    Talk Title: Structured Predictions: Practical Advancements and Applications in Natural Language Processing

    Abstract: This lecture satisfies requirements for CSCI 591: Research Colloquium.

    Many machine learning problems involve making joint predictions over a set of mutually dependent output variables. The
    dependencies between output variables can be represented by a structure, such as a sequence, a tree, a clustering of nodes, or a graph. Structured prediction models have been proposed for problems of this type, and they have been shown to be successful in many application areas, such as natural language processing, computer vision, and bioinformatics. In this talk, I will describe a collection of results that improve several aspects of these approaches. Our results lead to efficient learning algorithms for structured prediction models, which, in turn, support reduction in problem size, improvements in
    training and evaluation speed. I will also discuss potential risks and challenges when using structured prediction models.
