What unsupervised learning is and how it differs from supervised

For each upcoming mini project, write the question you want answered without a target and what a useful answer looks like. Concepts: No target; discovering structure; similarity, distance, density, latent structure; human validation Project A: Project A in each topic = a business-facing dataset (customers, transactions, baskets). Project B: Project B in each topic = a contrasting dataset (time profiles, images, sensor-style series) so you see the same technique behave differently.
