Description

X5 uses text messages to encourage customers to shop more. Sending texts is costly, so we would like to target a specific group of clients, typically those who would see this as a compelling event. In other words, the goal is to target those customers who wouldn’t have made a purchase without this communication. The goal is to develop an algorithm that predicts whether or not we should send a text message to the client.

This is called uplift modeling problem, see this video for more details (video is in Russian, you can use auto subtitles).

Quality criteria

In uplift modeling tasks, clients from the test sample are ranked using descending predicted communication efficiency. The top 30% are selected from such a ranked list as the “most promising” sub-sample. This sub-sample is used to estimate the average added conversion. In a sense, we calculate the average increase in response to the impact on a client.
