DarkFarseer: Robust Spatio-Temporal Kriging Under Graph Sparsity and Noise

AAAI 2026technical

The rapid expansion of the Internet of Things (IoT) has created a growing demand for large-scale sensor deployment. However, the high cost of physical sensors limits the scalability and coverage of sensor networks, making fine-grained sensing difficult. Inductive Spatio-Temporal Kriging (ISK) addres

A Streamlined Span-based Factorization Method for Few Shot Named Entity Recognition

COLING 2024main

Few-shot named entity recognition (NER) is a challenging task that aims to recognize new named entities with only a limited amount of labeled examples. In this paper, we introduce SSF, which is a streamlined span-based factorization method that addresses the problem of few-shot NER. Our approach for…
