Abstract
Training datasets for learning of object categories are
often contaminated or imperfect. We explore an approach
to automatically identify examples that are noisy or trouble-
some for learning and exclude them from the training set.
The problem is relevant to learning in semi-supervised or
unsupervised setting, as well as to learning when the train-
ing data is contaminated with wrongly labeled examples
or when correctly labeled, but hard to learn examples, are
present. We propose a fully automatic mechanism for noise
cleaning, called 'data pruning', and demonstrate its suc-
cess on learning of human faces. It is not assumed that the
