Hallucination in AI

Hallucination is a significant concern in the development of large language models (LLMs) and other AI systems. It refers to the tendency of these models to generate outputs that are factually incorrect, nonsensical, or not grounded in reality. Researchers are actively exploring various techniques to mitigate hallucinations and improve the reliability of AI systems. Below are some of the latest papers addressing this issue:

1. Tell Model Where to Look: Mitigating Hallucinations in MLLMs by Vision-Guided Attention

Published on November 25, 2025, this paper proposes a novel approach to mitigate hallucinations in Multimodal Large Language Models (MLLMs) by guiding their attention using visual cues. The study, currently under review, suggests that by explicitly directing the model's focus to relevant visual information, it's possible to reduce the generation of hallucinated content. This is particularly important in applications where AI systems need to integrate visual and textual information accurately. The core idea revolves around equipping models with a mechanism to prioritize and interpret visual data effectively, thus anchoring the textual output in verifiable visual elements. This vision-guided attention mechanism could significantly enhance the reliability of MLLMs in tasks such as image captioning, visual question answering, and other multimodal applications. The paper likely details the architecture of the proposed model, the training methodology, and experimental results demonstrating the effectiveness of the approach in reducing hallucinations compared to existing methods. Furthermore, it may explore the limitations of the technique and suggest avenues for future research, such as incorporating different attention mechanisms or exploring the use of diverse visual cues. The implications of this research are far-reaching, as it addresses a fundamental challenge in the development of robust and trustworthy AI systems.

2. Alternating Perception-Reasoning for Hallucination-Resistant Video Understanding

Safety in AI

Ensuring the safety of AI systems is paramount as they become increasingly integrated into various aspects of our lives. This includes developing methods to prevent unintended consequences, mitigate risks, and align AI behavior with human values. The following papers explore different facets of AI safety:

1. Predictive Safety Shield for Dyna-Q Reinforcement Learning

Published on November 26, 2025, this paper introduces a Predictive Safety Shield for Dyna-Q Reinforcement Learning. Reinforcement learning (RL) algorithms, while powerful, can sometimes lead to unsafe or undesirable behavior during the learning process. The Predictive Safety Shield aims to address this by proactively identifying and preventing potentially harmful actions. Dyna-Q is a model-based RL algorithm, which means it learns a model of the environment to plan its actions. The Predictive Safety Shield likely leverages this model to predict the consequences of different actions and intervene when necessary to ensure safety. This could involve modifying the reward function, constraining the action space, or implementing other mechanisms to guide the agent towards safe exploration and learning. The paper likely details the specific algorithms and techniques used to implement the Predictive Safety Shield, as well as experimental results demonstrating its effectiveness in preventing unsafe behavior in various RL environments. This research contributes to the development of more robust and reliable RL systems that can be deployed in real-world applications where safety is critical.

2. Self-Guided Defense: Adaptive Safety Alignment for Reasoning Models via Synthesized Guidelines

This paper, also published on November 26, 2025, presents a Self-Guided Defense mechanism for adaptive safety alignment in reasoning models. Reasoning models, which are designed to perform complex reasoning tasks, can sometimes exhibit unintended behavior or generate outputs that are misaligned with human values. The Self-Guided Defense approach aims to address this by equipping the model with the ability to generate and follow its own safety guidelines. This likely involves training the model to synthesize guidelines that promote safe and ethical behavior, and then using these guidelines to guide its reasoning process. The adaptive nature of the approach suggests that the model can adjust its safety guidelines based on its experiences and the specific context of the task. This paper likely details the architecture of the Self-Guided Defense mechanism, the training methodology, and experimental results demonstrating its effectiveness in improving the safety and alignment of reasoning models. This research contributes to the development of AI systems that are not only capable of complex reasoning but also adhere to ethical principles and human values.

Published on November 26, 2025, this paper explores a method for breaking the safety-capability tradeoff in Large Language Models (LLMs) using Reinforcement Learning with Verifiable Rewards. The paper is also slated to be presented at the AAAI-26 Workshop on Post-AI Formal Methods. The safety-capability tradeoff refers to the challenge of simultaneously maximizing the performance and ensuring the safety of AI systems. Often, efforts to improve safety can lead to a decrease in capabilities, and vice versa. This research proposes a novel approach that uses Reinforcement Learning with Verifiable Rewards to maintain safety guardrails in LLMs without sacrificing their capabilities. This likely involves designing reward functions that explicitly incentivize safe behavior, as well as incorporating formal methods to verify that the model adheres to predefined safety constraints. The paper likely details the specific techniques used to define verifiable rewards and integrate them into the RL training process. Experimental results would likely demonstrate the effectiveness of the approach in maintaining safety while preserving the capabilities of LLMs. This research is significant because it addresses a fundamental challenge in the development of responsible AI systems, paving the way for LLMs that are both powerful and safe.

4. GuardTrace-VL: Detecting Unsafe Multimodel Reasoning via Iterative Safety Supervision

This paper, published on November 26, 2025, introduces GuardTrace-VL, a method for detecting unsafe multimodal reasoning through iterative safety supervision. Multimodal reasoning involves integrating information from different modalities, such as text, images, and audio. While powerful, multimodal reasoning systems can also be susceptible to generating unsafe or undesirable outputs. GuardTrace-VL aims to address this by iteratively supervising the reasoning process and detecting potential safety violations. This likely involves monitoring the model's internal states, attention patterns, and generated outputs to identify instances where the model is deviating from safe reasoning pathways. The iterative nature of the approach suggests that it involves a feedback loop, where the model's behavior is continuously monitored and corrected to ensure safety. The paper likely details the specific techniques used to implement GuardTrace-VL, as well as experimental results demonstrating its effectiveness in detecting unsafe multimodal reasoning. This research contributes to the development of more robust and reliable multimodal AI systems that can be deployed in real-world applications where safety is paramount.
