  • Patent number: 6751601
    Abstract: The invention consists of a learning system (108) based on the Dynamical System Architecture (DSA). Every implementation of the DSA is composed of a dynamic system (112) and a static system (116). The dynamic system (112) generates an intermediate output (114), which together with an external input (100) is fed into the static system (116), which produces a generated output (106). Every time the dynamic system (112) is reset it produces the same trajectory: an intermediate output (114) that does not cross over itself during the temporal span of each of the events generated by a reference system (102) whose behavior has to be duplicated. The static system (116) can be anything that behaves like a trainable universal function approximator. Training uses the intermediate output (114), the external input (100), the observed output (104) produced by the reference system (102) whose behavior is going to be mimicked, and a self-organizing procedure that only modifies the parameters of the static system (116).

  • Patent number: 6745169
    Abstract: A learning process for a neural network for open-loop or closed-loop control of an industrial process with time-variable parameters. The neural network is configured either as an open-loop or closed-loop-control network with which the process is controlled. The neural network is trained with the current process data so that it builds a model of the current process. The neural network can also be configured as a background network which is trained during operation with representative process data so that it builds an averaged model of the process over a longer period of time. After a certain learning time or upon the occurrence of an external event, the open-loop or closed-control network is replaced by the background network.

  • Patent number: 6741973
    Abstract: A model of consumer behavior in a transaction environment such as customers moving around a bank branch, is generated from an artificial life algorithm to create a number of agents. In each agent, a genetically encoded drive, equivalent for example to hunger, is defined so as to correspond to a transaction need such as the need for cash. Interaction rules, such as navigation rules, are set for interaction between the agents and a first representation of an environment, and the program is run and the agents observed, then compared with real human behavior. The best matched agents are selected and the program run again, the steps being repeated until a required level of comparison with real behavior is reached. The model can then be used with different transaction environments to study customer behavior and to select the best branch layout or the like.

  • Patent number: 6741975
    Abstract: An expert system and a method of providing automated advice are described. The system is regularly updated by advice (or diagnosis, recommendation etc.) given by practitioners in the relevant field. The combination of the underlying facts and the consequent (human) advice is used to update a ruleset that is then used to provide automated advice. An example of financial advice is given. A database contains the details for the customers of a financial institution together with advice and recommendations given previously by the institution's human advisors. This database is used to derive a ruleset which is then applied to a subsequent customer's details in an automated manner, possibly at the user's own PC via the World Wide Web. Frequent updating using data from the human advisors' work means that the database (and hence the ruleset) are kept up to date. Consistent advice can thus be provided with minimum human interaction.

  • Patent number: 6725209
    Abstract: A system and method for providing computerized, knowledge-based medical diagnostic and treatment advice. The medical advice is provided to the general public over a telephone network. Two new authoring languages, interactive voice response and speech recognition are used to enable expert and general practitioner knowledge to be encoded for access by the public. “Meta” functions for time-density analysis of a number of factors regarding the number of medical complaints per unit of time are an integral part of the system. A semantic discrepancy evaluator routine along with a mental status examination are used to detect the consciousness level of a user of the system. A re-enter feature monitors the user's changing condition over time. A symptom severity analysis helps to respond to the changing conditions. System sensitivity factors may be changed at a global level or other levels to adjust the system advice as necessary.

  • Patent number: 6721718
    Abstract: A reduced control system suitable for control of a nonlinear or unstable plant is described. The reduced control system is configured to use a reduced sensor set for controlling the plant without significant loss of control quality (accuracy) as compared to an optimal control system with an optimum sensor set. The control system calculates the information content provided by the reduced sensor set as compared to the information content provided by the optimum set. The control system also calculates the difference between the entropy production rate of the plant and the entropy production rate of the controller. A genetic optimizer is used to tune a fuzzy neural network in the reduced controller. A fitness function for the genetic optimizer provides optimum control accuracy in the reduced control system by minimizing the difference in entropy production while maximizing the sensor information content.

  • Patent number: 6714923
    Abstract: A system and method which allow genetic algorithms to more accurately parallel a biological genetic paradigm by employing synthetic genes. Genotypical synthetic chromosomes are recursively expanded to produce a population of phenotypical state models, bit strings or other forms of encoding that suitably represent a particular problem set. Sexual-like recombination takes place at the synthetic chromosome level, using synthetic genes, whereas fitness evaluation and selection take place at the level of the fully developed, i.e. expanded, and encoded structure. Additionally, a system and method are also taught for encoding complex data structures into synthetic genes as well as a system and method for non-replicative information data set encryption utilizing synthetic genes wherein information extraneous to the data set, such as encryption keys, may be embedded within the synthetic gene structure.

  • Patent number: 6708159
    Abstract: A finite state electrical automaton modeled after a human neuron comprises a plurality of weighted inputs that pass into a state computing unit. A feedback mechanism changes the weights of the inputs as needed to control the response of the automaton to a desired output. A clock signal allows the automaton to function as a discrete time system. Unlike the threshold gates, the present automaton is capable of outputting an n-bit digital value analogous to a cell membrane potential. Because this automaton is capable of outputting more than two simple states it is a better building block for building neural nets.
