群体行为往往能产生远超个体行为的价值和复杂度。为了在个体智能的基础上更有效地衍生出群体智能,需要基于群体熵来科学地衡量群体智能水平,并以群体熵为引导目标,推动群体智能的增强和演进。针对这个重要的科学问题,以无人小车群体为研究对象,提出基于参数共享和群体策略熵的多智能体soft Q learning算法,通过共享智能体的观测信息,并结合最大熵强化学习方法,实现探索型任务中群体策略的持续学习更新。同时,通过将群体熵定义为度量工具,刻画群体学习中熵变化模式,实现对群智汇聚过程的定量分析。

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.

ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.
