Patent number: 6029157Abstract: A sequence of measured quantities is determined for a chemical reactor and a data generator generates a curve in normal coordinates from a respective predetermined normal form that describes a type of critical state. Each normal form is imaged onto the sequence of measured quantities by neural networks whereby a respective neural network is allocated to a data generator. The imaging is optimized by applying parameter optimization methods. The neural network that converges best through use of parameter optimization method describes the critical state that lies closest to the actual state of the chemical reactor.Type: GrantFiled: August 2, 1996Date of Patent: February 22, 2000Assignee: Siemens AktiengesellschaftInventor: Oliver Mihatsch

Patent number: 6009418Abstract: A semantic attractor memory uses an evolving neural network architecture and learning rules derived from the study of human language acquisition and change to store, process and retrieve information. The architecture is based on multiple layer channels, with random connections from one layer to the next. One or more layers are devoted to processing input information. At least one processing layer is provided. One or more layers are devoted to processing outputs and feedback is provided from the outputs back to the processing layer or layers. Inputs from parallel channels are also provided to the one or more processing layers.

Patent number: 5987445Abstract: A delta learning system takes as an initial fault hierarchy (KB.sub.0) and a set of annotated session transcripts, and is given a specified set of revision operators where each operator within a group maps a fault hierarchy (KB) to a slightly different or revised fault hierarchy (.theta..sub.i (KB)). The revised fault hierarchy (.theta..sub.i (KB)) is called a neighbor of the fault hierarchy (KB), and a set of all neighbors (N(KB)) is considered the fault hierarchy neighborhood. The system uses the revision operators to hill climb from the initial fault hierarchy (KB.sub.0), through successive hierarchies (KB.sub.1 . . . KB.sub.m), with successively higher empirical accuracies over the annotated session transcripts. The final hierarchy (KB.sub.m), is a local optimum in the space defined by the revision operators. At each stage, to go from a fault hierarchy (KB.sub.i) to its neighbor (KN.sub.i+1), the accuracy of the fault hierarchy (KB.sub.Type: GrantFiled: January 5, 1996Date of Patent: November 16, 1999Assignee: Siemens Corporate Research, Inc.Inventors: R.

Patent number: 5963931Abstract: A system for assisting a user in making decisions on a task through the asking of questions about the task and providing answer choices to the questions for the user. The system includes a set of question procedures which include a reference to another procedure and also answer procedures which include references to other procedures. Questions are dynamically generated by executing a question procedure which, in turn, calls a referenced procedure to generate a result based on one or more previous answers by the user. The referenced procedure passes the result to the question procedure for use in generating the question. The same process is used for dynamically generating answer choices for the questions. The referenced procedures may include, among other things, fetches of previous answers, conditional statements that choose among possible results based on a previous answer, or references to still other procedures. With this system, the questions and answers are kept current as the user moves through them.Type: GrantFiled: October 7, 1997Date of Patent: October 5, 1999Assignee: Expert Systems Publishing Co.Inventors: Fred D.

Patent number: 5963711Abstract: A polishing apparatus comprises a polishing member for polishing a workpiece and a manipulator for manipulating the workpiece and having a base disposed at a coordinate origin of a base coordinate system. The polishing member and workpiece define therebetween a contact surface having a contact surface coordinate system relative to an initial coordinate system defined when the polishing member and the workpiece initially contact one another at the contact surface but before a force is exerted on the contact surface to polish the workpiece. A first control device successively updates a position and attitude of the contact surface coordinator system with respect to the initial coordinate system on the basis of a deviation between preselected values of force and moment acting on the workpiece and detected values of force and moment acting at the contact surface between the polishing member and the workpiece when a force is exerted on the contact surface to polish the workpiece.Type: GrantFiled: October 8, 1996Date of Patent: October 5, 1999Assignee: Seiko Seiki Kabushiki KaishaInventor: Akira Shimada

Patent number: 5950181Abstract: In an apparatus and a method for detecting and assessing a spatially discrete dot pattern disposed in a multidimensional coordinate system, each dot in the pattern assumes at least two differentiatable status values. A measuring device records the coordinate values and status values of each dot of the multidimensional spatial dot pattern. A memory stores data that correspond to the recorded coordinate values and status values of each dot of the multidimensional spatial dot pattern. A computer into which the stored data are entered and in which a coordinate counter for each coordinate value of a coordinate axis is determined from the stored data, is associated with the memory. The value of the coordinate counter is formed from the number of detected dots of the coordinates that have a predetermined status value. A neural network is associated with the computer.Type: GrantFiled: January 6, 1997Date of Patent: September 7, 1999Assignee: Siemens AktiengesellschaftInventor: Peter Federl

Patent number: 5950182Abstract: An automatic data flow architecture builder is disclosed that is operable to take raw data which is stored in a raw data buffer (60) and transform it for storage in a transformed data buffer (78). A plurality of transform blocks (68), (70) and (72) are provided for this transform operation, these disposed in a predetermined data flow. When the user inputs a new transform to be disposed within the data flow of the transforms, rules are applied via a rule-base processing system (74) to apply a set of predetermined rules in a rule database (76) to the transform. These rules determine where the transform is to be inserted. This provides an automatic construction operation of a data flow architecture.Type: GrantFiled: January 30, 1998Date of Patent: September 7, 1999Assignee: Pavilion Technologies, Inc.Inventors: Devendra Bhalchandra Godbole, Steven Arthur O'Hara, Mary Anne Harding, Joshua Brennan Ellinger

Patent number: 5943663Abstract: An inherently, and massively parallel data processing system and methodology is disclosed for evolving relative awareness, and related response states in a computerized environment. Any number of disparate data types can be configured with the goal of evolving complex data patterns involving these data forms across relative time and space. New data processing principles and a methodology are provided based on a new default logic that emulates the logic of the force of gravity as applied to proximity in time, space and form. Data form standards are provided that require time, place, and form factors at every convergent processing step. This system is capable of evolving complex awareness states as represented by ever larger associations of the original data samples without the need for knowledge bases, conditional rules or the like. Patterns are discerned in an emergent manner.Type: GrantFiled: December 13, 1997Date of Patent: August 24, 1999Inventor: Gary C. Mouradian
