Convering numerical data to categorical data

#1

how do I convert y_pred which is a numpy array like [0,1,0,1] to an array of neg and pos

#2

From what I understood, you want to one-hot encode the y_pred vector i.e. a conversion from [0, 1, 0, 1] to something like {“neg”: [1, 0, 1, 0], “pos”: [0, 1, 0, 1]}.

To do this directly, either use “to_categorical()” from “keras.utils” or if you don’t want to use keras, you can also do this pandas using “pd.get_dummies()”.

Let me know if you need usage examples too.
PS: Ensure y_pred is of type “int” or something related. Using “float” can give unexpected results.
