VTInstructor: Visual Trajectory Prompting for Navigation Instruction Generation in Continuous Environments

Navigation instruction generation from ego-centric RGB video in continuous environments is an important yet challenging task for human-robot interaction and scalable dataset construction. Prior instruction generators assume discrete viewpoint graphs with panoramic observations, where trajectory structure is explicit; i...

Rethinking Contextualization by Reinterpreting Attention Head Channels

Contextualization, the core operation of language modeling, transmits information across words to build sentence-specific word representations. Prior works mainly study contextualization, focusing on individual words and attention heads as a growing discrete dictionary, lacking a global view of their general behavior....

Neuro-Symbolic Synergy for World Modeling

NeSyS alternates training between the two models using trajectories inadequately explained by the other, and prioritizes transitions that are weakly covered by symbolic rules, using 35--60% of the training pairs while outperforming full-data supervised fine-tuning in five of six settings.
