Table 1 Example of classification results for a given attribute (i.e., gender) using three different algorithms. Note that an algorithm that can output unknown produces higher performance measures than one that commits the same amount of errors (e.g., algorithm B vs algorithm A). For gender estimation and for the class female, a true positive is a female estimated as female; a false negative is a female estimated as male; and a false positive is a male estimated as female
