A Wholistic Cognitive System (Seer-2) for Integrated Perception, Action and Thought

Leonard Uhr

This papcr describes a computer-gramned model, SEER-2, that can perform a variety of different types of actions that span the hman intellectual processes, including naming objects, describing scams, answering simple questions, deducing solutions to simple problems, pointing to objects, and manipulating objects. Recognition, description, memory search, and deduction are all handled in the ssme semantic cognitive network, using the same basic type of general transformation. Thus they are all intermingled, and can conveniently interact and call upon one another, as needed. SEER-2's acts, hoth external and internal, are a function of a variety of influences, including the presses of internal needs and of external objects, as well as verbal commands (that is, the understood import of verbal utterances). SEER-2 is thus a first step toward an integrated wholistic ccgnitive system, one that is as simple and general as possible yet begins to handle a representative variety of cognitive processes. The SEER system uses a set of transforms that compose its memory network, and contin the specific information needed to handle the typcs of problems it will encounter - much as a parser must bc given a set of rewrite rules that contain the needed information about the vocabulary and grammar of the languages to be parsed. In future systems he will attempt to have these memory transforms learned through experience. But for now they must be given the system. Examples of SEER-2's behavior when given a sma11 memory are presented.
