Research interest in cotraining is increasing which combines information from usually two classi ers to iteratively increase training resources and strengthen the classi ers. We try to select classi ers for cotraining when more than two representations of the data are available. The classi er based on the selected representation or data descriptor is expected to provide the most complementary information as new labels for the target classi er. These labels are critical for the next learning iteration. We present two criteria to select the complementary classi er where classi cation results on a validation set are used to calculate statistics for all the available classi ers. These statistics are used not only to pick the best classi er but also ascertain the number of new labels to be added for the target classi er. We demonstrate the e ectiveness of classi er selection for semantic indexing task on the TRECIVD 2013 dataset and compare it to the self-training.
