For this optimization, the algorithm needs to have correct and timely information about the profits from orders. However, this is often a problem e.g. due to returned orders or due to buying the products to store only after a customer has paid for them. For this reason, the Smart Bidding Algorithm calculates with revenues, assuming the simple constant margin and constant return rate for all products. This can be improved by predicting the profits - either using a complex model for the profit or separating profit into a multiplication of revenue, margin, and return rate where revenue is known, average margin can be taken from the database, and return rate can be predicted using a binary model.",[11,613,614],{},"Azure Databricks helps you combine the necessary data both from real-time streams and a regularly updated database.
