Webinar Recording

Some of the questions asked and answered in the webinar include (more questions answered in the webinar can be found here):
  • Do you collect the tag info "is taught by" in what you will learn about this course? Some courses have this info under "About this Course."
  • Do you have your own search engine or do you use something like solr? was it difficult to add your new module to existing infrastructure?
  • Re: R vs Python: I teach Python, but have no experience of R. I read a recent article that suggested that R was basically dead, and that Python was the way to go. Is that overstatement?
  • Do you think any of the work that you've done can translate to non-Coursera communities? Specifically ML developers?
  • Do you have a knowledge engineer on your team? How do you know that there is no better ontology for your purposes?
  • How important is understanding the business domain for data scientists? How much knowledge data scientist have related to business analysis to identify and work on different business problems?
  • How many tags do you have? What does the classifier that predicts them look like? What metrics do you use to assess them?
  • Have you ever looked at trying to analyse the learning style of learners ie preference to reading/videos/quizzes/assignments. Could identifying ratio of reading to videos to quizzes to assignments etc. help with recommendations?
These are awesome questions! Keep the conversation going by sharing your thoughts on these questions below – and feel free to share new questions, too.
