The Health Federated Learning (AIH‑HFL) AIM integrates into a new NN Model the knowledge acquired by trained NN Models participating in the Federated Learning process:
| Receives | Federated Learn Response | Response to Federated Learning Request containing the trained NN Model. |
| Produces | NN Model | NN Model submitted to MPAI Store. |
| Federated Learn Request | Request to Health Front End for a given NN Model. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for the Health Federated Learning (AIH‑HFL) AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present, and conform with the Qualifier, if present.
| Receives | Federated Learn Response | Shall validate against Federated Learn schema. |
| Produces | NN Model | Shall validate against ML Model Object schema. |
| Federated Learn Request | Shall validate against Federated Learn schema. |
