Discovering Conceptual Knowledge with Analytic Ontology Templates for Articulated Objects

AAAI 2025technical

Human cognition can leverage fundamental conceptual knowledge, like geometry and kinematic ones, to appropriately perceive, comprehend and interact with novel objects. Motivated by this finding, we aim to endow machine intelligence with an analogous capability through performing at the conceptual le…

Stimulus Verification Is a Universal and Effective Sampler in Multi-Modal Human Trajectory Prediction

CVPR 2023poster

To comprehensively cover the uncertainty of the future, the common practice of multi-modal human trajectory prediction is to first generate a set/distribution of candidate future trajectories and then sample required numbers of trajectories from them as final predictions. Even though a large number…

Human Trajectory Prediction With Momentary Observation

CVPR 2022poster

Human trajectory prediction task aims to analyze human future movements given their past status, which is a crucial step for many autonomous systems such as self-driving cars and social robots. In real-world scenarios, it is unlikely to obtain sufficiently long observations at all times for predicti…
