Core Viewpoint - The article discusses RefineX, a new framework developed by the Institute of Computing Technology, Chinese Academy of Sciences, and Alibaba Qwen, aimed at efficiently refining large-scale pre-training data through programmatic editing tasks, addressing noise pollution that affects data quality [1][2]. Group 1: Advantages of RefineX - RefineX distills high-quality end-to-end optimization results into a simplified deletion program based on editing operations, enhancing the efficiency of data refinement [2][11]. - The high-precision distillation process enables the training of an efficient and reliable refine model that systematically optimizes each instance in the corpus [3][12]. - While refining data efficiently, RefineX reliably preserves the diversity and naturalness of the original text [4][19]. Group 2: Performance Metrics - Training a 750M model with 20 billion tokens refined by RefineX achieved an average score of 44.7 across ten tasks, representing a 7.2% improvement over the original data [5][25]. - The model using 10 billion refined tokens outperformed those trained on 20 billion traditional filtered data, indicating that RefineX effectively reduces training token costs while allowing for more diverse text consideration [25]. Group 3: Data Quality Improvement - RefineX demonstrated a 42.2% improvement rate in the quality of low-quality content while maintaining a "zero new vocabulary" policy, thus eliminating any risk of hallucination [29]. - The end-to-end approach, while showing higher improvement rates, introduced external vocabulary at a rate of 15 new words per thousand tokens, posing semantic alteration risks [29]. Group 4: Methodology and Process - RefineX employs a two-stage process for data distillation: first, it executes end-to-end refinement, then compares the refined text with the original to generate more reliable supervision programs [11][16]. - The framework limits program functions to deletion operations only, ensuring that the original text is protected from excessive modifications [19][20]. Group 5: Comparative Analysis - RefineX consistently achieved the highest average scores across various tasks, outperforming both original and previously filtered datasets [26]. - The results indicate that regardless of whether the original data or previously filtered datasets were improved, models trained with RefineX consistently achieved superior performance [26].

Core Viewpoint - The article discusses the Metis-RISE framework developed by researchers from Meituan, which combines Reinforcement Learning (RL) and Supervised Fine-Tuning (SFT) in a novel way to enhance the reasoning capabilities of Multimodal Large Language Models (MLLMs) [1][2]. Summary by Sections Introduction of Metis-RISE Framework - The Metis-RISE framework integrates RL and SFT in a non-traditional sequence to effectively improve MLLMs' reasoning abilities [2][3]. Training Methodology - The training process consists of two phases: - Phase 1 focuses on RL incentives, allowing the model to explore freely and activate its potential [6]. - Phase 2 employs SFT to address specific weaknesses identified during the RL phase [7][8]. Performance Results - The models developed, Metis-RISE-7B and Metis-RISE-72B, achieved impressive scores on the OpenCompass multimodal reasoning leaderboard, with the 72B model ranking fourth overall [3][14]. - Metis-RISE-72B achieved an average score of 56.6, outperforming several proprietary models and demonstrating its competitive edge [13][14]. Comparative Analysis - The performance of Metis-RISE models was compared against proprietary models and open-source models, showing superior results, particularly in the >10B parameter category [11][12][13]. Ablation Studies - Detailed ablation studies indicated that the RL phase significantly improved the model's performance, with average scores increasing from 39.2 to 44.0 after applying RL [15][16]. Qualitative Analysis - Observations during the RL phase revealed a consistent increase in accuracy rewards and response lengths, indicating improved reasoning clarity as training progressed [17]. Future Directions - The team plans to continue exploring iterative applications of RL and SFT to further enhance reasoning capabilities and develop model-based validators for more complex reasoning scenarios [18].

Core Viewpoint - The research team from Zhejiang University and vivo AI Lab has made significant progress in developing a cognitive-driven navigation framework called CogDDN, which enables robots to understand human intentions and navigate complex environments autonomously [2][5][33]. Research Motivation - As mobile robots become more integrated into daily life, there is a need for them to not only execute commands but also understand human needs, such as seeking food when a person feels hungry [5]. - Traditional demand-driven navigation methods rely heavily on extensive data training and struggle in unfamiliar environments or vague instructions, prompting the exploration of more generalizable navigation methods [6]. Framework Overview - The CogDDN framework is based on the dual-process theory from psychology, combining heuristic (System 1) and analytical (System 2) decision-making processes to simulate human-like reasoning in navigation tasks [8][20]. - The framework consists of three main components: a 3D robot perception module, a demand matching module, and a dual-process decision-making module [13]. 3D Robot Perception Module - The team utilized the state-of-the-art single-view 3D detection method, UniMODE, to enhance the robot's three-dimensional perception capabilities in indoor navigation [15]. Demand Matching Module - The demand matching module aligns objects with human needs based on shared characteristics, employing supervised fine-tuning techniques to improve the accuracy of recommendations in complex scenarios [16]. Dual-Process Decision Making - The heuristic process allows for quick, intuitive decision-making, while the analytical process focuses on error reflection and strategy optimization [9][23]. - The heuristic process includes two sub-modules: Explore, which generates exploratory actions to scan the environment, and Exploit, which focuses on precise actions to achieve navigation goals [19]. Experimental Results - In closed-loop navigation experiments using the AI2-THOR simulator, CogDDN outperformed existing state-of-the-art methods, achieving a navigation success rate (NSR) of 38.3% and a success rate for weighted path length (SPL) of 17.2% [26][27]. - The framework demonstrated superior adaptability and efficiency in unseen scenes compared to methods that rely solely on forward-facing camera inputs [28]. Continuous Learning and Adaptation - The analysis process in CogDDN allows for iterative learning, where the system reflects on obstacles encountered during navigation and integrates this knowledge into its decision-making framework [24][31]. - The reflection mechanism significantly enhances the system's performance in future navigation tasks, showcasing its robust learning capabilities [32]. Conclusion - CogDDN represents a significant advancement in cognitive-driven navigation systems, enabling robots to efficiently adapt and optimize their strategies in complex environments [33][34]. - The dual-process capability of CogDDN lays a solid foundation for the development of intelligent robotic technologies in demand-driven navigation tasks [35].
