GNFormer: Gaussian Neural Field Transformer for Efficient Camera-based Occupancy Prediction
Guangcheng Chen, Li He, Hong Zhang
Camera-based occupancy prediction provides geometric and semantic scene understanding for robot perception and has been adopted in autonomous vehicle and UAV perception systems. Ga…
KnowledgeBerg: Evaluating Systematic Knowledge Coverage and Compositional Reasoning in Large Language Models
Xiao Zhang, Qianru Meng, Yongjian Chen +2
Many real-world questions appear deceptively simple yet implicitly demand two capabilities: (i) systematic coverage of a bounded knowledge universe and (ii) compositional set-based…
RankSteer: Can Pointwise LLM Rankers Be Calibrated at the Representation Level?
Yumeng Wang, Catherine Chen, Suzan Verberne
Large language models (LLMs) are strong zero-shot pointwise rankers, but lag behind pairwise and listwise methods. Beyond missing comparative signals, we identify a \textit{calibra…
Benchmark Leakage Trap: Can We Trust LLM-based Recommendation?
Mingqiao Zhang, Qiyao Peng, Yinghui Wang +2
The expanding integration of Large Language Models (LLMs) into recommender systems poses critical challenges to evaluation reliability. This paper identifies and investigates a pre…
