A Machine Learning Optimal Pricing
Causal Inference is widely used in Gojek to provide targeted promotions for our customers. The goal is to identify the right promotions to give to a target population to maximize business objectives within certain constraints. In this presentation, we will cover the applications of SOTA algorithm, HICI and GANITE to the Demand Generation Team in Gojek.
Gojek’s Causal Inference Based Spending Engine
Finding the optimal price for rides can be a difficult task when you only get one chance to show users a price. In this talk we’ll look at the general theory behind two approaches we have used at Gojek – contextual bandits and causal inference models.
