Adversarial Decoys: Misdirecting Attention-Based Defenses in ViT

Researchers propose adversarial decoys, independently optimized image patches that redirect attention away from adversarial regions, bypassing attention-based defenses in Vision Transformers. The approach decouples misclassification and defense evasion, is attack-agnostic, and preserves attack effectiveness. Experiments on ImageNet reveal a fundamental limitation of using attention magnitude as an indicator of adversarial relevance.

Hallucination Self-Play: Bootstrapping Reinforced Detector via Evolved Generator

Identifying faithfulness hallucinations in LLM-generated outputs remains challenging due to the scarcity of high-quality annotated data. This paper introduces Hallucination Self-Play (HSP), a framework where a detector and generator bootstrap each other. The detector is fine-tuned on human labels, then used as a reward model to train the generator via RLAIF to produce harder-to-detect hallucinations. The evolved generator's outputs further optimize the detector via rule-based RL. Experiments on RAGTruth and two model families show a small LLM can match or outperform advanced LLMs without external supervision.

From Solvers to Research: Large Language Model-Driven Formal Mathematics at the Research Frontier

This position paper reviews recent advances in AI for Mathematics (AI4Math), particularly LLM-driven theorem provers for formal proof generation. It argues that current systems are limited to well-defined problems and cannot handle open-ended frontier research like discovering new theorems. The authors advocate shifting from problem solvers to research agents capable of rigorous formal reasoning, and identify key limitations across datasets, relational structure, exploration, tools, and human-AI collaboration, outlining a roadmap for the future of AI4Math.

Who Gets Missed in the Tail? Thresholded Subgroup Underdiagnosis in Long-Tailed Chest X-ray Classification

In chest X-ray classification, acceptable ranking performance can still miss rare-positive patients below threshold, especially within subgroups. Using a diagnostic ladder, group-tail weighting followed by tail-aware thresholding reduces tail FNR from 0.665 to 0.269, but residual missed rates remain high. Fairness depends on finding, subgroup, and threshold jointly.
