I found the follwing (below) PDFs and was wondering what I need to know (other than Linear Algebra and Probability) before reading them.
Usually when I need to quicky learn about a subject I go to Amazon and check out the TOC of relevant books, but in this case High Dimensional Geo turns up nothing. Is it a subset of (possibly more general) subject? Does this subject possibly go by any other names?
