A feature discovery heuristic

Search for patterns localized in space and/or time.  Temporal localization can be accomplished using the temporal sequence heirarchy built into Asa H (see my Trans. of the Kansas Academy of Science 2006 paper on Asa H). Temporal patterns are of various durations; i.e., of various scales.  Higher levels in the hierarchy record longer duration patterns. Spatial localization can be accomplished by deviding the visual field into a grid of cells.  Each cell contains a set of points in 2-D.  Patterns are learned over the points in each of these cells.  The cells can be overlapped and cells can be of various different sizes.
