Link Representation Learning for Probabilistic Travel Time Estimation
Chen Xu, Qiang Wang, Lijun Sun
Travel time estimation is a key task in navigation apps and web mapping services. Existing deterministic and probabilistic methods, based on the assumption of trip independence, pr…
AG-Fusion: adaptive gated multimodal fusion for 3d object detection in complex scenes
Sixian Liu, Chen Xu, Qiang Wang +2
Multimodal camera-LiDAR fusion technology has found extensive application in 3D object detection, demonstrating encouraging performance. However, existing methods exhibit significa…
Likelihood-Free Variational Autoencoders
Chen Xu, Qiang Wang, Lijun Sun
Variational Autoencoders (VAEs) typically rely on a probabilistic decoder with a predefined likelihood, most commonly an isotropic Gaussian, to model the data conditional on latent…
SPTTE: A Spatiotemporal Probabilistic Framework for Travel Time Estimation
Chen Xu, Qiang Wang, Lijun Sun
Accurate travel time estimation is essential for navigation and itinerary planning. While existing research employs probabilistic modeling to assess travel time uncertainty and acc…
