Drawbridge Challenges Scientific Community to Better the Accuracy of Its Cross-Device Consumer Graph

San Mateo, CA, USA – WEBWIRE

Drawbridge announced today that the company has been selected as the sponsor of the official contest for the 2015 IEEE International Conference on Data Mining (ICDM), which challenges participants to develop an accurate method for predicting cross-device ownership. Drawbridge will award contest winners with $10,000 in prize money, as well as an additional $250,000 prize if any submission is able to surpass Drawbridge’s internal precision/recall benchmark. The accuracy of the Drawbridge Connected Consumer Graph™ was recently found by Nielsen to be 97.3% accurate.
“Over the past four years we have built the leading cross-device identity solution that pushes the limits of probabilistic technology, so we know the value of this work,” said Drawbridge CTO Devin Guan, who was also the architect of the Netflix Prize. “Since we never stop learning and value outside perspectives, we’re asking anyone with an interest in data science, machine-learning, and probability modeling to write an algorithm, build a model, and help us raise the bar. This isn’t limited to just data scientists – we’re inviting other technology vendors, internet companies, think-tanks, labs, and scholars to participate. We love the idea of inspiring the community with a tough problem, and I’m looking forward to seeing the creative and scientific solutions to this challenge that this diverse, crowd-sourced group delivers.”
The Drawbridge Cross-Device Connection Challenge tasks participants with connecting anonymous consumer IDs across different digital devices, without using common personally identifiable user information, such as name, email, social handle, or phone number. For the purposes of the competition, Drawbridge has synthesized various behavioral observations associated with anonymous IDs from different devices and digital environments. Participants are asked to provide the likelihood that a set of different IDs from different domains belong to the same user, and at what performance level. Submissions will be evaluated based on their mean F-score, which is commonly used in information retrieval as a means of measuring accuracy using precision and recall.
Participants have until August 24th to enter the Drawbridge Cross-Device Connection Challenge. Winners will receive prize money, as well as the opportunity to write a paper and lead a workshop on their solution as part of the ICDM conference program. Similar contests have previously been held by companies including Netflix, Facebook, Microsoft, Intel, GE, HP, and Yelp to further their data science efforts.
A live leaderboard is available for a real-time view of the top submissions.
