Response-Based Online Structured Prediction by Stefan Riezler
01 Dec 2014

In the lab meeting this week, on Wed Dec 3ed, we will be hosting Stefan Riezler from Heidelberg University. He is going to give a talk about Response-Based Online Structured Prediction (with Applications to Grounded Statistical Machine Translation). The meeting will be at TASC1 9204 West 10:30am.

ABSTRACT:
In response-based structured prediction, instead of a gold-standard structure, the learner is given a response to a predicted structure. Different types of environments such as an extrinsic task, a computer program, or a human, can respond in form of a ranking, an acceptance/rejection decision, or an improvement of the predicted structures. In this talk, we present three instantiations of response-based learning scenarios for grounded statistical machine translation (SMT), where response signals are elicited by embedding SMT into cross-lingual information retrieval, into multilingual database access, and into human corrections of translations.

BIO:
Prof. Stefan Riezler has been appointed full professor and head of the chair of Linguistic Informatics at Heidelberg University in 2010, after spending a decade in the world’s most renowned industry research labs (Xerox PARC, Google). He received his PhD in Computational Linguistics from the University of Tübingen in 1998, and then conducted post-doctoral work at Brown University in 1999. Prof. Riezler’s research focus is on machine learning and statistics applied to natural language processing problems, especially for the application areas of natural-language based web search and statistical machine translation.
