A Stochastic Differential Equation Framework for Guiding Online User Activities in Closed Loop

AISTATS 2018poster

Recently, there is a surge of interest in using point processes to model continuous-time user activities. This framework has resulted in novel models and improved performance in diverse applications. However, most previous works focus on the ”open loop” setting where learned models are used for pred…
