The present invention discloses an implementation of the selective attention mechanism occurring in the human brain using a conventional neural network, multi-layer perceptron and the error back-propagation method as a conventional learning method, and an application of the selective attention mechanism to perception of patterns such as voices or characters. In contrast to the conventional multi-layer perceptron and error back-propagation method in which the weighted value of the network is changed based on a given input signal, the selective attention algorithm of the present invention involves learning a present input pattern to minimize the error of the output layer with the weighted value set to a fixed value, so that the network can receive only a desired input signal to simulate the selective attention mechanism in the aspect of the biology. The present invention also used the selective attention algorithm to define the degree of attention to a plurality of candidate classes as a new criterion for perception, thus providing high perception performance relative to the conventional recognition system for a single candidate class.

Electronic data is classified using adaptive focused replicator networks (AFRNs). AFRNs are sets of array elements, each array element being trainable in order to replicate a predetermined sub-group of data. Unknown data is inputted into each and every array element in an AFRN array and then replicated by each element array. A comparison is made for each array element to determine the accuracy of each replication. If only one array element successfully replicates the unknown data, then the unknown data is classified in accordance with the corresponding predetermined sub-group of data.

A method is disclosed for determining the correctness of proposed values or data for engineering parameters. The method incorporates the use of a server side computer and a client side computer connected to each other via an electronic network. The method includes the steps of obtaining a knowledge base of data. The knowledge base is stored on the server side computer. Proposed values or data are generated at the client side computer using an applet. The proposed data is then transmitted over the network from the client side computer to the server side network. The proposed data is then compared against the knowledge base of data using a servlet designed to invoke and utilize computers other than the server side computer that may have rules or facts necessary to test the proposed data. The results are prepared and then transmitted from the server side computer to the client side computer. The client side computer does not require a proprietary application to be resident therein. It merely requires a web browser to access and utilize all of the information resident in the knowledge base stored in the server side computer.

A new model of motivational behavior, described as a ten-level metaperspectival hierarchy of ethical terms, serves as the foundation for an ethical simulation of artificial intelligence. This AI system is organized as a tandem, nested expert system, composed of a primary affective language analyzer, overseen by a master control unit-expert system (coordinating the motivational interchanges over real time). The systematic organization of the ethical hierarchy allows for extreme efficiency in the programming of the respective knowledge bases, employing the principles of inheritance for modeling the more abstract levels of the hierarchy: allowing a precise determination of the motivational level at issue during a given verbal interchange (defined as the passive-monitoring mode). An optional active monitoring mode permits the posing of simple yes-or-no questions, allowing for clarification of ambiguous language input. This basic motivational determination, in turn, serves as the basis for the synthesis of a response repertoire tailored to the computer, simulating a sense of motivation in a given verbal interaction (defined as the true AI simulation mode). The AI mode operates in concert with the passive monitoring mode, and in potential alternation with the active monitoring mode.

A system and a method for diagnosis of engine conditions are proposed. In particular, the system and the method are directed to an extraction of features from different information sources and to their processing. These features, together with a series connection of two neural networks, form the crux of the system and method, so that a dependable diagnosis of engine conditions, particularly an error recognition is possible. As a result thereof, maintenance corresponding to the current engine condition is enabled.

Power industry boiler tube failures are a major cause of utility forced outages in the United States, with approximately 41,000 tube failures occurring every year at a cost of $5 billion a year. Accordingly, early tube leak detection and isolation is highly desirable. Early detection allows scheduling of a repair rather than suffering a forced outage, and significantly increases the chance of preventing damage to adjacent tubes. The instant detection scheme starts with identification of boiler tube leak process variables which are divided into universal sensitive variables, local leak sensitive variables, group leak sensitive variables, and subgroup leak sensitive variables, and which may be automatically be obtained using a data driven approach and a leak sensitivity function. One embodiment uses artificial neural networks (ANN) to learn the map between appropriate leak sensitive variables and the leak behavior. The second design philosophy integrates ANNs with approximate reasoning using fuzzy logic and fuzzy sets. In the second design, ANNs are used for learning, while approximate reasoning and inference engines are used for decision making. Advantages include use of already monitored process variables, no additional hardware and/or maintenance requirements, systematic processing does not require an expert system and/or a skilled operator, and the systems are portable and can be easily tailored for use on a variety of different boilers.

A method and device for automatically informing an end user of a message resulting from regular analysis of data on a database. A storage 3 stores result transmission requirements 4 which is prepared for determining whether the message resulting from regular analysis of the data by a database system 1 should be transmitted to an end user 2 or not. A result fetch section 5 fetches analysis results from the database system 1. A mail host 6 transmits an e-mail addressed to the end user 2 when a fetched analysis result satisfies the result transmission requirements 4 in order to inform the end user 2 of the requirement satisfaction. The transmitted e-mail is stored in a mail server 7 via a network 8. The end user 2 obtains the e-mails addressed to him/her from the mail server 7 by operating a mail client 9. The end user 2 notices that the analysis result which satisfies the result transmission requirements 4 has been issued by the database system 1. The notice is helpful for solving problems regarding to business affairs to which the end user 2 relates.
