  1. Problem:
    How to visualize high-dimensional data

  2. Solution:
    giving each datapoint a location in a two or three-dimensional map

  3. Advantage:
    a. easier to optimize than other existing techniques
    b. could reduce the tendency to crowd points together in the center of the map
    c. could create a single map that reveals structure at many different scales
    d. could use random walks on neighborhood graphs to allow the implicit structure of all of the data to influence the way in which a subset of the data is displayed
