This paper presents the notion of Virtue Signalling, a second order normative constraint that asks agents to perform actions that are unambiguously permissible. We discuss different definitions for Virtue Signalling, and show how this type of constraints can affect the behaviour of a robotic agent.

In semester 2, HMI RFs Alban Grastien and Atoosa Kasirzadeh are teaching a course entitled "Advanced Topics on Artificial Intelligence" in the Research School of Computer Science at the ANU. This course presents some of the techniques developed in AI for decision making under uncertainty, and introduces the variety of moral and sociological implications of these decisions.

We propose a constraint on machine behaviour: that partially observed machine systems ought to reassure observers that they understand the constraints that they are under and that they have and will abide by those constraints. Specifically, a system should not follow a course of action that, from the point of view of the observer, is not easily distinguishable from a course of action that is forbidden.

In this paper, published in Artificial Intelligence, Alban Grastien and co-author address the problem of conformant planning, which consists in finding a sequence of actions in a well-specified environment that achieves a specified goal despite uncertainty on the initial configuration and without using observations.

In a counterexample based approach to conformant planning, choosing the right counterexample can improve performance. We formalise this observation by introducing the notion of “superiority” of a counterexample over another one,that holds whenever the superior counterexample exhibits more tags than the latter. We provide a theoretical explanation that supports the strategy of searching for maximally superior counterexamples, and we show how this strategy can be implemented. The empirical experiments validate our approach.
