In the field of Artificial Intelligence, inference engine is a component of the system that applies logical rules to the knowledge base to deduce new information. The first inference engines were components of expert systems. The typical expert system consisted of a knowledge base and an inference engine. The knowledge base stored facts about the world. The inference engine applies logical rules to the knowledge base and deduced new knowledge. This process would iterate as each new fact in the knowledge base could trigger additional rules in the inference engine. Inference engines work primarily in one of two modes either special rule or facts: forward chaining and backward chaining. Forward chaining starts with the known facts and asserts new facts. Backward chaining starts with goals, and works backward to determine what facts must be asserted so that the goals can be achieved.

Bypassing an intermediate synchronization server of a three tiered synchronization system
InactiveUS7634519B2Data processing applicationsDatabase distribution/replicationData storeSynchronization system
A bypasser configured to operate within a three tiered synchronization system. The bypasser can include an interceptor and an inference engine. The interceptor can intercept synchronization requests before a synchronization event involving a synchronization server is initiated. The inference engine can determine if the data store and the another data store are to be synchronized and can selectively initiate the synchronization event based on the determination of the inference engine. For example, when the inference engine determines that synchronization is not to occur, the bypasser can convey a notification that no update is needed to the source of an intercepted synchronization request without requiring the synchronization server to process the synchronization request. When the inference engine determines that synchronization is to occur, the bypasser can convey an intercepted synchronization request to the intermediate synchronization server for processing.

IP network vulnerability and policy compliance assessment by IP device analysis
InactiveUS20080172716A1Reduce vulnerabilityImprove network securityTransmissionSpecial data processing applicationsNetwork security policyCompliance problem
Customizable software provides assurances about the ability of an IP network to satisfy security, regulatory and availability requirements by comprehensive vulnerability and compliance assessment of IP networks through automated analysis of configurations of devices such as routers, switches, and firewalls. The solution comprises three main approaches for testing of IP device configurations to eliminate errors that result in vulnerabilities or requirements compliance issues. The first two fall in to the “static constraint validation” category since they do not change significantly for each IP network, while the last approach involves incorporation of each specific IP network's policies / requirements. These approaches are complementary, and may be used together to satisfy all the properties described above. The first approach involves checking the configurations of devices for conformance to Best-Current-Practices provided by vendors (e.g. Cisco Network Security Policy) and organizations such as the NIST, NSA or CERT. Also this includes checks of compliance with regulations such as FISMA, SOX, HIPPA, PCI, etc. The second approach is where as one reads device configurations, one collects beliefs about network administrator intent. As each belief is collected, an inference engine checks whether the new belief is inconsistent with previously accumulated beliefs. The third approach addresses the multiple device / protocol issue by including an understanding of high-level service and security requirements about the specific IP network under test from the network administrators.

An un-indexed, partitioned temporary table and an exchange table are used in the inferencing of semantic data in a relational database system. The exchange table has the same structure as a semantic data table storing the semantic data. In the inferencing process, a new partition is created in the semantic data table. Inference rules are executed on the semantic data table, and any newly inferred semantic data generated is added to the temporary table. Once no new data is generated, the inferred semantic data is copied from the temporary table into the exchange table. Indexes that are the same as indexes for the semantic data table are built for the exchange table. The indexed data in the exchange table is then exchanged into the new partition in the semantic data table. By use of the un-indexed, partitioned temporary table, incremental maintenance of indexes is avoided, thus allowing for greater efficiency.

A machine learning based automated online form-filling technique provides for automatically completing user input controls based on previously stored information. An associative parser is used to identify and associate characteristics related to form controls with the corresponding form controls. The characteristics of the user input controls are input into a machine learning based semantic inference engine that was trained for the purpose of identifying the type of information that is supposed to be input into various user input controls. The semantic inference engine operates to label the controls in a manner that describes the meaning of the control, i.e., the type of information that should be automatically input into the corresponding controls. Consequently, the user input controls can be automatically filled in with previously stored user profile information associated with the corresponding labels.

Artificial neural network and fuzzy logic based boiler tube leak detection systems
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.
