One hot encoding of string categorical features - Stack Overflow
https://stackoverflow.com/questions/35107559/one-hot-encoding-of-string-categorical-features
Web ResultWhat's the best way to preprocess this data using Scikit-Learn? On first instinct, you'd look towards Scikit-Learn's OneHotEncoder. But the one hot encoder doesn't support strings as features; it only discretizes integers. So then you would use a LabelEncoder, which would encode the strings into integers. But then you have to apply the label ...
