Exploring AGI Hallucination: A Comprehensive Survey of Challenges and Mitigation Strategies

A recent comprehensive survey titled "A Survey of AGI Hallucination" by Feng Wang from Soochow University sheds light on the challenges and current research surrounding hallucinations in Artificial General Intelligence (AGI) models. As AGI continues to advance, addressing the issue of hallucinations has become a critical focus for researchers in the field.

The survey categorizes AGI hallucinations into three main types: conflict in intrinsic knowledge of models, factual conflict in information forgetting and updating, and conflict in multimodal fusion. These hallucinations manifest in various ways across different modalities, such as language, vision, video, audio, and 3D or agent-based systems.

The authors explore the emergence of AGI hallucinations, attributing them to factors like training data distribution, timeliness of information, and ambiguity in different modalities. They emphasize the importance of high-quality data and appropriate training techniques in mitigating hallucinations.

Current mitigation strategies are discussed in three stages: data preparation, model training, and model inference and post-processing. Techniques like RLHF (Reinforcement Learning from Human Feedback) and knowledge-based approaches are highlighted as effective methods for reducing hallucinations.

Evaluating AGI hallucinations is crucial for understanding and addressing the issue. The survey covers various evaluation methodologies, including rule-based, large model-based, and human-based approaches. Benchmarks specific to different modalities are also discussed.

Interestingly, the survey notes that not all hallucinations are detrimental. In some cases, they can stimulate a model's creativity. Finding the right balance between hallucination and creative output remains a significant challenge.

Looking to the future, the authors emphasize the need for robust datasets in areas like audio, 3D modeling, and agent-based systems. They also highlight the importance of investigating methods to enhance knowledge updating in models while retaining foundational information.

As AGI continues to evolve, understanding and mitigating hallucinations will be essential for developing reliable and safe AI systems. This comprehensive survey provides valuable insights and paves the way for future research in this critical area.
