  • 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.

  • Patent number: 6704719
    Abstract: An apparatus, computer-readable medium and method for use in association with case-based reasoning and the like utilize a novel decision tree data structure that incorporates a search criterion in association with each test answer to a test criterion defined within a decision node, for use in selecting cases from a search space that match the associated test answer to the test criterion. As such, rather than storing identifiers to the actual cases in a case library, or search space, within a decision tree data structure, search criteria are used to provide the mechanism by which those cases that represent most likely best matches can be dynamically selected.

  • Patent number: 6697789
    Abstract: The computer system includes a receptor field (2) with sensors (Ri) each of which receives data with specific characteristic (A, B, C). These data are passed to processors (Pi, Pi/k), whereby only those connections (Li) between sensors and processors are released that are suited to an evaluation of the data according to a combination of specific data dictated by a phase program of a phase program circuit (7). The computer system also includes a selector circuit (71) that discards those program commands from dictated program commands (73) that lead to a “senseless” computation result. A motor program circuit (8) for the control of effectors (9) may be connected to the computer system that at least contribute to the movement of the receptor field (2) in order to bring the receptor field closer to suitable data with specific characteristics in order to enable better execution of the program.

  • Patent number: 6697791
    Abstract: A technique is provided for systematically constructing one or more correlation rules for use by an event management system for managing a network with one or more computing devices. The technique comprises the following steps. First, in association with an event cache, event data representing past or historical events associated with the network of computing devices being managed by the event management system is obtained. Next, a first pattern is found or detected in the obtained event data associated with the event cache. The pattern is then classified. Then, at least one correlation rule is constructed based on the classified pattern. Lastly, in association with the event cache, the one or more events included in the pattern are replaced with a composite or cumulative event such that hierarchical patterns may be subsequently found for use in constructing further correlation rules.

  • Patent number: 6681215
    Abstract: A system and method for improving a causal network is provided. A new apriori probability is determined for a repair or a configuration factor within the causal network and compared to an old apriori probability. If the new apriori probability differs from the old apriori probability by more than a predetermined amount, the causal network is updated. Further, in another aspect, a causal network result is stored for a causal network, wherein the causal network includes a plurality of root causes with a symptom being associated with each of said root causes. An existing link probability is related to the symptom and root cause. An expert result or an actual data result related to each of the symptoms is stored. A new link probability is computed based on the stored causal network result, and expert result or the actual data result.

  • Patent number: 6662169
    Abstract: In a computer system functioning as an autonomous agent with a robotic controller wherein the computer system need not be programmed to perform a specific task, values in an array of error variables are obtained from comparison between an array of resources variables used to indicate resource use and state of an Autonomous Agent and an array of corresponding desired levels for the resource variables. Each individual value in the array of error variables represents an error in the actual value of a particular resource variable as compared to its desired value. Derivative variables for the resource variables and for parameters controlling behavior of the Autonomous Agent are created. The values of the array of error variables and their associated derivative variables are used to adjust values of the behavior-controlling parameters thereby modifying behavior of the Autonomous Agent.

  • Patent number: 6658395
    Abstract: A system and method for enhancing knowledge discovery from data using multiple learning machines in general and multiple support vector machines in particular. Training data for a learning machine is pre-processed in order to add meaning thereto. Pre-processing data may involve transforming the data points and/or expanding the data points. By adding meaning to the data, the learning machine is provided with a greater amount of information for processing. With regard to support vector machines in particular, the greater the amount of information that is processed, the better generalizations about the data that may be derived. Multiple support vector machines, each comprising distinct kernels, are trained with the pre-processed training data and are tested with test data that is pre-processed in the same manner. The test outputs from multiple support vector machines are compared in order to determine which of the test outputs if any represents a optimal solution.
