I'm trying to build a recommendation system and I am trying to use Collaborative Filtering (please let me know if other models fit better for my use case).
My data is for an e-commerce site where I have some data on Transactions. I have another table which gives me some product features.
Transaction Table includes:
CustomerID, ProductID, OrderID, Units Bought, Revenue, Purchase Country
Most Collaborative Filtering articles/examples I've seen use Product Ratings and Time (Purchase/Transaction Timestamp) and I don't have these 2 features available.
Question & Goal
Can I use a normal CF model when I don't have product ratings? How would I implement it?
Also, does the model just utilize customer preferences individually or does it also account for items that were purchased together (can be determined with orderID). If not, how do I make a model that uses that information as well?
