Thanks to the blockchain technology, you can check the relevance of data and trained models of machine learning. Thus, you create trust in the data and confidence that you have received exactly what you paid for. Our platform allows you to create models of machine learning, as well as combine existing ones, in order to obtain one model that has the functionality of integrated models. The merging of the existing models ones allows to significantly save the funds and time required for development and training in comparison with the development of new models of machine learning.
