1. Functions

The Front End

  1. Gathers various types of Health Data through it sensors,
  2. Processes Health Data, produces AIH Data, and updates its Neural Network Model.
  3. Entrusts AIH Data to the Back End together with Licence Data.
  4. May discover that there may be risks in the AIH Data and send Anomaly and Risk Alert to the Back End.
  5. May be requested to send its trained NN Model to the Backend for Federated Learning.
