This paper presents results related to a new design approach dedicated to cognitive system strategies. The scenario concerning a robot integrated in a cognitive system is described. The paper focuses on the development of a pattern of human knowledge and on a new data structure which are able to organize and manipulate the involved information. The definitions of signatures and of signature classes are given as one of the first steps in an alternative modeling approach to the observation process. The paper ends with an example that deals with using the signatures in the observation.
I INTRODUCTIONThe pattern of human knowledge analyzed here represents a step that belongs to a large project dedicated to new cognition systems based on the experimentation of the causal relations. The big challenge regarding the studies on human cognition is to answer the question on how can human mind obtain synthesis from experimental data. This deals in fact with how the human mind can build veridical models of reality only from, apparently, disturbed and unsubstantial data [1], the only information we can get through our senses.The domain under investigation requires the solving of this problem as an interdisciplinary one. Two aspects are investigated in this context, the psychological and the technical one. The psychological approach, known as Cognitive Psychology (CP), has in view, as an objective, the understanding of the human knowledge phenomenon, the obtaining of models of the processes which occur during this phenomenon. The technical approach, referred to as Machine Learning, Robotics and Artificial Intelligence (AI), aims to build a mathematical model and then to design and achieve a product.From the technical point of view, according to EU's IST 2002 23.24 a cognitive system is a system that understands, learns and develops itself by social and individual interactions [2]. The desired objectives are based on the achievements referring to the three components of a cognitive system: the action which is external (the robot control) [3] and internal [4] (the approaching of a behavior through which the system focuses on a certain problem); the perception, which suppose the interpreting of the signals obtained from the sensorial system and the using of this interpretation in describing a situation that triggers the reasoning; the reasoning which is the one that co-ordinates the action and the perception. According to [3], the reasoning is conducted in terms of two functions, symbolizing and manipulating the symbols.The following requirements are pointed out regarding the limitations of the domain and the less approached directions (because of the novelty of the domain):-Up to now the research focused on the organizing of the cognitive system. We consider in [24] that the auto-organizing of the knowledge process can be obtained by knowledge process itself. The mentioned process is controlled by a certain structure of knowledge which is modified because of the new knowledge. We consider that the mentioned dynamics can be known ...
