PD digital biomarker participants: It has been a long time coming - scoring for Sub-challenge 2 is now open. Please find instructions in the wiki and templates and scoring code in the scoring resources folder. Also, to give you enough time to test your submissions we are extending the deadline for submission until 10-November 5pm Pacific time (8pm ET). In scoring submissions we will only evaluate the features that you include in your uploaded files. This means that you should include any metadata along with features derived from the accelerometer data that you find valuable. Baseline models (just including metadata: device, session, site, task, visit and deviceSide) do pretty well and you will have to beat these baseline models in your submissions. We are also finalizing the scoring and reviews of write-ups for sub-challenge 1 and will notify some of you early next week about nominations for travel awards to the DREAM conference. We look forward to receiving your solutions. Good luck participants! The Parkinson's Disease Digital Biomarker DREAM Challenge Organizers
