  • Lifelong Machine Learning Tutorial, IJCAI-2015, July 25-31, 2015, Buenos Aires, Argentina
• Open World Machine Learning, Classification, or Recognition: one form of Lifelong Learning
  • Closed world assumption: classic machine learning assumes that test instances must be from training classes. Not true in most real-world environments.
  • Open-world learning: Identify instances of unseen classes during testing or application and incrementally learn the new classes.
• Continuous Learning in Chatbots
  • See this 2018 paper "Towards a Continuous Knowledge Learning Engine for Chatbots."
• PU Learning - Learning from Positive and Unlabeled Examples (Set Expansion is also a PU learning problem)
• Download our LPU system - LPU and Spy-EM (S-EM) system - S-EM
• Detect Fake Reviews and Fake Reviewers - Detect Opinion Spam
  • Detecting fake or deceptive opinions on review sites, facebook, Twitter, Weibo, and forum discussion sites
• Intent Mining - Mining user Intents or Intentions in Social Media Posts
  • Chapter 11 of my sentiment analysis book discusses this topic; also see this NAACL-HLT-2013 paper.
• Generate a Book Automatically using Web Content: Synthesize knowledge on the Web (See our WWW-2003 paper).
  • Given a topic, discover sub-topics and related concepts, and synthesize information from multiple Web pages to present a coherent and reasonably complete picture of the topic.

  • Download MDR; Two new systems are DEPTA and NET.
• Data Mining and Knowledge Discovery
  • Diagnostic Data Mining - Interestingness of Knowledge: Finding interesting and actionable knowledge.
    • We built a system in 2006, called Opportunity Map (also known as OM in Motorola). It was deployed in 2006 and is still in regular use in Motorola. Motorola has sold copies of the system to some Telco companies. There is also a patent, but unfortunately it is owned by Motorola, not us :-(.
  • Classification Based on Associations - Integrating Classification and Association Rule Mining
    • Download CBA - asociation rules based classification. You can also use the CBA implementation of Frans Coenen from Univesity of Livepool.
