Introducing Substra, a Federated Learning Framework

This covers Federated Learning technology, which addresses the data silo problem that arises in fields such as healthcare where data privacy and security are critical.

Federated Learning is a distributed machine learning approach in which, instead of collecting data on a central server, each data source trains a model on its own local server and only the model weights are transmitted. This approach protects the original data while still making use of data from various sources, which is effective for improving a model's generalization performance and reducing data bias.

Substra is an open-source federated learning framework designed for real-world production environments, and it has already proven its usefulness in complex security and IT infrastructure environments such as medical research.

Hugging Face, in collaboration with Substra, provides a Hugging Face Space where users can understand the principles of federated learning and directly observe how a model responds to changes in data distribution.
