Dear faculty and students,

We look forward to seeing you next Tuesday, September 19, at noon in NSH
3305 for AI Seminar sponsored by Apple. To learn more about the seminar
series, please visit the AI Seminar webpage

On Tuesday, Bhuwan Dhingra <http://www.cs.cmu.edu/~bdhingra/> will give the
following talk:

Title: Neural architectures for reading and reasoning over documents

Abstract: Reading and understanding natural language text is important for
AI applications which need to extract information from unstructured
sources. Models designed for this task must deal with complex linguistic
phenomena such as paraphrasing, co-reference, logical entailment, syntactic
and semantic dependencies, and so on. In this talk I will show how
architectural biases, motivated from such phenomena, can be built into
neural network models to boost machine reading performance.

The first half of the talk will focus on the Gated-Attention (GA) Reader
model for learning fine-grained alignments between natural language queries
and documents. The output of this model is a query-focused representation
of the tokens in the document, which is used to extract the answer to the
query. The second half of the talk will focus on extensions which utilize
prior knowledge in the form of linguistic annotations to model long term
dependencies in the document. Modeling long-term dependencies is the first
step towards the more ambitious goal of reasoning over distinct parts of a
document. Finally, I will discuss some of the key directions for future
research, in terms of both improving the models and utilizing them for
concrete applications.

This is joint work with Zhilin Yang, Hanxiao Liu, Russ Salakhutdinov and
William Cohen.
