Abstract: Short-term forecasts of COVID-19 spread have been used for planning intervention strategies and resource allocation. Observed patterns of cases, deaths, and hospitalizations, as well as measurements of human interaction through proxies such as social connectedness or population movement have proved useful for predictive modeling of COVID-19. Using these measurements, I draw parallels between spatial statistical models and machine learning for capturing spatiotemporal dependence in the context of epidemiological data, and compare the power of Facebook’s social connectedness with cell phone-derived human mobility metrics for predicting new cases and hospitalizations of COVID-19. I then present evaluations of our machine learning-based spatiotemporal models for forecasting county-level cases and state-level hospitalizations of COVID-19 in the US, which are contributed to national reports on a weekly basis. Evaluations show considerable improvement in two- to four-week prediction horizons over baselines. I will conclude with a discussion on the practicality, requirements, advantages, and disadvantages of using machine learning for forecasting the spread of infectious diseases, as well as opportunities for improving disease forecast and modeling.
