Optimizing Interactive Systems with Data-Driven Objectives

Ziming Li
2019 Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence  
It is promising if we model the objectives directly from the user interactions which we use to optimize interactive systems, which will improve user experience and dynamically reacts to user actions.  ...  Generally, such objectives are manually crafted and rarely capture complex user needs in an accurate manner. We propose to infer the objective directly from observed user interactions.  ...  Following Assumption 3, system designers have control over the sets S, A, and the transition distribution, T , and T can be changed to optimize an interactive system.  ...
