The Field Knows: Cross-Dimensional Geometry from Navigation to Black Holes
Chenghao Xu
We introduce a continuous metric field framework trained by a single causal contrastive loss. The framework encodes a scene into coefficients of a fixed symmetric matrix basis, ass…
Space Is Intelligence: Neural Semigroup Superposition for Riemannian Metric Generation
Chenghao Xu
Traditional approaches place intelligence in the agent, whether as a learned policy or a search procedure. We instead place intelligence in the space itself: a scene induces a Riem…
Semantic Evidence Regulation via Relational Bias for Zero-Shot Object Navigation
Weitao An, Chenghao Xu, Xu Yang +1
Object navigation requires an embodied agent to locate a target object in an unknown environment through visual observations. Existing zero-shot methods typically leverage open-voc…
Hystar: Hypernetwork-driven Style-adaptive Retrieval via Dynamic SVD Modulation
Yujia Cai, Boxuan Li, Chenghao Xu +1
Query-based image retrieval (QBIR) requires retrieving relevant images given diverse and often stylistically heterogeneous queries, such as sketches, artworks, or low-resolution pr…
Beyond Global Alignment: Fine-Grained Motion-Language Retrieval via Pyramidal Shapley-Taylor Learning
Hanmo Chen, Guangtao Lyu, Chenghao Xu +3
As a foundational task in human-centric cross-modal intelligence, motion-language retrieval aims to bridge the semantic gap between natural language and human motion, enabling intu…
Past- and Future-Informed KV Cache Policy with Salience Estimation in Autoregressive Video Diffusion
Hanmo Chen, Chenghao Xu, Xu Yang +2
Video generation is pivotal to digital media creation, and recent advances in autoregressive video generation have markedly enhanced the efficiency of real-time video synthesis. Ho…
