Yuan Luo, a PhD student in Professor Peter Szolovits’ Clinical Decision Making Group, has been awarded the first prize at the Natural Language Processing Doctoral Consortium in 2013 American Medical Informatics Association’s Annual Symposium. The presentation, “Subgraph Augmented Non-Negative Tensor Factorization (SANTF) in Medical Natural Language Processing”, describes a new method for jointly modeling the interactions among higher-order features and atomic features by integrating them into the learning objective, at the same time performing dimensionality reduction in all types of features. The method not only leads to improved clustering of patient phenotype, but also produces latent groups of features that are consistent with clinical insights.
