How to use OneHotEncoded data into Isolation Forest?
I have two columns in my dataframe and both are categorical. One of these columns contains misspellings and I want to do outlier detection in it and trying to use Isolation Forest.
I have applied OneHotEncoding on both columns but I don't know how to use this numpy array into Isolation Forest. I would appreciate some help. Here's my code for OneHotEncoding
newDF=pd.DataFrame()
labelEncoder = LabelEncoder()
newDF = df.apply(labelEncoder.fit_transform)
enc = OneHotEncoder()
enc.fit(newDF)
onehotlabels = enc.transform(newDF).toarray()
print(onehotlabels)
python one-hot-encoding
