An explanation of LabelEncoder and OneHotEncoder in python data processing.
As shown below:
# Simply put LabelEncoder is a numbering system for discrete numbers or text. from import LabelEncoder le = LabelEncoder() ([1,5,67,100]) ([1,1,100,67,5]) exports： array([0,0,3,2,1]) The #OneHotEncoder is used to dimensionally expand the data representing the classification: from import OneHotEncoder ohe = OneHotEncoder() ([[1],[2],[3],[4]]) ([2],[3],[1],[4]).toarray() exports：[ [0,1,0,0] , [0,0,1,0] , [1,0,0,0] ,[0,0,0,1] ]
