Hit-and-Run Mixes as Fast as the Ball Walk
Ruizhe Zhang
Let be an isotropic convex body. We prove that the hit-and-run walk, started from any -warm distribution, reaches total-variation distance f…
HelloWorld: Enabling Socially Interactive Characters in Video World Models
Liangyang Ouyang, Ruicong Liu, Xuangeng Chu +2
Despite the remarkable recent progress of video world models, social interaction between users and the characters within these worlds remains unsupported. To fill this gap, we pres…
