Core Viewpoint - The article discusses the "seesaw" dilemma faced by deep thinking large models, where frequent calls to search tools improve accuracy but lead to increased computational costs and inefficiency. The proposed LightSearcher framework aims to address this issue by introducing an efficient RL optimization technique based on experiential memory, allowing for autonomous optimization of tool usage without relying on additional data [1][9]. Group 1 - The LightSearcher framework maintains accuracy comparable to the SOTA baseline ReSearch while significantly reducing search tool calls by 39.6%, inference time by 48.6%, and token consumption by 21.2% [2]. - The DeepSeek-R1 model can handle complex reasoning tasks, with DeepSearch serving as its core searcher, enhancing reasoning depth and factual reliability by accessing the latest domain-specific knowledge [4]. - High-frequency calls to external search tools can improve real-time information accuracy but lead to significant reasoning delays, with wait times reaching up to several minutes [5][7]. Group 2 - The article identifies existing methods' significant flaws, including reliance on manual labeling, excessive tool calls for simple queries, and a lack of balance between accuracy and efficiency [10][11][12]. - The LightSearcher framework introduces three key components: Contrastive Experiential Reasoning for building a dynamic memory library, Adaptive Reward Shaping to balance accuracy and efficiency, and an RL training mechanism to guide the model in generating efficient trajectories [15][18]. - Experimental results show that LightSearcher achieves top-tier accuracy, with an F1 score of 54.1, and demonstrates strong generalization capabilities across different query difficulties [22][23]. Group 3 - The removal of the experiential component led to a 7.2% drop in F1 score, highlighting its critical role in the framework [24]. - The framework successfully addresses key pain points in existing DeepSearch methods, providing a new pathway for building efficient and reliable deep reasoning systems [26][27]. - LightSearcher is expected to expand beyond multi-hop QA to areas such as code synthesis and strategic planning in the future [26].

Core Insights - The article discusses the challenges faced by existing RL-driven deep thinking models, particularly the trade-off between accuracy and efficiency, where frequent calls to external search tools improve accuracy but significantly increase response time [2][6]. - The introduction of the LightSearcher framework by the Beijing University of Posts and Telecommunications AI team addresses these challenges by utilizing experiential memory and adaptive reward shaping to enhance efficiency while maintaining accuracy [3][9]. Summary by Sections Introduction - The need for deep thinking models to strategically control the use of search tools is emphasized, highlighting existing methods' shortcomings in balancing accuracy and efficiency [6]. LightSearcher Framework - LightSearcher is designed to optimize the use of search tools through experiential memory, which transforms implicit reasoning paths into explicit guiding experiences, and includes adaptive reward mechanisms [9][11]. Experimental Results - Comprehensive evaluations on multiple multi-hop QA benchmark datasets demonstrate that LightSearcher maintains competitive accuracy while significantly reducing search tool calls by 39.6%, reasoning time by 48.6%, and token consumption by 21.2% [18]. - The framework's core components include: - Contrastive Experiential Reasoning, which builds a dynamic memory library from high and low-quality reasoning paths [14]. - Adaptive Reward Shaping, which minimizes redundant tool calls and balances accuracy and efficiency [14]. - Experience-based RL training, which integrates accumulated experiences into prompt templates to guide efficient reasoning [14]. Conclusion - LightSearcher provides a new pathway for constructing efficient and reliable deep reasoning systems, with potential applications extending beyond multi-hop QA to areas like code synthesis and strategic planning [18][20].
