Semidefinite embedding

Semidefinite embedding is a way to take data that is hard to work with and make it easier to use. For example, if you have a big list of numbers and you want to find patterns or relationships between them, it can be difficult to figure out what those patterns are. Semidefinite embedding is a way to turn this list of numbers into something else, like a picture. When it's a picture, it's easier to see if there are any connections between the numbers and what those connections might be.
