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.
