Federated learning is a machine learning
technique that trains an algorithm across
multiple decentralized edge devices
or servers holding local data samples,
without exchanging them.
It enables multiple entities to
collaboratively train a model while ensuring
that their data remains decentralized.

Each node trains the model to fit the data they have.
Each node sends a copy of its trained model back to the server, and the server
combines these model by taking average and it an iterative process.

CORE CHALLENGES
Expensive Communication.
Systems Heterogeneity: Diversity of devices participating in the training
process can vary in computational power, network connectivity, battery life.
Statistical Heterogeneity: situation where devices participating in the training
process have local datasets that follow different distribution.

Ensuring privacy, since the data remains on the user’s device.
Lower latency, because the updated model can be used to make
predictions on the user’s device.
Smarter models, given the collaborative training process.
Less power consumption, as models are trained on a user’s device.
