Hi all!

A gentle reminder for today's talk by Andreas Vlachos
(http://www.biostat.wisc.edu/~vlachos/) from University of Wisconsin Madison.
Details follow.

When: 2 pm, April 8 (Friday)

Where: 3405, Siebel Center

Title: Bridging the Gap between Pipelines and Structured Prediction in
Biomedical
Event Extraction

Abstract:
We develop a structured prediction approach to biomedical event extraction
using the Searching to Learn framework which converts the problem of
structured prediction into multiple cost-sensitive classification (CSC) tasks
whose parameters are learnt jointly.
We evaluate our performance on the BioNLP 2009 shared task datasets and show
that SEARN improves the performance of a pipeline of classifiers learnt
independently by 7 points in F-score, while maintaining its ease of
implementation. In this process, we highlight some important aspects of the
framework and in particular the choice of CSC learning algorithm.

Hoping to see y'all

Thanks!
Rajhans
