My work here was generally about natural language processing, computational linguistics, speech recognition and understanding, etc.
I enjoy jogging regularly and have participated in several local 5K events back in Ohio.
I'm also a big fan of Haruki Murakami (村上春树)'s novels, do check out "Pinball, 1973", "A Wild Sheep Chase", and "The Wind-Up Bird Chronicle" if you have time.
School of Computer Science, CMU: Graduate Research Assistant (2011.8 – Now)
Aimed to develop rapid methods of keyword spotting among large collections of audio.
Sped up the Keyword Spotting system by 15 times by implementing a parallel processing framework using client-server model.
Implemented a script that automatically optimizes a set of parameters during confusion-network generation. Improved the accuracy of the Keyword Spotting system by 16% on average.
Miso the Ontology Learner (May 2009 - August 2009)
Automated knowledge extraction system that used NLP techniques such as POS-tagging, parsing and regular expression to extraction knowledge from a textbook to build an ontology.

Source code will be given upon request.
Language classifier that detects 17 natural languages in the world.
Trained the classifier with language specific features extracted from character-level N-Gram of text from each language.
Converted the testing language text into one-dimensional N-Gram vectors and then classify.
Road Trip to the West (December 2010 - January 2011)
Liyang Zhao, Han Zhu and I drove for 17 days and completed the road trip to California and back.
(K, L, M are places we visited in another trip in 2010, and N is Oxford, OH - where we started).
