A Probabilistic-Logic based Commonsense Representation Framework for Modelling Inferences with Multiple Antecedents and Varying Likelihoods
Shantanu Jaiswal, Liu Yan, Dongkyu Choi +1
Commonsense knowledge-graphs (CKGs) are important resources towards building machines that can 'reason' on text or environmental inputs and make inferences beyond perception. While…
Improving Object Permanence using Agent Actions and Reasoning
Ying Siu Liang, Chen Zhang, Dongkyu Choi +1
Object permanence in psychology means knowing that objects still exist even if they are no longer visible. It is a crucial concept for robots to operate autonomously in uncontrolle…
Maintaining a Reliable World Model using Action-aware Perceptual Anchoring
Ying Siu Liang, Dongkyu Choi, Kenneth Kwok
Reliable perception is essential for robots that interact with the world. But sensors alone are often insufficient to provide this capability, and they are prone to errors due to v…
Direct Visual-Inertial Odometry with Semi-Dense Mapping
Wenju Xu, Dongkyu Choi, Guanghui Wang
The paper presents a direct visual-inertial odometry system. In particular, a tightly coupled nonlinear optimization based method is proposed by integrating the recent advances in…
