Principal Components of Natural Images: An Analytical Solution

1993
Abstract : The structure of receptive fields in the visual cortex is believed to be shaped by unsupervised learning. A simple variant of unsupervised learning is the extraction of principal components. In this paper, we derived analytically the form of the principal components of natural images.

Exact Solutions for Recursive Principal Components Analysis of Sequences and Trees

2006
We show how a family of exact solutions to the Recursive Principal Components Analysis learning problem can be computed for sequences and tree structured inputs. These solutions are derived from eigenanalysis of extended vectorial representations of the input structures and substructures.
