Implementation of the Feligi-Holt algorithm using the ErrorLocalizer base class.
Given a set of validation rules and a dataset the Feligi-Holt algorithm finds for each record
the smallest (weighted) combination of variables that are erroneous (if any).
Note
Most users do not need this class and can use locate_errors().
errorlocalizer implements feligi holt using a MIP-solver. For problems in which
coefficients of the validation rules or the data are too different, you should consider scaling
the data.
