Associative Recall

An architecture is presented here which can be used for some important paradigms of intelligent systems. This architecture targets applications which require real time processing of stream inputs with versatile hardware which exploits parallelism. The architecture is particularly suited for pattern recognition paradigms which are based on the use of decision trees. Artificially intelligent systems based on decision trees interestingly present some common computational requirements which can be served very efficiently by a Data Flow architecture. A small set of different functions is computed repeatedly with simple result tokens passed from one computation to successive ones. Developments in optical processing have introduced elements which are particularly suited to the computational requirements of some of these systems, and therefore they can be effectively employed in this architecture. The architecture presented here is based on Data Flow design principles and is enhanced with optical processing elements. The function of the architecture is illustrated by discussing the mapping of two specific AI paradigms—a pattern classifier and an associative recall mechanism.

Intensity Contrast

In the formation of an image each small volume element of the object is correlated to an areal element in the image. The structure or detail of the object is represented by changes in intensity from element to element, and this variation of intensity (contrast) is determined by the interaction of the electrons with the specimen, and by the optical processing of the information-carrying electrons. Both conventional and scanning transmission electron microscopes form images which may be considered in this way, but the mechanism of image construction is very different in the two cases. Although the electron-object interaction is the same, the optical treatment differs.
