Sales Advancer uses Machine Learning to create custom Recommender Systems to increase your sales. How does it work? At every purchase we recommend customers to buy additional items that fit them personally. Based on the customer's past behavior, we can learn what kind of products is appropriate. The Recommender System provides three kinds of services: 1) Personal Recommendation: Given the Customer ID, provide a list of products that fit this customer personally. 2) Similar Products: Given the product ID, provide a list of the most similar products. 3) Popular Products: Given a period of time, provide a list of the products sold the most.
