摘要：非完备、高动态有源干扰对抗作战环境下,现阶段针对库内多类型单一有源干扰样本所优化训练的静态模型,在面对库外类型多样、参数多变、组合方式多元的复合干扰时,模型无法快速更新且难以应对测试样本数非均衡问题。针对此问题,该文提出一种基于零记忆增量学习的雷达复合有源干扰识别方法。首先,利用元学习训练模式对库内单一干扰进行原型学习,训练出高效的特征提取器,使其具备对库外复合干扰特征有效提取能力。进而,基于超维空间和余弦相似度计算,构建零记忆增量学习网络(ZMILN),将复合干扰原型向量映射到超维空间并存储,从而实现识别模型动态更新。此外,为解决样本数非均衡下复合干扰识别问题,设计直推式信息最大化(TIM)测试模块,通过在互信息损失函数中加入散度约束,对识别模型进一步强化训练以应对非均衡测试样本。实验结果表明,该文所提方法在非均衡测试条件下对4种单一干扰和7种复合干扰进行增量学习后,平均识别准确率达到了93.62%。该方法通过对库内多类型单一干扰知识充分提取,实现对多种组合条件下库外复合干扰的快速动态识别。

摘要：刘熙载是中国古典诗歌艺术研究的集大成者,其诗学观、艺术观、美学观对王国维有重要影响。王国维的《人间词话》中表述的词史观及其对重要词人的评价,对诗词艺术的一些重要观点均借鉴或直接来自刘熙载的论述,这说明王国维的诗学体系除吸收西方美学因素外,也全面继承了中国传统诗学的精华。

摘要：公共艺术作为一种开放性、综合性强的艺术形式,在提升社区活力,促进社会互动、展现区域文化等方面发挥着重要作用。公共艺术通过作品呈现,充分调动群众的互动性和参与度,将作品、群众、空间环境等三者融合,实现相互交融、沟通和影响,这也是公共艺术交互项目的特性所在。而色彩作为最直观的表现形式,在公共艺术交互项目中至关重要。本文从色彩心理学的角度,研究公共艺术交互项目与色彩的内在联系,从作品的色彩表达切入,挖掘公共艺术在色彩方面所呈现的情感、认知和行为,引发公众共鸣,实现公共艺术的社会性交互。

摘要：南昌海昏侯刘贺墓中出土的贴金银釦长方漆盒,体现了制造者、使用者及所处大时代的价值取向与艺术倾向。对漆盒进行情境分析,其上金箔纹样构成了田猎场景,层层向上的银釦,不仅构成了四层纹饰,还体现了抽象的仙山意象。漆盒内侧画的虫子应是令人厌恶的昆虫椿象,是画工对观者的一次炫技,更是双方的隔空互动。
