Research Groups: Week of November 12-16

Tuesday, November 13, 1:30 PM - 2:30 PM, PT266
Computational Linguistics Group, Department of Computer Science
Eric Corlett (Ph.D., Computer Science): "Probability and program complexity for NLP."
Probabilistic models used in NLP often come from general frameworks into which otherwise difficult-to-define tasks can be embedded. The power of these frameworks can lead to situations in which traditional measures of descriptive complexity, such as worst-case running time, can overestimate the cost of running our algorithms. In this talk I look at how practical and theoretical complexities can differ by investigating the Most Probable Sentence problem, which was shown to be NP-complete by Khalil Sima'an in 2002. I show that linguistic entropy can be used to formulate a more natural bound for the running time of this problem, as well as its error of approximation.

Wednesday, November 14, 12:00 PM - 2:00 PM, Bissell Building 113
