In this paper, we introduce a prototype of EpiBench which is currently running and accepting submissions for the task of forecasting COVID-19 cases and deaths in the US states and We demonstrate that we can utilize the prototype to develop an ensemble relying on fully automated epidemic forecasts (no human intervention) that reaches human-expert level ensemble currently being used by the CDC.

Many of these methods are based on traditional epidemiological model which rely on simulations or Bayesian inference to simultaneously learn many parameters at a time.

Furthermore, we propose to generate \emph{diverse} model rollouts by non-uniform sampling of the environment states such that the entropy of the model rollouts is maximized.

A critical factor that can hinder accurate long-term forecasts, is the number of unreported/asymptomatic cases.

In particular, we show that changes in model parameters over time can help us quantify how well a state or a country has responded to the epidemic.

More desirable is a high-level language where the domain-specialist simply specifies the workload in terms of high-level operations (e. g., matrix-multiply(A, B)), and the compiler identifies the best implementation fully utilizing the heterogeneous platform.

Safety-aware exploration is another challenge in real systems since certain actions at particular states may result in catastrophic outcomes.

However, such approaches lead to representations comprising mostly "popular", instead of "relevant", entities in the KG.

The performance of prediction models is often based on "abstract metrics" that estimate the model's ability to limit residual errors between the observed and predicted values.
