From Uncertainty to Determinism: Coarse-to-Fine Visual Floorplan Localization without Ray Matching
Shiyong Meng, Bolei Chen, Ping Zhong +4
Visual Floorplan Localization (FLoc) has emerged as a promising solution for indoor localization by matching egocentric images against minimalist structural maps. However, due to c…
FloAff-Kitchen: Bridging Navigation and Manipulation via Canonical and Progressive Floor Affordance Learning
Ping Zhong, Manling Teng, Tao Wu +3
Mobile manipulation requires robots to identify Floor Affordance (FloAff) that maximizes downstream manipulation success rather than merely ensuring navigation feasibility. FloAff…
Rethinking Generative Recommender Tokenizer: Recsys-Native Encoding and Semantic Quantization Beyond LLMs
Yu Liang, Zhongjin Zhang, Yuxuan Zhu +10
Semantic ID (SID)-based recommendation is a promising paradigm for scaling sequential recommender systems, but existing methods largely follow a semantic-centric pipeline: item emb…
Spatially Generalizable Mobile Manipulation via Adaptive Experience Selection and Dynamic Imagination
Ping Zhong, Liangbai Liu, Bolei Chen +4
Mobile Manipulation (MM) involves long-horizon decision-making over multi-stage compositions of heterogeneous skills, such as navigation and picking up objects. Despite recent prog…
