We consider multi-label prediction problems with large output spaces under
the assumption of output sparsity -- that the target (label) vectors have small
support. We develop a general theory for a variant of the popular error
correcting output code scheme, using ... | arxiv topic:cs.LG |

Although blazars are thought to emit most of their luminosity in the
