There are multiple use cases. In the world of medicine, there are projects, like Neuron, that have developed several interesting products in beta. These products will guide and teach users how to train their decentralized AI; in other words, how to train the trainer. Users will be able to see how to construct datasets of their health, and where and how to access these datasets. One product uses AI and ML to automatically fill in your physical statistics on the app just by taking a selfie. The Selfie2BMI module uses state-of-the-art Deep Neural Networks and optimization techniques to predict a variety of anatomic features including height, weight, BMI, age and gender from a face.
