UK’s partners with PSNC to apply AI and block-chain to Cancer Cell Detection, a Cambridge-based artificial intelligence lab building an open-access decentralized machine learning network for smart infrastructure, announced that Poland’s Poznan Supercomputing and Networking Center (PSNC) will be joining its Collective Learning initiative, to help hospitals and research centers worldwide.

This partnership will allow PSNC to use and contribute data to train algorithms that can be used by hospitals and research centers worldwide to identify and detect circulating cancer cells in patients’ blood or tissue biopsies in the upcoming future.

On’s Collective Learning Module, distributed parties can work together to train machine learning models using blockchain technology and AI learning capabilities without sharing the underlying data or trusting any of the individual participants. It was most recently deployed to identify COVID-19 cases using chest X-ray images establishing a clear distinction between COVID-19 versus pneumonia cases. The collective learning protocol successfully distinguished COVID-19 patients from those with pneumonia from different causes with an accuracy of 97%.

“PSNC provides networking to all the clinical university hospitals in Poland. PSNC jointly with the Institute of Bioorganic Chemistry have been conducting many R&D activities to offer added-value services for advanced data analysis and AI in the area of bioinformatics,” said Maria Minaricova of “Combining their reach with the collective learning module will allow researchers to make use of biomedical datasets across Europe, and analyze them remotely, whilst retaining the data within the country of origin. The ultimate goal is to facilitate the use of healthcare data for research to accelerate the development of new therapies for cancer and other diseases, and make it accessible across Europe.”

“Decentralized ledgers (blockchains) have the potential to optimize the process in which we share private data without requiring trust between participants. Paired with artificial intelligence, this can enable more comprehensive understandings of vast amounts of data,” said Krzysztof Kurowski of PSNC. “’s Collective Learning module has created a scenario in which multiple stakeholders (hospitals and research labs) across Europe can build a shared machine learning model without compromising the privacy of their data. This will allow them to share sensitive information in order to further analyze and detect cancer symptoms amongst patients. We look forward to spearheading this research alongside them.”
