Runtime step: Heroku spins up our images into lightweight containers called dynos and connects them to ouradd-on services, e.g., a database. One or more dynos constitute our system infrastructure, including requiredroutersto enable intra-dyno communication. ...
the few NaN values usually meansuspension during that time interval. While forhigh-frequency data,NaN values arepervasive, which usuallymeans no transaction during that time interval. To reduce the simulation-to-reality gap considering data efficiency, we provide different solutions for these two cases...
