Koina - An open-source, decentralized machine learning model platform

What is Koina?

Koina is an open-source, decentralized machine learning platform designed specifically for proteomics research. Through standardized interfaces and an online model library, the platform allows researchers to easily upload, share, and access machine learning models without needing local deployment to obtain prediction results. The platform automatically recommends the most suitable model, simplifying data analysis workflows and improving the efficiency of peptide identification and post-translational modification analysis. Koina supports version control and private deployment, ensuring experimental reproducibility and data security. Koina lowers the barrier to entry for machine learning and promotes innovation and widespread adoption of proteomics research through community collaboration.
