Personal

Welcome to the homepage of Martin Ratajczak.

Currently I work within the Human Language Technology and Pattern Recognition Group at the Chair of Computer Science 6 of the RWTH Aachen University.

The main research topics of the chair are

• Pattern Recognition
• Automatic Speech Recognition
• Statistical Machine Translation
• Image Processing

My personal research topics and interests are

• Conditional Random Fields (CRFs)
• Maximum Entropy Markov Models (MEMMs)
• Application of MEMMs and CRFs to sequence labeling tasks: Mainly statistical machine translation, tagging and sign language translation
• Discriminative Word Lexicon Models (DWLs)
• Feature Selection
• Speed up training of log-linear models
• Text classification

You can find me in room 6127 of our department, call me at +49 (241) 80-21618 or write an e-mail to ratajczak [-at-] i6.informatik.rwth-aachen.de.
