Online controlled experiments at large scale
2013
Proceedings of the 19th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '13
Preserved Fulltext
Running experiments at large scale requires addressing multiple challenges in three areas: cultural/organizational, engineering, and trustworthiness. ...
At Microsoft's Bing, the use of controlled experiments has grown exponentially over time, with over 200 concurrent experiments now running on any given day. ...
We have been fortunate to have been part of Bing during the massive growth in experimentation, and wish to thank many people for encouraging data-driven decision making, especially Qi Lu and Harry Shum ...
