HamiFormer: Dual-Expert Diffusion Fields with Affine Symplectic Maps
Haoxiang Huang, Xiang Liu, Shuwei Wang +2
Predicting smooth dynamics and collisions requires modeling continuous evolution and abrupt state changes. We introduce HamiFormer, a dual-expert diffusion field combining whole-wi…

GeoCo-SAVi: Geometry-Consistent Slot Attention for Explicitly Editable Object Representations
Haoxiang Huang, Zhekai Wang, Xiang Liu +6
Object-centric video models represent scenes with slots, yet exposed geometry can vary in meaning with appearance. In Invariant Slot Attention (ISA), explicit position and scale ca…

MOSH-WM: Mask-Grounded Soft-Hamiltonian Dynamics for Object-Centric World Models
Zhekai Wang, Haoxiang Huang, Xiang Liu +6
Object-centric world models forecast future videos by evolving a set of entity slots, but the variables receiving dynamics supervision are often unconstrained visual features. We i…
