Multi-labeled classification has also been attempted using generative models, although discriminative methods are known to be more accurate. McCallum [9] gives a generative model where each document is probabilistically generated by all topics represented as a mixture model trained using EM. The class sets which can generate each document are exponential in number and a few heuristics are required to efficiently search only a subset of the class space. The Aspect model [10] is another generative model which can be naturally employed for multi-labeled classification, though no current work exists.

22–30, 2004. © Springer-Verlag Berlin Heidelberg 2004 Discriminative Methods for Multi-labeled Classification 23 In this paper, we present algorithms which use existing discriminative classification techniques as building blocks to perform better multilabeled classification. We propose two enhancements to existing discriminative methods. First, we present a new algorithm which exploits correlation between related classes in the label-sets of documents, by combining text features and information about relationships between classes by constructing a new kernel for SVMs with heterogeneous features.
