Separate First, Fuse Later: Mitigating Cross-Modal Interference in Audio-Visual LLMs Reasoning with Modality-Specific Chain-of-Thought

Researchers propose SFFL, a framework that mitigates cross-modal interference in audio-visual language models by enforcing separate reasoning chains for each modality before fusion. The approach uses modality-preference labels and reinforcement learning to reduce hallucinations and achieves 5-11% performance improvements on benchmarks.

Probing Cross-modal Information Hubs in Audio-Visual LLMs

Researchers have analyzed how audio-visual large language models (AVLLMs) process cross-modal information, discovering that integrated audio-visual data concentrates in specialized 'sink tokens' rather than distributing uniformly. This finding enables a training-free method to reduce hallucinations by leveraging these cross-modal information hubs.

From Surface Learning to Deep Understanding: A Grounded AI Tutoring System for Moodle

Researchers have developed an AI Teaching & Learning Assistant, a Moodle plugin using Retrieval-Augmented Generation (RAG) to provide students with Socratic tutoring while enabling educators to supervise content generation. The system grounds LLM responses in teacher-provided materials to minimize hallucinations and misinformation, achieving high faithfulness scores (0.97) and strong user satisfaction (4.00/5.00 rating).

Theory Under Construction: Orchestrating Language Models for Research Software Where the Specification Evolves

Researchers propose Comet-H, an AI system that orchestrates language models to generate research software by keeping mathematical theory, code, benchmarks, and documentation synchronized. The framework addresses hallucination and desynchronization failures in LLM-driven development, demonstrating effectiveness through a portfolio of 46 research repositories, with a static-analysis tool reaching F1=0.768 performance.

Mechanisms of Prompt-Induced Hallucination in Vision-Language Models

Researchers identify specific attention heads in vision-language models that cause prompt-induced hallucinations, where models favor textual instructions over visual evidence. By ablating these identified heads, they reduce hallucinations by 40% without retraining, revealing model-specific mechanisms underlying this failure mode.

Noise-Aware In-Context Learning for Hallucination Mitigation in ALLMs

Researchers propose Noise-Aware In-Context Learning (NAICL), a plug-and-play method to reduce hallucinations in auditory large language models without expensive fine-tuning. The approach uses a noise prior library to guide models toward more conservative outputs, achieving a 37% reduction in hallucination rates while establishing a new benchmark for evaluating audio understanding systems.

Constraining Sequential Model Editing with Editing Anchor Compression

Researchers propose Editing Anchor Compression (EAC), a framework that addresses degradation of large language models' general abilities during sequential knowledge editing. By constraining parameter matrix deviations through selective anchor compression, EAC preserves over 70% of model performance while maintaining edited knowledge, advancing the practical viability of model editing as an alternative to expensive retraining.

Focus Matters: Phase-Aware Suppression for Hallucination in Vision-Language Models

Researchers developed a new method to reduce hallucinations in Large Vision-Language Models (LVLMs) by identifying a three-phase attention structure in vision processing and selectively suppressing low-attention tokens during the focus phase. The training-free approach significantly reduces object hallucinations while maintaining caption quality with minimal inference latency impact.

Thinking in Uncertainty: Mitigating Hallucinations in MLRMs with Latent Entropy-Aware Decoding

Researchers propose Latent Entropy-Aware Decoding (LEAD), a new method to reduce hallucinations in multimodal large reasoning models by switching between continuous and discrete token embeddings based on entropy states. The technique addresses issues where transition words correlate with high-entropy states that lead to unreliable outputs in visual question answering tasks.
