Are Large Language Models Aligned with People's Social Intuitions for Human-Robot Interactions?

1 code implementation8 Mar 2024 Lennart Wachowiak, Andrew Coles, Oya Celiktutan, Gerard Canal

We find that GPT-4 strongly outperforms other models, generating answers that correlate strongly with users' answers in two studies $\unicode{x2014}$ the first study dealing with selecting the most appropriate communicative act for a robot in various situations ($r_s$ = 0. 82), and the second with judging the desirability, intentionality, and surprisingness of behavior ($r_s$ = 0. 83).

Cross Domain Policy Transfer with Effect Cycle-Consistency

no code implementations4 Mar 2024 Ruiqi Zhu, Tianhong Dai, Oya Celiktutan

Unlike prior methods that rely on paired data, we propose a novel approach for learning the mapping functions between state and action spaces across domains using unpaired data.

Learning to Solve Tasks with Exploring Prior Behaviours

1 code implementation6 Jul 2023 Ruiqi Zhu, Siyuan Li, Tianhong Dai, Chongjie Zhang, Oya Celiktutan

Our method can endow agents with the ability to explore and acquire the required prior behaviours and then connect to the task-specific behaviours in the demonstration to solve sparse-reward tasks without requiring additional demonstration of the prior behaviours.

A Simple Recipe to Meta-Learn Forward and Backward Transfer

no code implementations ICCV 2023 Edoardo Cetin, Antonio Carta, Oya Celiktutan

Meta-learning holds the potential to provide a general and explicit solution to tackle interference and forgetting in continual learning.

Neural Weight Search for Scalable Task Incremental Learning

1 code implementation24 Nov 2022 Jian Jiang, Oya Celiktutan

Task incremental learning aims to enable a system to maintain its performance on previously learned tasks while learning new tasks, solving the problem of catastrophic forgetting.

Policy Gradient With Serial Markov Chain Reasoning

no code implementations13 Oct 2022 Edoardo Cetin, Oya Celiktutan

We model agent behavior as the steady-state distribution of a parameterized reasoning Markov chain (RMC), optimized with a new tractable estimate of the policy gradient.

Automatic Context-Driven Inference of Engagement in HMI: A Survey

no code implementations30 Sep 2022 Hanan Salam, Oya Celiktutan, Hatice Gunes, Mohamed Chetouani

An integral part of seamless human-human communication is engagement, the process by which two or more participants establish, maintain, and end their perceived connection.

GROWL: Group Detection With Link Prediction

no code implementations8 Nov 2021 Viktor Schmuck, Oya Celiktutan

Our proposed method, GROup detection With Link prediction (GROWL), demonstrates the effectiveness of a GNN based approach.

Forecasting Nonverbal Social Signals during Dyadic Interactions with Generative Adversarial Neural Networks

1 code implementation18 Oct 2021 Nguyen Tan Viet Tuyen, Oya Celiktutan

Along with verbal communication, successful social interaction is closely coupled with the interplay between nonverbal perception and action mechanisms, such as observation of gaze behaviour and following their attention, coordinating the form and function of hand gestures.

Learning Pessimism for Robust and Efficient Off-Policy Reinforcement Learning

no code implementations7 Oct 2021 Edoardo Cetin, Oya Celiktutan

Off-policy deep reinforcement learning algorithms commonly compensate for overestimation bias during temporal-difference learning by utilizing pessimistic estimates of the expected target returns.

Learning Routines for Effective Off-Policy Reinforcement Learning

no code implementations5 Jun 2021 Edoardo Cetin, Oya Celiktutan

Within our framework, agents learn effective behavior over a routine space: a new, higher-level action space, where each routine represents a set of 'equivalent' sequences of granular actions with arbitrary length.

IB-DRR: Incremental Learning with Information-Back Discrete Representation Replay

no code implementations21 Apr 2021 Jian Jiang, Edoardo Cetin, Oya Celiktutan

However, finding a trade-off between the model performance and the number of samples to save for each class is still an open problem for replay-based incremental learning and is increasingly desirable for real-life applications.

Domain-Robust Visual Imitation Learning with Mutual Information Constraints

1 code implementation ICLR 2021 Edoardo Cetin, Oya Celiktutan

Human beings are able to understand objectives and learn by simply observing others perform a task.
