## [Introduction] KCM Framework: Addressing Knowledge Conflict Issues in Retrieval-Augmented Vision-Language Models

This article is the open-source implementation of an AAAI 2026 accepted paper, proposing the Knowledge Conflict Mitigation (KCM) framework. Targeting the inconsistency between retrieved knowledge and the model's internal knowledge in Retrieval-Augmented Vision-Language Models (Retrieval-Augmented VLMs), it improves the accuracy and reliability of model responses, reduces hallucinations, and enhances system credibility by explicitly detecting, resolving, and integrating conflicting knowledge.

## Research Background and Knowledge Conflict Issues

Retrieval-Augmented Generation (RAG) technology has been extended to vision-language models, forming Retrieval-Augmented VLMs, but there are knowledge conflict issues: manifested as factual (e.g., incorrect penguin habitat), timeliness (e.g., outdated presidential information), granularity (detailed vs. rough), and visual-text (contradiction between images and retrieved text) conflicts. Without handling these, it will lead to decreased response quality, invalid confidence, loss of user trust, and security risks.

## Core Ideas of the KCM Framework

KCM is based on three key insights: conflicts are normal, simple fusion is insufficient, and explicit modeling is needed. It follows three principles: conflict detection (calculating consistency, identifying types and severity), conflict resolution (retrieval priority/internal priority/fusion/uncertainty expression), and knowledge integration (conflict-aware attention, multi-source fusion, traceability).

## Detailed Technical Methods

1. Conflict Detection Module: Extract the model's internal response (pre-inference), obtain retrieved documents, calculate conflict scores (semantic similarity, uncertainty estimation, explicit comparison); 2. Conflict Resolution Strategies: Retrieval priority (increase retrieval weight), internal priority (supplementary retrieval), fusion (gated weighting), uncertainty expression (explicit explanation); 3. Integration Architecture: Conflict-aware attention (dynamically fuse internal and retrieved knowledge), multi-modal three-way fusion (vision + internal + retrieval), hierarchical processing (paragraph/sentence/document level).

## Training Strategy

Data Construction: Adversarial construction (generate wrong answers), timeliness construction (new and old knowledge bases), multi-source fusion (different knowledge sources); Training Objective: Total loss = generation loss + λ1 conflict detection loss + λ2 knowledge selection loss; Training Techniques: Curriculum learning (from simple to complex conflicts), contrastive learning (pull correct outputs closer, push wrong outputs away).

## Experimental Evaluation Results

Evaluation Metrics: Generation quality (accuracy, completeness, fluency), conflict handling ability (detection accuracy, strategy appropriateness, traceability accuracy), system-level metrics (hallucination rate, consistency, user satisfaction); Results: Significant accuracy improvement on benchmark datasets, more obvious improvement on conflict subsets, reduced hallucination rate; Ablation experiments verify the contribution of each component, and the complete framework has the best effect; Case analysis shows the advantages in handling timeliness, visual-text conflicts, and uncertainty expression.

## Application Scenarios, Limitations, and Future Work

Application Scenarios: Real-time knowledge Q&A (news images, product recognition, landmarks), professional fields (medical imaging, legal documents, scientific literature), multi-modal dialogue systems; Limitations: High computational cost, generalization ability needs improvement, evaluation challenges; Future Directions: Efficient conflict detection, adaptive strategy learning, multi-turn dialogue processing, extension to pure text RAG, multi-modal support, real-time system optimization.

## Conclusion

KCM brings a new perspective to Retrieval-Augmented VLMs, emphasizing the importance of explicitly handling knowledge conflicts to improve system accuracy and reliability. It is of great significance to AI safety and practicality, provides a technical route for building multi-modal RAG systems, and helps to create more robust vision-language understanding systems.
