Starbucks-offers-recommender

This model can predict whether to send a customer an offer based on offer properties and user demographics.

Dataset

The data set used contains simulated data that mimics customer behavior on the Starbucks rewards mobile app. Once every few days, Starbucks sends out an offer to users of the mobile app. An offer can be merely an advertisement for a drink or an actual offer such as a discount or BOGO (buy one get one free). Some users might not receive any offer during certain weeks.
