㈣ python 字元串處理 SQL查詢語句

>>> 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: 強烈建議不採用拼接字元串的方式定義SQL,而是採用參數

㈤ 遙感數字圖像定量反演的方法

遙感數字圖像可以用Google earth engine python API來實現定量反演。

用基於GEE的pythonAPI，主要實現以下內容：

站點數據和遙感影像匹配。

利用機器學習/深度學習模型進行匹配數據的訓練。

將訓練的模型用於GEE上的影像數據，實現參數反演結果成圖。

提取影像的metedata，作為模型的輸入數據。

注意，直接採用img.get( )得到的是computerobject這種類型的結果，無法在機器學習模型中輸入和計算，應加上.getInfo()。

總結如下：

反演，在人工智慧領域又稱為人工智慧反演(inversion with artificial intelligence),是指能夠模仿人類智能的計算機程序系統即人工智慧專家系統，它具有學習和推理的功能。例如模擬退火最優化系統、人工神經網路系統等。

在反問題求解過程中應用人工智慧的方法技術，引導局部或全局尋優，這種反演方法稱為人工智慧反演技術。
