As clever as learning computers may be, they only have as much potential as their software. What if you don't have the know-how to program one of these smart systems yourself? That's where Microsoft Research thinks it can help: it's developing a machine teaching tool that will let most anyone show computers how to learn. So long as you're knowledgeable about your field, you'd just have to plug in the right parameters. A chef could tell a computer how to create tasty recipes, for example, while a doctor could get software to sift through medical records and find data relevant to a new patient.
