What papers say
Verbatim critique sentences, each from a paper that cites IRCoT as a baseline.
“While these approaches improve evidence coverage, multi-round retrieval introduces unavoidable computational overhead, limiting their use in latency-sensitive applications.”
— SentGraph: Hierarchical Sentence Graph for Multi-hop Retrieval-Augmented Question Answering“Since the LLMs are prone to hallucinate, the generated CoT sentences may be inaccurate~luo2023reasoning,nguyen2024direct and lead to suboptimal performance.”
— TRACE the Evidence: Constructing Knowledge-Grounded Reasoning Chains for Retrieval-Augmented Generation“However, these models all rely on LLM-generated thoughts, making them prone to hallucination.”
— KiRAG: Knowledge-Driven Iterative Retriever for Enhancing Retrieval-Augmented Generation“While suitable for multi-step reasoning tasks, its rigid structure may limit performance in scenarios requiring parallel information aggregation.”
