Analysis

The user's experience highlights a potential flaw in Gemini's output generation, where the model persistently uses analogies despite explicit instructions to avoid them. This suggests a weakness in the model's ability to adhere to user-defined constraints and raises questions about the effectiveness of customization features. The issue could stem from a prioritization of certain training data or a fundamental limitation in the model's architecture.

Key Takeaways

•Gemini 3.0 Pro exhibits a tendency to use analogies even when instructed not to.
•Users are experiencing difficulty in customizing Gemini's output to avoid unwanted content types.
•The issue is present across different Gemini interfaces, including AI Studio and AG.

ArXiv NLP

Analysis

This paper introduces M$^3$KG-RAG, a novel approach to Retrieval-Augmented Generation (RAG) that leverages multi-hop multimodal knowledge graphs (MMKGs) to enhance the reasoning and grounding capabilities of multimodal large language models (MLLMs). The key innovations include a multi-agent pipeline for constructing multi-hop MMKGs and a GRASP (Grounded Retrieval And Selective Pruning) mechanism for precise entity grounding and redundant context pruning. The paper addresses limitations in existing multimodal RAG systems, particularly in modality coverage, multi-hop connectivity, and the filtering of irrelevant knowledge. The experimental results demonstrate significant improvements in MLLMs' performance across various multimodal benchmarks, suggesting the effectiveness of the proposed approach in enhancing multimodal reasoning and grounding.

Key Takeaways

•Introduces M$^3$KG-RAG for enhanced multimodal RAG.
•Utilizes multi-hop MMKGs to improve reasoning depth.
•Employs GRASP for precise entity grounding and context pruning.
