Visiting Researcher, 07/2015 to 12/2015 TCL Research America – San Jose, CA
Worked on developing Natural Language Understanding (NLU) engine in Python.
Developed web crawler with Scrapy to crawl large scale online raw text data. Preprocessed data with stemming and lemmatization and extracted sample user queries by using regular expression and comparing cosine/euclidean similarity with established gold standard dataset.
Design and implement an automatic system for evaluating third party NLU engine, including Nuance, Houndify and Robinlabs.
Designed and Developed RESTful Web services for NLU engine in Python by identifying entities and user intents from user queries and stored results in JSON format. Designed and Developed logger application components for the NLU engine. Algorithms were pushed on BitBucket.
Research Assistant, 02/2013 to 05/2015 Drexel University – Philadelphia, PA
Worked on machine learning project in Matlab/Java/SQL.
Developed web crawler to collect user data from CiteULike, stored data in MySQL database.
Proposed novel clustering models for feature learning with Nonnegative Matrix Factoriztoin (NMF). Designed and Developed boosting algorithms for the clustering models.
Implemented cross-fit experiments with k-means, NMF and GNMF and the performance of new clustering models was statistically better than others.
