Research Areas:

  • Machine Learning (Manifold Learning, Transfer Learning, Representation Learning and Deep Learning);
  • Application of Machine Learning in Natural Language Processing (NLP), Data Mining and Information Retrieval (IR)
  • Knowledge graphs on finance, science & technology



  • 2018.03-Now:  Co-Founder of FMeasure Inc. (explainable AI and knowledge graph for finance)
    • We track and analyze financial data (company filings, earning calls, financials, patents, papers, trademarks, news, social media, recent investment activities, funding rounds and acquisitions, etc) in real-time, and integrate all such data in a large financial knowledge graph. Leveraging this knowledge graph and a set of built-in natural language processing and machine learning components,  we deliver results with explanations for a number of tricky financial tasks like acquirer recommendation, market research report generation and technology investing. 
  • 2018.05-Now: Founder of (sci-tech knowledge graph and text analysis platform for scientific literature)
    • Lead a team to develop and manage, a science-technology knowledge graph and text analysis platform for scientific literature tracking, search and summarization. We currently track ~250 research areas from the following subjects: Biology, Computer Science, EE and System Science, Finance, Health Science, Math, Physics, and Statistics, and maintain a science-technology knowledge graph constructed from more than 100M documents. Four major services are offered to users: daily paper digest, conference digest, real-time topic tracking and search (paper, patent, grant, expert). Several features we offer are unique: (1) Our system automatically produces a one sentence summary for every new paper added to our system to help readers quickly decide if a paper is worth reading or not; (2) Our paper search service returns results with related papers, patents and grants such that people can quickly check if a similar idea has already been published, patented or funded. We also provide expert lookup, co-author lookup and patent lawyer search services.
