Abstract: Learning from electronic medical records (EMR) is challenging due to their relational nature and the uncertain dependence between a patient's past and future health status. Statistical relational learning is a natural fi t for analyzing EMRs but is less adept at handling their inherent latent structure, such as connections between related medications or diseases. One way to capture the latent structure is via a relational clustering of objects. We propose a novel approach that, instead of pre-clustering the objects, performs a demand-driven clustering during learning. We evaluate our algorithm on three real-
world tasks where the goal is to use EMRs to predict whether a patient will have an adverse reaction to a medication. We fi nd that our approach is more accurate than performing no clustering, pre-clustering, and using
expert-constructed medical heterarchies.
