How to select random data for 2 different recommender systems?












0












$begingroup$


The business problems : we have 2 different vendors that offer personalized recommender engine and want to do A/B testing with them. The recommendation would give the user a personalized offer via a push message on the phone. During the testing period, we should give each provider a dataset with different details regarding the customers (purchase history, in-app events etc). Each vendor will receive a dataset with identical info but for different clients.



What is the best method to choose the 2 datasets so that they would be similar in terms of client behaviour?



I assumed that giving them random data from our database wouldn't be a rigorous method so one idea that I have in mind is applying dbScan clustering on our database and further randomly picking clients from each cluster - don't know is this is the best approach. The full database has 200k clients and each dataset should contain 5k clients.



ex: after dbScan clustering there are k = 10 clusters so I randomly pick elements from each cluster and split them in Dataset01 and Dataset02



Any suggestions?
