  • Publication number: 20140173096
    Abstract: The requirement to record interactions by organizations is growing, driven by the need to improve the quality of customer interactions in combination with regulatory and fraud protection requirements. The necessity to provide resiliency as well as flexibility to have multiple copies of a recorded interaction is leading many organizations to investigate mechanisms to create multiple recordings of interactions from a single source. The purpose of this invention is to enable this capability on a standards compliant interaction recording source.

  • Patent number: 8301576
    Abstract: A method of training a neural net includes receiving a plurality of sets of data, each set representative of a plurality of inputs to the neural net and a resulting at least one output from the neural net and calculating a plurality of network weights for the neural network based on the received plurality of sets of data. Calculating the plurality of network weights including attributing greater weight in the calculation to at least one set of the plurality of sets of data than at least one other set of the plurality of sets of data.

  • Patent number: 7777743
    Abstract: A method for hierarchical visualization of multi-dimensional data is provided. A first dimension-reduction process is applied to a multi-dimensional data set to obtain a first visualization. A subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization is selected. A second dimension-reduction process is applied to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.

  • Patent number: 7716148
    Abstract: An apparatus and method for processing mixed data for a selected task is provided. An input transformation module converts mixed data into converted data. A functional mapping module processes the converted data to provide a functional output for the selected task. The selected task may be one or a combination of a variety of possible tasks, including search, recall, prediction, classification, etc. For example, the selected task may be for data mining, database search, targeted marketing, computer virus detection, etc.

  • Publication number: 20090055411
    Abstract: A system and method for handling duration values includes associating a duration value with a start datetime to allow precise duration handling. Thus, a uniform time line approach may be used to handle duration arithmetic, comparisons, or other computations for duration values. For example, the uniform time line approach may characterize a duration value as a difference between two endpoints of a timeline segment having a length equal to the duration value. As a result, duration operations can be carried out with precision and accuracy using simple calendar calculations.

  • Patent number: 7444310
    Abstract: A model maintenance method is provided. If accuracy of prediction by a current model through consultation with new data is determined to be below a predetermined threshold, a compound model is formed by supplementing the current model with a local net trained with the new data.

  • Patent number: 7298906
    Abstract: A method for feature selection based on hierarchical local-region analysis of feature characteristics in a data set of mixed data type is provided. A data space associated with a mixed-type data set is partitioned into a hierarchy of plural local regions. A relationship metric (for example, a similarity correlation metric) is used to evaluate for each local region a relationship measure between input features and a target. One or more relevant features is identified, by using the relationship measure for each local region.

  • Publication number: 20060224532
    Abstract: Systems, methodologies, media, and other embodiments associated with feature weighting in neural networks are described. One exemplary method embodiment includes using a set of weights to scale input feature values. Then the scaled data are used to train a neural net model of the relationship to be learned. The learned model is used to produce a new set of feature weights. The procedure continues iteratively until stopping criteria is met.

  • Patent number: 7092922
    Abstract: An adaptive learning method for automated maintenance of a neural net model is provided. The neural net model is trained with an initial set of training data. Partial products of the trained model are stored. When new training data are available, the trained model is updated by using the stored partial products and the new training data to compute weights for the updated model.

  • Publication number: 20050159994
    Abstract: A method for plan generation is provided. One or more initial plans are generated and evaluated to determine quality scores for the plans. One or more of the plans is selected according to the quality scores and modified to generate modified plans. The modified plans are evaluated to determine updated quality scores for the modified plans. Selection, modification and evaluation of modified plans are repeated until one of the modified plans is satisfactory.
