Patent number: 6944616Abstract: A system and method for historical database training of a support vector machine (SVM). The SVM is trained with training sets from a stream of process data. The system detects availability of new training data, and constructs a training set from the corresponding input data. Over time, many training sets are presented to the SVM. When multiple presentations are needed to effectively train the SVM, a buffer of training sets is filled and updated as new training data becomes available. Once the buffer is full, a new training set bumps the oldest training set from the buffer. The training sets are presented one or more times each time a new training set is constructed. A historical database of time-stamped data may be used to construct training sets for the SVM. The SVM may be trained retrospectively by searching the historical database and constructing training sets based on the time-stamped data.Type: GrantFiled: November 28, 2001Date of Patent: September 13, 2005Assignee: Pavilion Technologies, Inc.Inventors: Ralph Bruce Ferguson, Eric J.

Patent number: 6941289Abstract: A computer-implemented method and system for building a neural network is disclosed. The neural network predicts at least one target based upon predictor variables defined in a state space. First, an input data set is retrieved that includes the predictor variables and at least one target associated with the predictor variables for each observation. In the state space, a number of points is inserted in the state space based upon the values of the predictor variables. The number of points is less than the number of observations. A statistical measure is determined that describes a relationship between the observations and the inserted points. Weights and activation functions of the neural network are determined using the statistical measure.Type: GrantFiled: April 6, 2001Date of Patent: September 6, 2005Assignee: SAS Institute Inc.Inventors: James Howard Goodnight, Wolfgang Michael Hartmann, John C.

Patent number: 6931383Abstract: Apparatus for adding new learning tasks to an incremental supervised learner provides a flexible incremental representation of all encountered training examples, thereby permitting state representations for new learning tasks to take advantage of incremental training already completed by encoding all past training examples as negative examples for a hypothetical learning task. The state representation of the hypothetical learning task is copied as the initial state representation for a new learning task to be initiated, and is initialized with negative training examples of all previously presented training examples, thereby permitting the learning task to efficiently incorporate the previous examples.Type: GrantFiled: October 21, 2003Date of Patent: August 16, 2005Assignee: AT&T Corp.Inventors: David D. Lewis, Amitabh Kumar Singhal, Daniel L. Stern

Patent number: 6925452Abstract: A method and system are described for end-user transaction recognition based on server data such as sequences of remote procedure calls (RPCs). The method may comprise machine-learning techniques for pattern recognition such as Bayesian classification, feature extraction mechanisms, and a dynamic-programming approach to segmentation of RPC sequences. The method preferably combines information-theoretic and machine-learning approaches. The system preferably includes a learning engine and an operation engine. A learning engine may comprise a data preparation subsystem (feature extraction) and a Bayes Net learning subsystem (model construction). The operation engine may comprise transaction segmentation and transaction classification subsystems.Type: GrantFiled: May 22, 2000Date of Patent: August 2, 2005Assignee: International Business Machines CorporationInventors: Joseph L.

Patent number: 6920439Abstract: A method and a system are presented, which assist classifiers in gathering information in a cost-effective manner by determining which piece of information, if any, to gather next. The system includes an explicit system, an implicit system, a classifier, and a profit module. A feature set is inputted into the explicit system, which uses the feature set to determine tests to perform to gather information useful for classifying the system state. The relative profit of each test performed is determined by the profit module and the profit determined is used to determine which test or tests to select for a particular feature set. The results of the explicit system, which is generally an exhaustive or semi-exhaustive search algorithm, are used to train the implicit system. The implicit system is then able to process decisions much faster than the explicit system when circumstances require time-critical operation.Type: GrantFiled: October 10, 2000Date of Patent: July 19, 2005Assignee: HRL Laboratories, LLCInventor: Bradley C.

Patent number: 6907413Abstract: Power spectrum data is calculated from a digital audio signal D10. A part of power spectrum data is extracted from thus calculated power spectrum data. Classification is made based on the extracted part of power spectrum data. And the digital audio signal D10 is converted by a predicting method that corresponds to the classified class. Thereby, conversion further adapted to the characteristic of the digital audio signal D10 can be performed.Type: GrantFiled: July 31, 2001Date of Patent: June 14, 2005Assignee: Sony CorporationInventors: Tetsujiro Kondo, Masaaki Hattori, Tsutomu Watanabe, Hiroto Kimura
