I am using the classification learner app. My data is clusters of x,y,z points. My goal is to train the model to say whether the shape that these points make is what I defined as shape '0' or '1'. How do I load multiple, but separate datasets? That is, in each experiment I generate points that make up shape '0' or '1'. Now I want to take several experiments, and load to the classification learner. Obviously I need the learner to know that each experiment is by itself, so it can collect the shapes from each experiment.
