  • Patent number: 7020644
    Abstract: A Collection Knowledge System provides context-sensitive knowledge delivery services to application programs, thereby enabling application programs to effectively support variant computational processes. In operation, a Collection Knowledge System receives knowledge requests from application programs, performs local and remote lookups into structured trees of knowledge, and returns requested knowledge to requesting application programs. Collection Knowledge Systems can manage knowledge for entire variant computational processes, thereby enabling application programs to calculate and execute many variant computational processes in fully automated, scalable ways that were not previously possible. As a consequence of automated process construction and execution, associated human labor costs are effectively reduced to zero.

  • Patent number: 6965812
    Abstract: A robotic system which controls the movement of a surgical instrument in response to voice commands from the user. The robotic system has a computer controlled arm that holds the surgical instrument. The user provides voice commands to the computer through a microphone. The computer contains a phrase recognizer that matches the user' speech with words stored in the computer. Matched words are then processed to determine whether the user has spoken a robot command. If the user has spoken a recognized robot command the computer will move the robotic arm in accordance with the command.

  • Patent number: 6922680
    Abstract: A method and apparatus are disclosed for recommending items of interest by fusing a plurality of recommendation scores from individual recommendation tools using one or more Radial Basis Function neural networks. The Radial Basis Function neural networks include N inputs and at least one output, interconnected by a plurality of hidden units in a hidden layer. A unique neural network can be used for each user, or a neural network can be shared by a plurality of users, such as a set of users having similar characteristics. A neural network training process initially trains each Radial Basis Function neural network using data from a training data set. A neural network cross-validation process selects the Radial Basis Function neural network that performs best on the cross-validation data set. A neural network program recommendation process uses the selected neural network(s) to recommend items of interest to a user.

  • Patent number: 6865563
    Abstract: The Neuron network modeling compares neuron behavior in terms of electrical properties to predict the propagation of capacitative, or inductive current/potential along a nerve fiber.

  • Patent number: 6850921
    Abstract: A method (100) for cascading system level target to component level design objectives using machine learning and design synthesis techniques. The method (100) of the present invention uses machine learning techniques to build (106, 108) surrogate models from given system targets (102). The method then employs design synthesis methods to determine (110) a range of component level design objectives for the given system level targets using the surrogate models. The range of component level design objectives is fed back (112) to one of the surrogate models to determine (114) the component design objectives.

  • Patent number: 6842745
    Abstract: A chaotic signal generator includes a set of elements connected together for generating chaotic signals. The connection scheme may correspond to the circuit generally referred to as Chua's circuit, particularly when implemented as a cellular neural network. Interposed in the connection scheme is at least one switch, such as a MOS transistor. Opening and closing of the switch causes variation in the chaotic dynamics of the generated signals. A command signal applied to the switch may correspond to a modulating signal for transmission on a channel, such as a high noise channel. The modulating signal may be a binary signal, and the command signal may be a switching signal having a frequency that increases or decreases depending on the logic level of the binary signal.

  • Patent number: 6834274
    Abstract: A knowledge management database system and method for building such a system relies on input from various subject matter experts to review and validate the structure of the database (in terms of substantive subject matter areas included in the database, their definitions, focus) and the various items stored in the database. The review and validation renders the database as “easy to use” by a novice in the particular situation, allowing that user to easily navigate through the database system and find a response to a particular issue or problem. Such a database management system is particularly useful in a large organization, or one with rapid turnover in certain jobs, allowing a user who may be unfamiliar with various aspects of a particular issue to readily find the relevant information.

  • Patent number: 6823322
    Abstract: A nonlinear signal mapper that can implement any continuous one-to-one nonlinear map of baseband or intermediate-frequency digital signals. The mapping method follows a “divide-and-conquer” approach in that a nonlinear map to be implemented is piecewise decomposed into a set of simpler nonlinear component maps. The component maps are implemented using code-enabled feed-forward neural networks (FF-NNs). Each code-enabled feed-forward neural network only operates on samples of a digital input signal that lie in a specified interval of the real-valued number line. Code-enabled FF-NNs are controlled by codewords produced by a scalar quantization encoder. The quantization encoder also controls a multiplexer that directs values produced by the FF-NNs to the nonlinear mapper's output.

  • Patent number: 6820070
    Abstract: In an automatic decision-making system, a method and a tool for the reduction of the dimension of data mining, which is automatically coupled to an empirical predictor of the system. The method includes a qualitative modeling of the interrelations between various objects whose attributes are relevant to a score made by the predictor according to which decisions are made, wherein this relevancy is determined by an input of a domain expert to the problem in hand. The model is called a Knowledge-Tree and its conclusions are represented by a graphical symbolization called the Knowledge-Tree map. Data mining, which follows the construction of the Knowledge-Tree map regards only datasets which are associated with logical and validated branches of the knowledge tree. Because the expert input which reduces the dimension of data mining was completed prior to data mining, interception by human reasoning is not needed after data mining and the decision making process can proceed automatically.

  • Patent number: 6807535
    Abstract: A computer implemented method and apparatus for simulating an intelligent tutor for interactive adaptive training of learners in any domain includes a Domain Module, a Tutor Module and an Interface. Items to be learned, and their prerequisite and other dependency relationships are represented in a fuzzy graph, together with a fuzzy logic computational engine, which dynamically adapts the available sequence of training actions (such as presentations/explanations, simulations, exercises and tasks/questions) to a current assessment of the learner's knowledge skill, the level of difficulty of the presented material, and preferences and learning style of the individual learner. Fuzzy logic is used as the basis of arc weightings, and the computations, but the general methodology is applicable to other approaches to weighting in computation.

  • Patent number: 6804661
    Abstract: A method for assessing a condition of an organism having body waves corresponding to states of the organism. The method includes the step of recording signals corresponding to a body wave, output by a portion of the organism in a first state, to provide a first record. In a similar manner, signals are recorded during a time period in which the organism is in a second state, to provide a second record. The first and second records, are processed by applying feature expansion procedures thereto. The results of the feature expansion procedures are evaluated to identify first selected feature expansion procedures effective to distinguish values of the first signals corresponding to the first state from values of the first signals corresponding to the second state.
