<p>Custom Vision is organised hierarchically. At the top level, we have a <em>project</em>, which represents the data and model for a specific task. Within a project, we have one or more <em>iterations</em> of the model, built on different sets of training images. Each iteration in a project is independent: you can create (train) an iteration, deploy it, and delete it without affecting other iterations.
