I am a Ph.D student in Language Technologies Institute, School of Computer Science, Carnegie Mellon University. Currently I am working with Stephan Vogel on GALE project, working on improving word alignment for phrase-based machine translation systems and and parallelizing the training pipeline of machine translation.
Also, I am working with Stephan Vogel and Noah Smith on INCA project, building open source distributed statistical machine translation system on clusters, especially for MapReduce frameworks such as Hadoop.
I worked in Microsoft Research in Redmond, WA from April 2011 to July 2011 as an intern. I worked closely with Will Lewis, Chris Quirk and Mei-Yuh Hwang. The research topic is incremental training for word alignment.
My current work focus on utilizing Semantic Role information to assist machine translation.
I am editing several pages in Wikipeida Chinese, if you know Chinese, please help me improve them: Statistical Machine Translation Machine Translation
Research
I focus on parallelizing the pipeline of machine translation framework, released software packages such as Multi-Threaded GIZA++ MGIZA++ and Parallel GIZA++ PGIZA++ . And an internal version of parallel phrase extraction tool Chaksi is being developped and testing on Yahoo's M45 cluster. All these work will be part of INCA project, funded by NSF.
Also, I am interested in improving the word alignment quality for machine translation, and looking forward to integrating syntactical information into phrase based machine translation.
Before joining LTI at 2007, I worked on speech recognition, worked mainly on ASR decoders. Please refer to my CV for more detail on the research.

Software
Please visit http://geek.kyloo.net/software for a list of my softwrae.
- Chaksi: A software package for training phrase-based machine translation system on Hadoop clusters, together with MGIZA it can train large scale model in hours.
- MGIZA : Multi-threaded GIZA. It is a extended and optimized version of GIZAPP, which can run multi-threaded, and provide additional functionalities/optimizations such as:
- Resume training from previous models. You may restart training from any step give previous model.
- Memory usage optimization. Eliminate duplicated tables in memory, which may save hundreds of megabytes of memory. It is crucial for distributed alignment.
- Integrate with Chaksi. The verison is fully integrated with Chaksi and therefore can be run on Hadoop clusters. (Currently only work for Hadoop 0.20.1+)

My Gadgets
(From oldest to newest)- Palm Treo650 (Used to be my phone and my notebook and Gameboy simulator)
- N800 (My favorite, although I do not bring it around, I use it to read wikipedia every night, and it killed Treo with GarnetVM )
- MIO 520 (PNA, running MIO Mapper as well as iGo 8, hacked and being used as Skype phone when I forget to bring N800. SDIO Wifi card required, of coz)
- EeePC 1000h (It is a laptop, but small enough to replace most gadgets, I am now playing around with it. Less fun with Windoz installed anyway)
