Beyond Local Patterns: Multiscale Inconsistency Learning for Graph Anomaly Detection

AAAI 2026technical

Graph anomaly detection is emerging as a critical technology for addressing increasingly complex and dynamic risk environments. Although unsupervised graph anomaly detection has advanced under the graph representation learning, directly applying these paradigms remains fundamentally misaligned with

Solving Instance Detection from an Open-World Perspective

CVPR 2025poster

Instance detection (InsDet) aims to localize specific object instances within a novel scene imagery based on given visual references. Technically, it requires proposal detection to identify all possible object instances, followed by instance-level matching to pinpoint the ones of interest. Its open-…

A High-Resolution Dataset for Instance Detection with Multi-View Object Capture

NeurIPS 2023poster

Instance detection (InsDet) is a long-lasting problem in robotics and computer vision, aiming to detect object instances (predefined by some visual examples) in a cluttered scene. Despite its practical significance, its advancement is overshadowed by Object Detection, which aims to detect objects be…
