Grocery Sales Forecast: Weekend Hackathon #4

The 4th instalment of weekend hackathon series is here, and this time we challenge data scientists to forecast the sales of grocery items in MachineHack’s Grocery Sales Forecast: Weekend Hackathon #4.

The challenge will start on May 8th Friday at 6 pm IST.

Problem Statement & Description

Sales forecasting has always been one of the most predominant applications of machine learning. Big companies like Walmart have been employing this technique to achieve steady and enormous growth over decades now. In this challenge, you as a data scientist must use machine learning to help a small grocery store in predicting its future sales and making better business decisions.

Given the daily sales of a grocery shop recorded over a period of almost 2 years, your objective as a data scientist is to build a machine learning model that can forecast the sales for the upcoming 3 months.

You are provided with the recorded observation of daily sales of a grocery shop over a period of 692 days to forecast the sales of the next 90 days.

Data Description

The unzipped folder will have the following files.

  • Train.csv – 692 observations
  • Test.csv – 90 observations
  • Sample Submission – Sample format for the submission

Target Variable: GrocerySales

The datasets will be made available for download on May 8th, Friday at 6 pm IST

Below are the file formats for the provided data
