In recent times shopping malls and Super-mart started keeping track of their sales data of each and every individual items for predicting future demand of the customer and update the inventory management as well. Various algorithms have been implemented, sales have been predicted with the help of various items. Collected data items have been analyze based on their properties which will further help in high level of prediction accuracy. Machine learning algorithms make software applications more accurate in Predicting outcomes without being clearly programmed. There are various different models applied in different areas and trained to reach the target. This project predicts the future sales of Mega Mart Companies keeping in view the sales of previous years. A comparative study of Sales prediction is done using Machine Learning models such as Linear Regression, Light GBM, Decision Tree, XGBoost Regressor, Random Forest Regressor, Gradient Boosting. The prediction includes data parameters such as item_MRP, Outlet_type, Outlet_location, Outlet_size, Outlet_Establishment_Year, Outlet_Identifier, Item_Type. Sales prediction is meant to help business owners decide which approach to use when predicting the sales of their supermarket based on different scenarios.
