Substra

Open source federated learning software

The most proven federated learning software designed for healthcare research

Aggregate models and insights - not data

Substra is a ready-to-use, open source federated learning (FL) software developed by Owkin, now hosted by the Linux Foundation for AI and Data.

Substra enables the training and validation of machine learning models on distributed datasets. It includes a flexible Python interface and a web application to run federated learning training at scale.

Academic research centers and biopharma companies deploy Substra (formerly Owkin Connect) in a wide variety of federated learning settings for clinical research, drug discovery and development.

It all starts with data

A data scientist registers their data on their Substra servers for machine learning model training.

02/04
Compatible with any model

A data scientist registers a model to be trained on Substra.

03/04
Secure model training

A data scientist trains the model, with computation done securely and autonomously through the Substra network.

04/04
Easily monitor and trace results

Everyone can examine and visualise model performance at the end of the training process to select the best option.
