Remembering to Be Fair: Non-Markovian Fairness in Sequential Decision Making

no code implementations8 Dec 2023 Parand A. Alamdari, Toryn Q. Klassen, Elliot Creager, Sheila A. McIlraith

In this paper we investigate the notion of fairness in the context of sequential decision making where multiple stakeholders can be affected by the outcomes of decisions.

Noisy Symbolic Abstractions for Deep RL: A case study with Reward Machines

no code implementations20 Nov 2022 Andrew C. Li, Zizhao Chen, Pashootan Vaezipoor, Toryn Q. Klassen, Rodrigo Toro Icarte, Sheila A. McIlraith

Natural and formal languages provide an effective mechanism for humans to specify instructions and reward functions.

Learning to Follow Instructions in Text-Based Games

1 code implementation8 Nov 2022 Mathieu Tuli, Andrew C. Li, Pashootan Vaezipoor, Toryn Q. Klassen, Scott Sanner, Sheila A. McIlraith

Text-based games present a unique class of sequential decision making problem in which agents interact with a partially observable, simulated environment via actions and observations conveyed through natural language.

Learning Reward Machines: A Study in Partially Observable Reinforcement Learning

no code implementations17 Dec 2021 Rodrigo Toro Icarte, Ethan Waldie, Toryn Q. Klassen, Richard Valenzano, Margarita P. Castro, Sheila A. McIlraith

Here we show that RMs can be learned from experience, instead of being specified by the user, and that the resulting problem decomposition can be used to effectively solve partially observable RL problems.

Be Considerate: Objectives, Side Effects, and Deciding How to Act

no code implementations4 Jun 2021 Parand Alizadeh Alamdari, Toryn Q. Klassen, Rodrigo Toro Icarte, Sheila A. McIlraith

We endow RL agents with the ability to contemplate such impact by augmenting their reward based on expectation of future return by others in the environment, providing different criteria for characterizing impact.

Reward Machines: Exploiting Reward Function Structure in Reinforcement Learning

3 code implementations6 Oct 2020 Rodrigo Toro Icarte, Toryn Q. Klassen, Richard Valenzano, Sheila A. McIlraith

First, we propose reward machines, a type of finite state machine that supports the specification of reward functions while exposing reward function structure.

Towards the Role of Theory of Mind in Explanation

no code implementations6 May 2020 Maayan Shvo, Toryn Q. Klassen, Sheila A. McIlraith

Theory of Mind is commonly defined as the ability to attribute mental states (e. g., beliefs, goals) to oneself, and to others.
