The Ubex platform will provide ample opportunities not only to publishers and advertisers, but also to companies that need regression analysis of user data. The system’s neural core, which is responsible for making decisions at all stages of the life cycle of the advertising material, will have an API, access to which can be provided to partner companies. The behavioral decision-making blockchain allows one to evaluate user data and make a judgment about the perceived interests of the user. This regression estimate can be used not only to display advertising materials, but for other purposes as well. The API will provide an opportunity to retrieve a list of expected categories with an estimate for each based on a query with user data.
