This article takes the linear algebra course as an example to explore ideological and political elements. The article first identifies five directions for carrying out ideological and political education in linear algebra courses. Based on this, it explores ideological and political elements in depth from the teaching content, constructs a knowledge system that fully integrates knowledge points and ideological and political elements, and subtly infiltrates ideological and political education into students in teaching.展开更多
文摘针对合成孔径雷达(Synthetic Aperture Radar,SAR)图像目标识别算法识别准确率极易受到斑点噪声影响,且模型容易出现过拟合的问题,提出了一种基于Frost滤波和改进的卷积神经网络的目标识别方法。利用Frost滤波算法对SAR图像进行了滤波处理,减少了相干斑噪声;对CNN网络进行改进,建立了一个SAR图像目标识别模型,在网络中引入L2正则化和Dropout结构,抑制过拟合现象的发生;采用Adam优化算法,提高模型的收敛效率;最后采用组合的数据增强方法,扩充SAR图像数据集,进一步提高识别的准确率。利用美国运动和静止目标获取与识别(Moving and Stationary Target Acquisition and Recognition,MSTAR)SAR图像数据进行实验,综合识别准确率可以达到98.06%,结果表明本文所提的方法具有更好的识别效果。
