Dialogue as a sequential decision making process
Abstract
Endowing computers with the ability to conduct natural conversation has been a core problem of AI ever since Turing postulated what was latter dubbed ‘the Turing Test’ in the 1950s. Since then two research paths have emerged. The aim of the first approach is to model chit-chat, conversations with no particular purpose. The aim of the second approach is to model task-oriented dialogues, conversations geared towards a particular goal. An elegant framework for this gaol-oriented approach is to view a dialogue as a sequential decision-making process, in which the system learns to talk to the user in such a way that the goal of the conversation is reached. In this talk, I will explain the basics of this learning mechanism, which is applicable to a wide range of interactive learning problems.
