THE COLOSSEUM: A Benchmark for Evaluating Generalization for Robotic Manipulation

1 code implementation13 Feb 2024 Wilbert Pumacay, Ishika Singh, Jiafei Duan, Ranjay Krishna, Jesse Thomason, Dieter Fox

To realize effective large-scale, real-world robotic applications, we must evaluate how well our robot policies adapt to changes in environmental conditions.

Selective Visual Representations Improve Convergence and Generalization for Embodied AI

no code implementations7 Nov 2023 Ainaz Eftekhar, Kuo-Hao Zeng, Jiafei Duan, Ali Farhadi, Ani Kembhavi, Ranjay Krishna

Inspired by selective attention in humans-the process through which people filter their perception based on their experiences, knowledge, and the task at hand-we introduce a parameter-efficient approach to filter visual stimuli for embodied AI.

AR2-D2:Training a Robot Without a Robot

no code implementations23 Jun 2023 Jiafei Duan, Yi Ru Wang, Mohit Shridhar, Dieter Fox, Ranjay Krishna

By contrast, we introduce AR2-D2: a system for collecting demonstrations which (1) does not require people with specialized training, (2) does not require any real robots during data collection, and therefore, (3) enables manipulation of diverse objects with a real robot.

Robustness of Utilizing Feedback in Embodied Visual Navigation

no code implementations6 Mar 2023 Jenny Zhang, Samson Yu, Jiafei Duan, Cheston Tan

This paper presents a framework for training an agent to actively request help in object-goal navigation tasks, with feedback indicating the location of the target object in its field of view.

BOSS: A Benchmark for Human Belief Prediction in Object-context Scenarios

no code implementations21 Jun 2022 Jiafei Duan, Samson Yu, Nicholas Tan, Li Yi, Cheston Tan

Humans with an average level of social cognition can infer the beliefs of others based solely on the nonverbal communication signals (e. g. gaze, gesture, pose and contextual information) exhibited during social interactions.

Good Time to Ask: A Learning Framework for Asking for Help in Embodied Visual Navigation

1 code implementation20 Jun 2022 Jenny Zhang, Samson Yu, Jiafei Duan, Cheston Tan

In reality, it is often more efficient to ask for help than to search the entire space to find an object with an unknown location.

ABCDE: An Agent-Based Cognitive Development Environment

no code implementations10 Jun 2022 Jieyi Ye, Jiafei Duan, Samson Yu, Bihan Wen, Cheston Tan

How can the most common 1, 000 concepts (89\% of everyday use) be learnt in a naturalistic children's setting?

A Survey on Machine Learning Approaches for Modelling Intuitive Physics

no code implementations14 Feb 2022 Jiafei Duan, Arijit Dasgupta, Jason Fischer, Cheston Tan

Despite the wide range of work in physical reasoning for machine cognition, there is a scarcity of reviews that organize and group these deep learning approaches.

A Benchmark for Modeling Violation-of-Expectation in Physical Reasoning Across Event Categories

no code implementations16 Nov 2021 Arijit Dasgupta, Jiafei Duan, Marcelo H. Ang Jr, Yi Lin, Su-hua Wang, Renée Baillargeon, Cheston Tan

Recent work in computer vision and cognitive reasoning has given rise to an increasing adoption of the Violation-of-Expectation (VoE) paradigm in synthetic datasets.

AVoE: A Synthetic 3D Dataset on Understanding Violation of Expectation for Artificial Cognition

1 code implementation12 Oct 2021 Arijit Dasgupta, Jiafei Duan, Marcelo H. Ang Jr, Cheston Tan

Recent work in cognitive reasoning and computer vision has engendered an increasing popularity for the Violation-of-Expectation (VoE) paradigm in synthetic datasets.

PIP: Physical Interaction Prediction via Mental Simulation with Span Selection

no code implementations10 Sep 2021 Jiafei Duan, Samson Yu, Soujanya Poria, Bihan Wen, Cheston Tan

However, there is a lack of intuitive physics models that are tested on long physical interaction sequences with multiple interactions among different objects.

SPACE: A Simulator for Physical Interactions and Causal Learning in 3D Environments

2 code implementations13 Aug 2021 Jiafei Duan, Samson Yu Bai Jian, Cheston Tan

We then further evaluate it with a state-of-the-art physics-based deep model and show that the SPACE dataset improves the learning of intuitive physics with an approach inspired by curriculum learning.
