Mathematical Model for Processing Multi-user Requests on POMDP Hybrid Dialog Management
Sangjun Koo, Gary Geunbae Lee, Hwanjo Yu · 2016
We present a mathematical model that integrates multiparty/multimodal components with a stochastic dialog model based on a partially observable Markov decision process (POMDP). Our suggested model consists of three subcomponents: a discrete input streamer, a dialog stack manager, and a back-end dialog system. The discrete input streamer extracts discrete hypotheses from input streams, while the dialog stack manager manages several dialog stacks. The back-end dialog system selects a proper system action by using hybrid POMDP model. We introduce our hybrid POMDP architecture which can be extended to advanced interface systems such as those used in drones and mobile applications.
