How does dynamic iterative retrieval with varying passage counts per hop affect the efficiency-accuracy trade-

Abstract

Abstract: Multi-Hop Question Answering (MHQA) tasks permeate real-world applications, posing challenges in orchestrating multi-step reasoning across diverse knowledge domains. While existing approaches have been improved with iterative retrieval, they still struggle to identify and organize dynamic knowledge. To address this, we propose DualRAG, a synergistic dual-process framework that seamlessly integrates reasoning and retrieval. DualRAG operates through two tightly coupled processes: Reasoning-augmented Querying (RaQ) and progressive Knowledge Aggregation (pKA). They work in concert: as RaQ navigate

Research Question

How does dynamic iterative retrieval with varying passage counts per hop affect the efficiency-accuracy trade-off on HotPotQA compared to single-retrieval methods?
