Detect by Yourself: Self-Designing Agentic Workflows for Few-Shot Graph Anomaly Detection

arXiv:2605.27470v1 Announce Type: new Abstract: Graph anomaly detection aims to identify anomaly nodes in attributed graphs and plays an important role in real-world applications. However, existing graph anomaly detection methods still face two key challenges: 1) fixed pipelines, which restrict their adaptability across different graph tasks under limited supervision; 2) weak evidence, which prevents them from explicitly incorporating contextual and structural anomaly signals into the detection process. In this paper, we propose a novel framework, self-designing agentic workflows for few-shot

Why this matters
Why now

The proliferation of complex graph data in various domains and the limitations of fixed AI models are driving demand for more adaptive and autonomous detection systems.

Why it’s important

This development points towards a significant evolution in AI's ability to self-configure and adapt to novel challenges with limited data, impacting the efficiency and applicability of AI in critical sectors.

What changes

AI systems are moving from predefined algorithms to agentic, self-designing workflows, enabling greater adaptability and robustness especially in anomaly detection.
