Researchers propose CPPO (Cumulative Prefix-divergence Policy Optimization), a new reinforcement learning method that improves upon standard PPO approaches for LLM training by accounting for position-dependent effects and cumulative policy divergence. The method uses position-weighted thresholds and prefix budgets to better regulate token-level deviations during autoregressive generation, showing improved training stability and reasoning accuracy across model scales.
This study evaluates machine learning approaches for distinguishing asthma from COPD using pulmonary sound analysis, comparing MFCC matrices, log-mel spectrograms, and VAR models with CNN and GRU networks. MFCC representations with adaptive-length windowing achieved the best performance (F1-score 0.877), while sophisticated fusion strategies and data augmentation unexpectedly degraded results, emphasizing the importance of authentic clinical data.
Researchers have published a practical security guide designed to help non-technical users understand and mitigate risks associated with OpenClaw, an AI agent framework capable of autonomously executing complex tasks. The work identifies seven core risks, provides actionable defensive strategies, and offers an automated OpenClaw Skill to simplify security configurations for users without technical expertise.
Researchers propose Diffusion Forcing Planner (DFP), a new diffusion-based motion planning framework for autonomous driving that addresses temporal inconsistency in learning-based planners. By decomposing trajectories into history, current, and future segments with independent noise levels and applying annealed guidance, DFP produces more stable and controllable driving plans while avoiding the tendency to simply copy historical patterns.
Researchers introduce T1-Bench, a comprehensive benchmark for evaluating large language model-based agents across 25 domains with multi-step, multi-domain tasks that better reflect real-world complexity than existing benchmarks. The framework tests 12 models on structured reasoning, tool utilization, and conversational quality, with both automated and human evaluation methods.
Researchers have developed a systematic framework for conditioning Multimodal Large Language Models (MLLMs) with explicit personality traits, revealing that while personality induction improves certain tasks like image captioning, it can degrade performance on reasoning-heavy tasks like visual question answering. The study demonstrates that model behavior is dynamically modulated by both previous and current personality constraints, exposing fundamental challenges in personality modeling for multimodal AI systems.
Researchers introduce GASLoC, a decentralized pre-training algorithm that reduces communication overhead in distributed LLM training by enabling local optimizer steps and sparse peer communication instead of synchronous operations. The method demonstrates competitive or superior performance compared to existing approaches, particularly in heterogeneous bandwidth environments where worker speeds vary significantly.
RoboNaldo, a motion-guided curriculum reinforcement learning framework, enables humanoid robots to perform accurate soccer shots with significantly improved stability and power compared to prior approaches.

The system uses a router mechanism to partition inputs into task clusters and employs co-evolution strategies to optimize prompt configurations, achieving significant performance improvements over existing methods on heterogeneous data streams.
Researchers propose a new framework for supervised fine-tuning (SFT) of language models that reinterprets the training process as target distribution design rather than simple token likelihood maximization. The Q-target framework allows models to allocate probability mass flexibly across token alternatives, unifying existing SFT variants and demonstrating consistent performance improvements across reasoning tasks.
