbors had set up multiple stalls for entertaining their guests. When it’s your turn to host a carnival during Christmas, you wish to promote local businesses and help boost their sales. 

You plan to unleash the inner Machine Learning expert in you and build a sophisticated Machine Learning model that predicts selling prices of products based on the mentioned factors.

The dataset consists of parameters such as product and market categories, quality and demand of the product, its minimum and maximum prices, available discount applicable on the product, and the like.

The benefits of practicing this problem by using Machine Learning techniques are as follows:

  • This challenge encourages you to apply your Machine Learning skills to build a model that predicts the price of a product with given parameter values.
  • This challenge will help you enhance your knowledge of regression. Regression is one of the basic building blocks of Machine Learning.

We challenge you to build a model that successfully predicts the selling price of a given product.


Considering these unprecedented times that the world is facing due to the Coronavirus pandemic, we wish to do our bit and contribute the prize money for the welfare of society.


Machine Learning is an application of Artificial Intelligence (AI) that provides systems with the ability to automatically learn and improve from experiences without being explicitly programmed. Machine Learning is a Science that determines patterns in data. These patterns provide a deeper meaning to problems. First, it helps you understand the problems better and then solve the same with elegance.

Here’s presenting HackerEarth’s Machine Learning challenge: Carnival Wars!

This challenge is designed to help you improve your Machine Learning skills by competing and learning from fellow participants.

Why should you participate?

  • To analyze and implement multiple algorithms and determine which is more appropriate for a problem
  • To get hands-on experience in Machine Learning problems

Who should participate?

  • Working professionals
  • Data Science or Machine Learning enthusiasts
  • College students (if you understand the basics of predictive modeling)
