Reinforcement Learning for RAG
GenR1-Searcher: Curriculum Reinforcement Learning for Dynamic Retrieval and Document Generation
GenR1-Searcher introduces a novel curriculum-based reinforcement learning framework that empowers small language models to dynamically decide between retrieval and document generation for multi-hop reasoning. Through a three-stage progressive training strategy, the model learns tool invocation, retrieval mastery, and adaptive tool selection. This approach significantly outperforms existing RAG methods by leveraging the complementary strengths of both information retrieval for reliability and LLM-generated content for query-specific relevance, leading to substantial improvements across various QA benchmarks.
Executive Impact & Business Value
GenR1-Searcher revolutionizes knowledge-intensive task automation by delivering more accurate, efficient, and adaptable AI responses. This translates directly into improved operational efficiency and enhanced decision-making for enterprises.

This paper leverages advanced Reinforcement Learning (RL) techniques, specifically a curriculum-based approach, to train language models. It demonstrates how RL can optimize tool selection policies for complex multi-hop reasoning tasks, leading to adaptive and efficient information acquisition.
GenR1-Searcher's Three-Stage Progressive Learning
Our novel curriculum-based reinforcement learning framework trains small language models to intelligently decide between retrieval and document generation during multi-hop reasoning. This progressive strategy ensures stable training and adaptive tool coordination.
Impact of Curriculum Learning and Dual Tools
Ablation studies confirm the necessity of all GenR1-Searcher components. Removing curriculum learning causes a significant performance decline, highlighting its importance.
0 Relative EM Decline from Skipping CurriculumThe core contribution of this work lies in enhancing Retrieval-Augmented Generation (RAG) paradigms. By dynamically integrating both external retrieval and LLM-based document generation, GenR1-Searcher addresses the limitations of traditional RAG methods, such as noisy retrievals or factual inaccuracies from generation-only approaches. This dual-tool coordination significantly improves answer quality and reasoning capabilities for open-domain QA.

Adaptive Tool Selection in Multi-hop QA
A case study demonstrating GenR1-Searcher's ability to dynamically switch between retrieval and generation tools based on query needs and search results, effectively handling incomplete information.
User Query: In what city was the film "Yes, Giorgio" set or filmed?
Phase 1: Initial Search & Analysis
The model first attempts to retrieve information based on the initial query. The retrieved documents are relevant to the film but lack the specific city location, indicating an information gap.
<think> I need to find information about where the film "Yes, Giorgio" was set or filmed. Let me search for the filming locations of this movie. </think>
<search> "Yes Giorgio" film location city </search>
<documents> (1) Yes, Giorgio - Yes, Giorgio is a 1982 musical-comedy film starring Luciano Pavarotti... [no location info]
(2) San Giorgio di Piano - ...a town in northern Italy [unrelated] (3) Giorgio Capitani - ...Italian film director [unrelated] </documents>
Phase 2: Adaptive Generation
Recognizing the search results are incomplete, the model dynamically switches to the generation tool, formulating a refined query to obtain the missing specific city information.
<think> The search results don't specify which city it was set or filmed in. I need more specific information about the actual filming locations. Let me generate more detailed information. </think>
<generation> "Yes Giorgio" 1982 film Italy city location filmed set </generation>
<documents> "Yes, Giorgio" is a 1982 romantic comedy film that was primarily set and filmed in various Italian locations. The main city featured in the film is Rome, Italy, where many of the key scenes take place... </documents>
Phase 3: Final Answer Extraction
From the newly generated, query-tailored document, the model successfully extracts the precise answer.
<answer> Rome, Italy </answer>
