Survey of Knowledge Conflicts in Large Language Models: Pathways to Enhanced Accuracy and Reliability

Large language models (LLMs) have taken center stage in artificial intelligence, fueling advancements in lots of applications, from enhancing conversational AI to powering complex analytical tasks. Their crux of functionality lies of their ability to sift through and apply an unlimited repository of encoded knowledge acquired through exhaustive training on wide-ranging datasets. This strength also poses a novel set of challenges, chiefly the problem of data conflicts.

Central to the knowledge conflict dilemma is the clash between LLMs’ static, pre-learned information and the always evolving, real-time data they encounter post-deployment. This will not be merely an educational concern but a practical one, affecting the models’ reliability and effectiveness. For instance, when interpreting latest user inputs or current events, LLMs might reconcile this fresh information with their existing, possibly outdated, knowledge base.

Researchers from  Tsinghua University, Westlake University, and The Chinese University of Hong Kong have surveyed the research done on this issue and presented how the research community is actively exploring avenues to mitigate the impact of data conflicts on LLM performance. Earlier approaches have centered around periodically updating the models with latest data, employing retrieval-augmented strategies to access up-to-date information, and continuous learning mechanisms to integrate fresh insights adaptively. While invaluable, these strategies often must be revised to totally bridge the gap between the static nature of LLMs’ intrinsic knowledge and the dynamic landscape of external data sources.

The survey shows how the research community has introduced novel methodologies to boost LLMs’ capability to administer and resolve knowledge conflicts. This ongoing effort, driven by a collective determination, involves developing more sophisticated techniques for dynamically updating models’ knowledge bases and refining their ability to differentiate between various sources of knowledge. The involvement of leading tech corporations on this research underscores the critical importance of creating LLMs more adaptable and trustworthy in handling real-world data.

Through a scientific categorization of conflict types and the appliance of targeted resolution strategies, significant strides have been made in curtailing the spread of misinformation and boosting the general accuracy of LLM-generated responses, providing reassurance concerning the positive direction of the research. These advances reflect a deeper understanding of the underlying causes of data conflicts. This includes recognizing the distinct nature of disputes arising from real-time information versus pre-existing data and implementing solutions tailored to those specific challenges.

In conclusion, exploring knowledge conflicts in LLMs underscores a pivotal aspect of artificial intelligence research: the perpetual balancing act between leveraging vast amounts of stored knowledge and adapting to the ever-changing real-world information. Researchers have also illuminated the implications of data conflicts beyond mere factual inaccuracies. Recent studies have focused on LLMs’ ability to take care of consistency of their responses, particularly when faced with semantically similar queries that may trigger conflicting internal data representations.
