Tree-Based Retrieval Stability in Multi-Hop Question Answering with Llama-3-8B-128K

Abstract

Abstract: This report synthesises findings from 11 peer-reviewed papers addressing the following research question: What is the impact of varying the number of retrieval hops (e.g., 2-hop vs. 3-hop) on the F1 score stability of the Tree of Reviews framework compared to chain-based retrieval in Llama-3-8B-128K when. Multi-hop question answering is a knowledge-intensive complex problem. Large Language Models (LLMs) use their Chain of Thoughts (CoT) capability to reason complex problems step by step, and retrieval-augmentation can effectively alleviate factual errors caused by outdated and. 9 claims were extracted from source literature; 3 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 5.8/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research Question

What is the impact of varying the number of retrieval hops (e.g., 2-hop vs. 3-hop) on the F1 score stability of the Tree of Reviews framework compared to chain-based retrieval in Llama-3-8B-128K when evaluated on the MuSiQue benchmark?
