Ted Dunning: An Introduction to Polyvalent Recommendation

May 16, 2013 · 7:00 PM
Netflix

Speaker: Ted Dunning, Chief Application Architect at Mapr and Co-author of Mahout in Action

Topic: A new approach to recommendation, polyvalent recommendation, that is both simpler and much more powerful than traditional approaches. The idea is that you can combine user, item and content recommendations into a single query that you can implement using a very simple architecture.

is sorry to have missed it. I missed meeting Ted and Paul O'Rorke, a former Sony Data and Statems Architect I just missed working with.

As far as "Learning ot rank in a very bayesian way", I admit to being leery of a method of ranking that "...present(s) comments to a user, the metric would be sampled independently for each comment and the comments would be sorted according to the resulting scores."

http://papers.ssrn.com/sol3/papers.cfm?abstract_id=955984

...why not present negatively rated comments with some threshold-override frequency just to make sure that the already over-self-sampling of a highly opinionated group doesn't self-reinforce to the point that it never even gets the chance to read an oppostional or alternative viewpoint!

Exposure to only that content some algorithm decides you will agree with, "a priori", can be a potential "social danger", eh? ;^D

This is an outstanding group - very friendly, great questions, good interactions. I look forward to seeing how it evolves with each new event.

Thanks again to Netflix for providing the excellent meeting space and food, and to Will and Joel for organizing the event. Enjoyed meeting some new people tonight.

For those interested in more from Ted, here's a recent blog post on a new approach to ranking with Bayesian bandits: "Surprise and Coincidence" http://bit.ly/13xwQIX

Cheers, Ellen
