1. 打开VS的安装目录,找到devenv.exe,右键,选择“兼容性疑难解答”. 2. 选择“疑难解答程序” 3. 选择“该程序需要附加权限” 4. 确认用户帐户控制后,点击测试程序,不然这个对话框不让你点下一步 5. 点击“测试程序”后,VS会以管理员权限启动.这就对了. 6.回到兼容性疑难解答对话框,点击下一步,然后选择“是,为此程序保存这些设置”,大功告成.…

对哨兵1号的多时相双极化SAR数据进行预处理,得到18个日期的VV和VH共36景影像,通过ANOVA和JM距离分析,选其中ANOVA得到的F值最高的6景影像.真值用LC8数据和地面调查,目视解译得到标签.将6景影像合到一个数据中即6波段数据,输入到UNET中,网络结构同原始UNet,除了在conv和relu中间加了BN. 这里引发了思考,BN层到底是加在哪里的,因为keras里的conv2d层是可以直接加激活函数的,中间加BN就要拆开写了.提出BN的论文里似乎就是加在了conv和relu中间.其…

How much training data do you need?   //@樵夫上校: 0. 经验上,10X规则(训练数据是模型参数量的10倍)适用与大多数模型,包括shallow network. 1.线性模型可以应用10X的经验规则,模型参数是特征选择后的数量(PCA等方法).2.NN可以将10X规则当做训练数据量的下限. The quality and amount of training data is often the single most dominant factor t…
