智能科学与技术学报, 2020 多智能体系统因其在工程、社会科学和自然科学等多学科领域具有潜在、广泛的应用性，在过去的 20 年里引起了研究者的广泛关注。实现多智能体系统的一致性通常需要求解相关矩阵方程离线设计控制协议，这要求系统模型精确已知。然而，实际上多智能体系统具有大规模尺度、非线性耦合性特征，并且环境动态变化，使得系统精确建模非常困难，这给模型依赖的多智能体一致性控制协议设计带来了挑战。强化学习技术因其可以利用沿系统轨迹的测量数据实时学习控制问题的最优解，被广泛用于解决复杂系统最优控制和决策问题。综述了利用强化学习技术 ...

野生动物学报, 2021 现代动物园中应用正强化行为训练来教授动物学习新行为或增加动物配合饲养员日常操作的期望行为。动物学习复杂期望行为过程中，需要先把要塑造的新行为分解为多个简单的步骤，再将每个小步骤组合起来达到最终期望的标准。福州动物园成年雄性山魈（Mandrillus sphinx）不易进笼，并在食物充足情况下，出现长时间蹲守投喂点，驱赶弱势群体成员的现象。训练员运用正强化行为训练实现强势动物能按指令过笼、在内室进食、允许群体成员获取食物，以及降低弱势动物的恐惧感，获得良好的效果。同时降低了饲养员的日常操作难度 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Although psychological factors such as emotion and engagement have gained increasing attention for their role in language learning success, a substantial gap remains in understanding the sources of boredom and its impact on learners’ engagement, whether behavioural, affective or cognitive, in languages other than English (LOTE).

Guangtongxin yanjiu, 2021 在大力发展智能电网的背景下，支撑电网运转的电力光通信网规模日趋庞大，其承载的业务更加多样化。然而电力光通信网的业务路由规划主要以最短路径算法为主，导致电力光通信网存在业务重要度分布不均衡，从而导致网络局部风险过高的问题。针对上述现状，文章采用深度强化学习技术，以网络业务风险均衡为目标，提出了基于强化学习的电力光通信网风险均衡路由算法。该算法考虑业务重要度分布情况、链路容量和链路光信噪比，实现了电力光通信网风险均衡化。文章选取某省电力通信子网验证方案的有效性，研究结果表明 ...

智能科学与技术学报, 2022 群体知识图谱是指通过群体协作，以去中心化或分布式方式管理和维护的知识图谱。相比现有的集中式管理的知识图谱，群体知识图谱具备知识确权、隐私保护、众包激励、可信溯责等特点。尝试探讨构建或应用群体知识图谱平台面临的技术挑战。其中分布式知识迁移考虑在一个分散自治的框架下，通过实现不同来源的多个知识图谱之间的知识迁移，缓解单个知识图谱的知识不完备问题。其主要难点是在充分保护知识的自治所有权的前提下，尽可能共享有用的知识，以增强各自的知识图谱表示。联邦式图谱推理也是考虑在一个分布式环境下 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Acknowledging the limitations of existing measurement instruments in adequately capturing the distinct cognitive processes (e.g., form‐focused vs. meaning‐focused) involved in informal digital learning of English (IDLE), this paper asserts a pressing need to develop and validate robust instruments that measure form‐focused and meaning‐focused ...
