Catalunya es prepara per al futur postquàntic. 🔐Crearem una anella quàntica pionera a Europa per protegir dades i serveis públics estratègics. 🛡️ 10 M€ per garantir comunicacions segures i anticipar-nos a les noves amenaces digitals. El país ha de liderar aquesta nova revolució tecnològica. Ens hi juguem el futur. govern.cat/salapremsa/notes-…

During a pandemic such as COVID19, we hope (but fail) to accurately estimate the incidence of the disease. In this paper, we propose a new approach to machine-learn models of the real incidence from readily available information (tests and detected cases) journals.plos.org/ploscompbi…

Machine learning mathematical models for incidence estimation during pandemics

Author summary In pandemic situations, adopting timely, effective preventive measures requires accurate and real-time estimates of the incidence of the disease. However, estimates of incidence are...
