Abstract: In the field of electronic or computerised control apparatuses, known methods of compensating for disturbance signals rely on less than ideal analytical or empirical models. There is provided a controller (200) or method of controlling which observes and learns the correlation between various measured signals and automatically learns how to control the apparatus.

Abstract: A method for computing all occurrences of a compound event from occurrences of primitive events where the compound event is a defined combination of the primitive events. The method includes the steps of: (a) defining primitive event types; (b) defining combinations of the primitive event types as a compound event type; (c) inputting the primitive event occurrences, such occurrences being specified as the set of temporal intervals over which a given primitive event type is true; and (d) computing the compound event occurrences, such occurrences being specified as the set of temporal intervals over which the compound event type is true, where the sets of temporal intervals in steps (c) and (d) are specified as smaller sets of spanning intervals, each spanning interval representing a set of intervals.

Abstract: A current first state, of a first temporal sequence of respective first states of a dynamically modifiable system, is determined. The first current state of the system is determined by combining a first system-inherent information flow comprising past system information of the system with a second system-inherent information flow comprising future system information in the first current state. The first current state is then determined from the combination.

Abstract: A classification apparatus, notably for uses in recognition or characterisation of odors, comprises a plurality of sensors for generating raw data representing a plurality of instances of a plurality of different classes; and a processing unit for processing said raw data so as to determine an identification model. The identification model comprises definitions of the classes and a particular allocation rule selected dependent upon the application. The class definitions are established by analysing data obtained during a learning phase, the analysis being performed according to a particular information extraction method. During a later identification phase, the identification model enables an instance of unknown class to be allocated to an appropriate class amongst those defined during the learning phase. The information extraction method can be selected dependent upon the application.

Abstract: A travel purchasing optimization system consists of a cognizer in communication with a knowledge base and a rule base. A knowledge acquisition and rule manager (KARM) dynamically creates, alters, and adaptively fine tunes rules for the rule base from existing business knowledge using a rule modeling language. A travel request is made through an external booking system and sent to the cognizer via an integration framework and the knowledge base. The integration framework pools data from a series of external systems or databases and the cognizer compares the rules from the rule base with the pooled data from the integration framework. The cognizer generates the total cost of travel (TCOT) and sends the TCOT back to the external booking system via the integration framework.

Abstract: A technique is used in embodiments of the invention such that backtracking programs can be written in a general purpose computer language (e.g., C++ or Java) without requiring the control structure of the program to reflect the structure of the decision tree. A data state and a control state are restored during backtracking. For restoring the data state, embodiments of the invention keep track of the changes made to variables and the point in execution at which the changes are made. When backtracking occurs, the data state can be restored by undoing the changes to the desired point in execution. For restoring the control state, the method of the invention provides a “failure” exception state that is invoked upon failure in the program (e.g., a failure to find a solution in a search program). The failure exception is “caught” by catch points established in the execution stack.

Abstract: A device in accordance with the present invention includes drive circuitry (110) coupled to a plant (120). The drive circuitry (110) generates a first set of command signals to transition the state of the plant (120) from an initial state to an intermediate state at a first discrete time. The drive circuitry (110) generates a second set of command signals to transition the state of the plant (120) from the intermediate state to the final state at a second discrete time. A state estimator (130) is coupled to the plant to detect the state of the plant (120). A method for changing the state of a plant (120) is also provided. The method includes the steps of transitioning the plant (120) from a first state to a selected state at one of a plurality of discrete times, each of the discrete times being separated by at least one discrete time interval, and transitioning the plant (120) from the selected state to a final state at another of the plurality of discrete times.

Abstract: A computer-understandable knowledge base for accumulating computer-understandable task knowledge and a know-how knowledge base for accumulating know-how knowledge understandable for a human being are provided. In accordance with, for example, a result of the process for solving a problem which has been performed by the computer-understandable knowledge base 1, know-how knowledge relating to the problem solution is automatically retrieved and presented. Since know-how knowledge relating to the problem solution is automatically retrieved and presented in accordance with the state of the problem solving process which has been performed by the computer-understandable knowledge base, a user is able to efficiently make a reference to required know-how knowledge without a complicated process for conditions for retrieving the know-how knowledge. Even if a problem cannot be solved by the computer-understandable knowledge base, the know-how knowledge is used to guide the problem solution.

Abstract: A system for predicting a blood glucose level is comprised of a time series measurement data storing section for storing blood glucose level measured data in a blood glucose time series file to treat the data as time series data. A dynamics estimating section estimates a dynamics which most preferably represents a phase characteristic of the time series data stored in the time series measurement data storing section. A parameter storing section stores an embedding dimension n and a time delay .tau. of the dynamics estimated in the dynamics estimating section as parameters for embedding the estimated dynamics in multidimensional state space. A blood glucose predicting section predicts a near future value of blood glucose level by means of the Local Fuzzy Reconstruction Method on the basis of the stored data of the blood glucose level data stored in the blood glucose time series file and the parameters corresponding to the data and for storing the predicted future value in a predicted blood glucose level file.

Abstract: A data processing apparatus comprises apparatus arranged to model a number of modules (302,314) with each module containing a number of interconnected behaviours (320-325). A behaviour identified as a marker (304) is able to access a behaviour (321) within another module via an identify link (306) and from information denoting that behaviour within a look-up table (312) held in a further behaviour (310). Having established access, a direct identify link (316) can be set up between the selected behaviour (321) and a nominated behaviour (318) within the module containing the marker. This direct identify link is maintained when the identify link between the marker and the further behaviour is terminated, allowing the marker to go on and establish other direct links (330) to the internal behaviours of other modules (336).

Abstract: An intelligent help system which processes information specific to a user and a system state is described. The system incorporates a monitoring device to determine which events to store as data in an historical queue. These data, as well as non-historical data (e.g. system state), are stored in a knowledge base. An inference engine tests rules against the knowledge base data, thereby providing a help tag. A display engine links the help tag with an appropriate solution tag to provide help text for display.
