IBM Federated Learning

Federated Learning provides the tools for training a model collaboratively, using a federated set of secure data sources. The data sources are never moved or combined, but they each contribute to training and improving the quality of the common model.

Tech preview notice

This is a technology preview and is not supported for use in production environments.

Federated Learning is appropriate for any situation where parties want to leverage their data without sharing their data. For example, an aviation alliance might want to model how a global pandemic impacts airline delays. Each participating party in the federation can use their data to train a common model without ever moving or sharing their data, thus preserving data privacy and security and improves pragmatics. The resulting model can be deployed to provide more accurate predictions for scoring data to give each member of the alliance better results and insights.

This illustration shows how federated parties send data to train the common model without sharing data with each other. The aggregator manages updates to the model.

Federated Learning concept overview
Figure 1: Given the query (Q), each party computes a reply (R) based on their own local data (D) which they send back to the aggregator, where results fuse together as a single Federated Learning model (F).

Federated Learning provides the means to:

When to use Federated Learning

Federated Learning allows secure model training for large enterprises when the training uses heterogenous data from different sources. The focus is to enable sites with large volumes of data with different format, quality and constraints to be collected, cleaned and trained on an enterprise scale. Another key feature is that Federated Learning also allows you to train large datasets without having to transfer that data to a centralized location, which reduces data privacy risk and computational complexity.
