AI Seminar-Topics in Constraint Satisfaction and Weighted Constraint Satisfaction
Fri, Oct 17, 2014 @ 11:00 AM - 12:00 PM
Information Sciences Institute

Speaker: Satish Kumar Thittamaranahalli , USC
Talk Title: Topics in Constraint Satisfaction and Weighted Constraint Satisfaction
Series: Artificial Intelligence Seminar
Abstract: In this talk, I will present two ideas: (a) the idea of "Smoothness" in constraint satisfaction; and (b) the idea of "Constraint Composite Graphs" in weighted constraint satisfaction. Smoothness helps us identify tractable classes of constraint satisfaction problems with important implications in such diverse areas as temporal reasoning, logical filtering, and distributed problem solving. In weighted constraint satisfaction, Constraint Composite Graphs yield a long-pursued unified mathematical framework for exploiting the graphical structure of the constraint network as well as the numerical structure of the weighted constraints.
Biography: Dr. Satish Kumar Thittamaranahalli (T. K. Satish Kumar) is a Research Scientist at the University of Southern California. He has published extensively on numerous topics in Artificial Intelligence spanning such diverse areas as Constraint Reasoning, Planning and Scheduling, Probabilistic Reasoning, Combinatorial Optimization, Approximation and Randomization, Heuristic Search, Model-Based Reasoning, Knowledge Representation and Spatio-Temporal Reasoning. He has served on the Program Committees of many international conferences in Artificial Intelligence and is a co-winner of the Best Student Paper Award from the 2005 International Conference on Automated Planning and Scheduling. Dr. Kumar received his PhD in Computer Science from Stanford University in March 2005. In the past, he has also been a Visiting Student at the NASA Ames Research Center, a Postdoctoral Research Scholar at the University of California, Berkeley, a Research Scientist at the Institute for Human and Machine Cognition, a Visiting Assistant Professor at the University of West Florida and a Senior Research and Development Scientist at Mission Critical Technologies

NL Seminar- Beyond Parallel Data: Joint Word Alignment and Decipherment Improves Machine Translation [EMNLP Practice Talk]
Fri, Oct 17, 2014 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Qing Dou, USC/ISI
Talk Title: Beyond Parallel Data: Joint Word Alignment and Decipherment Improves Machine Translation [EMNLP Practice Talk]
Series: Natural Language Seminar
Abstract: Inspired by previous work, where de- cipherment is used to improve machine translation, we propose a new idea to combine word alignment and decipher- ment into a single learning process. We use EM to estimate the model parameters, not only to maximize the probability of parallel corpus, but also the monolingual corpus. We apply our approach to im- prove Malagasy-English machine transla- tion, where only a small amount of paral- lel data is available. In our experiments, we observe gains of 0.9 to 2.1 Bleu over a strong baseline.
Biography: Qing Dou is a fifth year Ph.D. student at ISI. He works with Professor Kevin Knight on various decipherment problems and its application to different Natural Language Processing tasks.
