Project Experience

Deep Keyphrase Generation
We apply a deep generative model (encoder-decoder model) on the task of keyphrase summarization, which provides a novel perspective on this long-studied problem. A copy mechanism is effectively employed to enhance the model with extractive ability. Experiments demonstrate our model not only outperforms baselines on keyphrase extraction benchmarks but also has the capability of predicting semantically related phrases.
Kaggle: Springleaf Market Response
A large-scale classification task aims to locate the target users for advertising. More than 290,000 customer records with nearly 2,000 anonymized features are used in this study. A complete pipeline has been implemented in this study, including data analysis (statistics and visualization), feature engineering (selection, reduction) and classification (ensemble models).
Citation Semantic Classification
Citation performs in different semantic roles in scientific papers. A fine-grined classification is conducted, based on support vector machine with multiple types of semantic features (n-grams, pos-tagging, linguistic pattern, typed dependency, entity etc.).
National Olympiad in Informatics in Provinces
The most influential programming competition for senior high school students in China. Similar to ACM Programming Contest, the NOIP require the contestants to show great IT skills as problem analysis, design of algorithms and data structures, programming and testing. The winners (less 1% of contestants) are recommended and accepted to top universities in China.
