Cognition Perspective: The Manifold Ways of Perception.

H. Sebastian Seung & Daniel D. Lee.
Science v.290 no.5500, Dec.22, 2000. pp.2268--2269.

One of the great puzzles of visual perception is how an image that is
in perpetual flux can still be seen by the observer as the same
object. In an informative Perspective, Seung and Lee explain the
mathematical intricacies of two new algorithms for modeling the
variability of perceptual stimuli and other types of high-dimensional
data (Tenenbaum et al., and Roweis and Saul).
