Professional Experiences

• May 2017 - Present: Yahoo! Labs Collaborative Research Program, London, United Kingdom
  • Established a long-term cooperation with Yahoo! Research on my PhD work for inferring users’ needs and tasks on mobile devices. By leveraging the large-scale dataset of real-life app usage logs, we proposed and implemented:
    • a framework for tackling the novel app engagement prediction problem on simultaneously predicting both what app user will use and how long the user will stay on that app
    • an enhanced app usage prediction model based on the user cohort modelling approach
    • task detection models based on supervised machine learning classifiers with various features and discovered common mobile task types that span multiple apps based on the clustering approach
    • demographics prediction models based on users? mobile app tasks with deep learning models (i.e.CNN and LSTM)
• Aug 2015 – Nov 2016: Dartmouth College
  • Research Assistant, NH, United States
    • Implemented the online learning of GMM (Gaussian Mixture Models) in Matlab
    • Optimized the online learning GMM method by several strategies (i.e., stratified sampling, SVD constraints, and scalar covariance update function) for simulating the pixel intensities of the imagein a more accurate and robust fashion.
    • Teaching Assistant in Courses : Problem Solving via Object-Oriented Programming; Machine Learningand Statistical Data Analysis; Computer Networks; Full-stack Web Development
• June 2014 – Sep 2014: IBM Research
  • Assistant Researcher Intern, Beijing, China
    • Won the 1st Prize of Extreme Blue Innovation Project Contest by the BlueLink
    • Participated in designing and realizing a system called BlueLink, which is an open IoT (Internet of Things) cloud platform to help people link with intelligent devices friendly
    • Generated the model for predicting future air quality based on historical data of pollutants and environmental factors
• Apr 2012 – Nov 2012: Intel
  • Technical Assistant Intern, Beijing, China
    • Analyzed the purchasing history and products information of existing customers to infer the potential customers and their preferred products.
    • Communicated with customers for increasing the market share of our products
• Nov 2011 – Mar 2012: Baidu
  • Software Development Intern, Beijing, China
    • Actively involved in the development (i.e., PHP programming) of the product upgrading program in Baidu Library group.
