  • Beyond Sparse Supervision: Diffusion-Guided Learning for Few-Shot Graph Fraud Detection

    Beyond Sparse Supervision: Diffusion-Guided Learning for Few-Shot Graph Fraud Detection
    2026/06/30
    Financial fraud detection in transaction networks faces a fundamental challenge: fraudulent activity is rare, well-disguised, and often underrepresented in labeled data. Standard graph neural networks tend to smooth out the very irregularities that signal fraud. ADC-GNN tackles this with three complementary mechanisms: diffusion-guided feature augmentation that stabilizes node representations against noise, contrastive learning across perturbed views, and a spectral attention module that adaptively amplifies fraud-relevant frequency signals across multiple graph hops. Evaluated on public benchmarks and a real telecom transaction dataset, it consistently outperforms baselines under low-label conditions. Applications include credit card fraud detection, anti-money laundering systems, telecommunications billing abuse detection, and social network spam identification.

  • Toward Robust In-Context Segmentation via Concept Guidance

    Toward Robust In-Context Segmentation via Concept Guidance
    2026/06/30
    In-context segmentation asks a model to identify target regions in new images using only a handful of labeled reference examples — no retraining required. Current approaches work by matching low-level visual features between references and queries, making them brittle when references vary in viewpoint, lighting, or appearance. CG-ICS instead extracts high-level semantic concepts from references using a multimodal language model, then uses these concepts alongside a spatial grounding route to guide a frozen SAM3 segmentation backbone. It achieves state-of-the-art accuracy and substantially reduced variance across diverse reference choices. Applications span medical image annotation, few-shot industrial inspection, and rapid domain adaptation in computer vision pipelines with limited labeled data.

  • Robust Harmful Features Under Jailbreak Attacks: Mechanistic Evidence from Attention Head Specialization in Large Language Models

    Robust Harmful Features Under Jailbreak Attacks: Mechanistic Evidence from Attention Head Specialization in Large Language Models
    2026/06/30
    Jailbreak attacks — prompts engineered to make safety-aligned LLMs produce harmful outputs — are a persistent concern, but exactly how they work mechanistically has remained murky. This paper provides evidence that successful attacks don't erase safety representations; they selectively suppress specific "Adversarially Compromised Heads" in early attention layers while leaving "Safety-Aligned Heads" in mid-layers largely intact. This residual safety signal is detectable without any additional training, and reading it yields competitive jailbreak detection performance with strong robustness. These findings have direct implications for LLM safety auditing, interpretability-based defenses, red-teaming methodologies, and the design of future architectures with more resilient safety mechanisms.
