This implementation globally replaces all missing values and transforms nominal attributes into binary ones. It also normalizes all attributes by default. (Note that the coefficients in the output are based on the normalized/standardized data, not the original data.)<br/> <br/> For more information on the SMO algorithm, see<br/> <br/> Alex J.
