I have a huge dataset that needs to run a binary classification on it. Some features in the dataset are string, so cannot use them without converting to numeric values. I tried fit_transform and applied the RandomForest after and worked properly.
However, we are implementing a real-time system that time is a big issue! fit_transform is time-consuming. Any idea of how I can use string values or other libraries to convert string to digit as quickly as possible?
I also have access to Spark so if MLlib has something that can help please let me know!
