Answering many of the questions in the field of cancer informatics (and in health care in general), often requires researchers to incorporate data from different sources. Typically, this is done by centralizing the data. In other words, data are brought to the where the algorithms are. Unfortunately, this brings several organizational, operational, political, and ethical challenges, such as loss of data control, logistics of data transmission, data governance, and protection of patient privacy.
Federated learning has emerged as a technology with the potential to overcome these limitations. In this case, we flip things around and we bring the algorithms to where the data are. For this purpose, at IKNL we have developed our open-source priVAcy preserviNg federaTed leArninG infrastructurE for Secure Insight eXchange – or VANTAGE6 for short.
