Combining statistical and relational learning receives currently a lot of attention. The majority of statistical relational
learning approaches focus on density estimation. For classification, however, it is well-known that the performance of such
generative models is often lower than that of discriminative classifiers. One approach to improve the performance of generative
models is to combine them with discriminative algorithms. Fisher kernels were developed to combine them with kernel methods,
and have shown promising results for the combinations of support vector machines with (logical) hidden Markov models and Bayesian
networks. So far, however, Fisher kernels have not been considered for relational data, i.e., data consisting of a collection
of objects and relational among these objects. In this paper, we develop Fisher kernels for relational data and empirically
show that they can significantly improve over the results achieved without Fisher kernels.
