Following on from publication of the work by our team here at Coronasurveys and presentation at the KDD 2020 Conference Workshop, August 24, 2020, the head of health at facebook (KX Jin) kindly invited us to take part in the Covid-19 symptom data challenge, which utilises data collected by two streams primarily gathered by facebook questionaries and promotion on the facebook platform.
We are currently preregistered and engaged in preparation of the submission.
