This retail machine learning use case can use purchase data to predict inventory needs in real-time. These algorithms can provide a daily dashboard of suggested orders to a purchasing manager based on the day of the week, the season, nearby events, social media data, and past customer behavior. In scenarios where the e-commerce platform does not manage inventories directly, we have built similar solutions to predict if an item a user is purchasing may be out of stock. As shown in this machine learning use case in retail, a predictive model leverages historical data such as past stockout events, demand, price, and stock level for each product.
