Data-Driven Goal Recognition Design for General Behavioral Agents

no code implementations3 Apr 2024 Robert Kasumba, Guanghui Yu, Chien-Ju Ho, Sarah Keren, William Yeoh

Following existing literature, we use worst-case distinctiveness ($\textit{wcd}$) as a measure of the difficulty in inferring the goal of an agent in a decision-making environment.

Selectively Sharing Experiences Improves Multi-Agent Reinforcement Learning

1 code implementation NeurIPS 2023 Matthias Gerstgrasser, Tom Danino, Sarah Keren

We present a novel multi-agent RL approach, Selective Multi-Agent Prioritized Experience Relay, in which agents share with other agents a limited number of transitions they observe during training.

Value of Assistance for Grasping

no code implementations22 Oct 2023 Mohammad Masarwy, Yuval Goshen, David Dovrat, Sarah Keren

In multiple realistic settings, a robot is tasked with grasping an object without knowing its exact pose and relies on a probabilistic estimation of the pose to decide how to attempt the grasp.

Value of Assistance for Mobile Agents

1 code implementation23 Aug 2023 Adi Amuzig, David Dovrat, Sarah Keren

In some settings, it may be possible to perform assistive actions that reduce uncertainty about a robot's location.

Contextual Pre-planning on Reward Machine Abstractions for Enhanced Transfer in Deep Reinforcement Learning

1 code implementation11 Jul 2023 Guy Azran, Mohamad H. Danesh, Stefano V. Albrecht, Sarah Keren

Recent studies show that deep reinforcement learning (DRL) agents tend to overfit to the task on which they were trained and fail to adapt to minor environment changes.

Explainable Reinforcement Learning via Model Transforms

1 code implementation24 Sep 2022 Mira Finkelstein, Lucy Liu, Nitsan Levy Schlot, Yoav Kolumbus, David C. Parkes, Jeffrey S. Rosenshein, Sarah Keren

This has given rise to a variety of approaches to explainability in RL that aim to reconcile discrepancies that may arise between the behavior of an agent and the behavior that is anticipated by an observer.

Collaboration Promotes Group Resilience in Multi-Agent AI

no code implementations12 Nov 2021 Sarah Keren, Matthias Gerstgrasser, Ofir Abu, Jeffrey Rosenschein

AI agents need to be robust to unexpected changes in their environment in order to safely operate in real-world scenarios.

Designing Environments Conducive to Interpretable Robot Behavior

no code implementations2 Jul 2020 Anagha Kulkarni, Sarath Sreedharan, Sarah Keren, Tathagata Chakraborti, David Smith, Subbarao Kambhampati

Given structured environments (like warehouses and restaurants), it may be possible to design the environment so as to boost the interpretability of the robot's behavior or to shape the human's expectations of the robot's behavior.
