2. Federated learning trains a shared model by sending model updates, not raw data. It lets diverse data help the model while keeping privacy.

   What NVIDIA says (1)

   “Federated learning is a way to develop and validate AI models from diverse data sources while mitigating the risk of compromising data security or privacy, as the data never leaves individual sites.”
