Apps

PrimeHub aims at being a MLOps platform where scientists can orchestrate data/tools for the acceleration of researches. In terms of a platform, we introduce PrimeHub Apps that PrimeHub capability is able to be extended by integrations of 3rd-party applications such as auto ML tools, visualization tools, etc. These integrated applications also benefit from access-control and resource constraints of PrimeHub.
