DESCRIPTION

Presentation given at Mendeley's Open Day 2014. A high level description of what machine learning is used for in Mendeley before going a little deeper in user profiling and recommender systems. I am responsible for the first part of the presentation only. Lili Tcheang and Maya Hristakeva created parts II and II respectively.

TRANSCRIPT

  • 1. Machine Learning@Mendeley Part I: Introduction Presenter Name: Kris Jack (@_krisjack), Lili Tcheang and Maya Hristakeva Presenter Title: Chief Data Scientist, Data Analyst, Senior Data Scientist Date: 01/10/14
  • 2. What is Machine Learning (ML)? Applications of Machine Learning Spam Detection for Email Personalised Search (e.g. Google, Bing) Speech Recognition Recommender System (e.g. Amazon, Netflix) Definition: Software that improves itself with experience (e.g. exposure to new data)
  • 3. Why is ML Important to Mendeley? Information Extraction Metadata extraction Catalogue: Crowdsourcing Duplicate detection User Profiling Descriptive and Predictive Recommendations Contextualise research Make new discoveries
  • 4. A Closer Look at 2 ML Applications User Profiling: What are our users currently doing with Mendeley? Recommender Systems: How are we helping researchers with their work?
  • 5. Machine Learning@Mendeley Part II: What kind of User are you? User Profiling Presenter Name: Kris Jack (@_krisjack), Lili Tcheang and Maya Hristakeva Presenter Title: Chief Data Scientist, Data Analyst, Senior Data Scientist Date: 01/10/14
  • 6. Heres What We Did Take 2000 users. Extract 40 activities recorded for those 2000 users. See how those users cluster according to their activities.
  • 7. What were those activities? Social Group invites New followee Posts etc Productivity Reading Writing Search etc
  • 8. Heres how people cluster -0.4 -0.2 0 0.2 0.4 0.6 0.8 1 1.2 1.4 -0.4 0.1 0.6 1.1 1.6 More Productivity Social ProductivityBoth
