㈣ python 字符串处理 SQL查询语句

>>> base = """("%(k)s" = '%(v)s')"""
>>> print ' and '.join([base % dict(k=k, v=v) for k,v in dict(name='tim', email='[email protected]').items()])

("email" = '[email protected]') and ("name" = 'tim')
>>>

另外: 强烈建议不采用拼接字符串的方式定义SQL,而是采用参数

㈤ 遥感数字图像定量反演的方法

遥感数字图像可以用Google earth engine python API来实现定量反演。

用基于GEE的pythonAPI，主要实现以下内容：

站点数据和遥感影像匹配。

利用机器学习/深度学习模型进行匹配数据的训练。

将训练的模型用于GEE上的影像数据，实现参数反演结果成图。

提取影像的metedata，作为模型的输入数据。

注意，直接采用img.get( )得到的是computerobject这种类型的结果，无法在机器学习模型中输入和计算，应加上.getInfo()。

总结如下：

反演，在人工智能领域又称为人工智能反演(inversion with artificial intelligence),是指能够模仿人类智能的计算机程序系统即人工智能专家系统，它具有学习和推理的功能。例如模拟退火最优化系统、人工神经网络系统等。

在反问题求解过程中应用人工智能的方法技术，引导局部或全局寻优，这种反演方法称为人工智能反演技术。
