针对表情识别时出现参数量大和识别能力弱等问题,提出一种基于卷积网络人脸表情识别方法。引入改进型残差模块,在减少参数量的同时增强对表情区域的关注;利用通道-空间注意力机制对网络提取的表情区域实现不同维度和位置上的权重分配,专注于表情关键点中细微差别特征信息;利用细节模块进一步提取深度特征信息。为得到更高准确度,引入联合损失函数延长类外距离,缩短类内距离以提高表情识别准确度。本文将此网络运用到数据集FER2013、CK+中,实验结果表明:本算法平均识别率分别为63.91%、97.98%,参数量为11.34 M。与VGG网络、残差网络等对比,该模型不仅提高了识别率,还减少了冗余参数量。

现阶段,我国城镇职工基本养老保险面临灵活就业人员与私营企业职工达到最低缴费年限后不再缴费的挑战,即“参而不缴”难题。本文基于基金可持续性与养老金替代率视角,运用精算模型模拟适度最低缴费年限。研究发现:提高最低缴费年限能增加养老金替代率,但会扩大未来养老保险基金累计赤字;在不延迟退休年龄的情况下,兼顾基金可持续性和养老金替代率的适度最低缴费年限为21~22年;延迟退休年龄能减少未来基金累计赤字并提高养老金替代率,当女性退休年龄延迟至60岁,适度最低缴费年限为26~27年,当男女退休年龄延迟至65岁,适度最低缴费年限为30~31年。上述结论均通过敏感性测试。因此,本研究建议最低缴费年限在现行15年的基础上延长5年,并根据渐进式延迟退休年龄政策,再逐步延长5~10年,实施25~30年的最低缴费年限政策,以促进养老保险基金可持续运行并提高养老金替代率。

当前,草原畜牧业发展与草原生态可持续保护间的矛盾日益凸显,如何协调二者之间的关系成为了当前草原管理的重要内容。考虑引入生态补偿政策,构建了政府草原放牧管理与牧民放牧决策的微分博弈模型,探讨了双方的动态最优决策以及草原生态水平的演变规律,阐释了生态补偿政策的效用机理。研究表明:在草原放牧管理中,政府和牧民采取状态依赖的动态决策是实现草畜平衡、最大化利用草原资源的有效途径;政府实施草原生态补偿政策可以在保障牧民收益的同时取得更好的草原生态保护成效;在草原生态补偿政策推行过程中,增加生态补偿力度可以有效激励牧民合理减牧,进而促进草原生态水平的提升。
