Question
- import pandas as pdfrom sklearn import preprocessingdata = {"gender": list('FMMF')}df = pd.DataFrame(data)one_hot = preprocessing.OneHotEncoder(sparse_output=False,drop='if_binary')new_df = pd.DataFrame(one_hot.fit_transform(df), columns= one_hot.get_feature_names_out())new_dfWhat is the output of the code above? Gender_M01.010.020.031.0 Gender_FGender_M00.01.011.00.021.00.030.01.0 Gender_FGender_M01.00.010.01.020.01.031.00.0 Gender_M00.011.021.030.0
Solution
The output of the code above will be a DataFrame that represents the one-hot encoding of the 'gender' column from the original DataFrame. The one-hot encoding process converts categorical variables into a form that could be provided to machine learning algorithms to improve prediction.
The output will look like this:
Gender_F Gender_M
0 1.0 0.0
1 0.0 1.0
2 0.0 1.0
3 1.0 0.0
Here, 'Gender_F' and 'Gender_M' are the new columns representing the 'gender' column from the original DataFrame. The values in these columns are either 0 or 1. For example, in the first row, 'Gender_F' is 1 and 'Gender_M' is 0, indicating that the gender for the first record was 'F'.
