The authors discuss the requirements of learning for generalization, which is NP-complete and cannot be approached by traditional methods based on gradient descent. They present a stochastic learning algorithm based on simulated annealing in weight space. The convergence properties and feasibility of the algorithm are verified.<<ETX>>","PeriodicalId":339677,"journal":{"name":"[1989] Proceedings of the Thirteenth Annual International Computer Software & Applications Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126358357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the overall operational consistency of a database rests on this crucial assumption, there are few design aids to support the design of consistent transaction programs. An approach is presented for verifying that the defined integrity constraints are not violated by a transaction program. Assuming that the database is in a consistent state before the transaction program starts, the database stays consistent after the execution of a correct transaction program. In this approach all computations and all modifications on the database are identified and represented with symbolic values. The symbolic representation of the output variables and database operations is used to verify the integrity constraints. Therefore, it is possible to support the application programmer in designing correct transaction programs.<<ETX>>","PeriodicalId":339677,"journal":{"name":"[1989] Proceedings of the Thirteenth Annual International Computer Software & Applications Conference","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127188151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is called lexically scoped concurrent LISP (LS/CL). LS/CL is based on Common LISP. Local variables are lexically scoped and the functions, except for concurrent functions, are defined to satisfy the language specifications of Common LISP. Processes of LS/CL are dynamically created and cooperate with each other. In addition to the language features, this paper shows the environment management mechanism of dynamically activated processes that have statically scoped variables. Also described is the LS/CL system implemented on a workstation.<<ETX>>","PeriodicalId":339677,"journal":{"name":"[1989] Proceedings of the Thirteenth Annual International Computer Software & Applications Conference","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132806031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expert system employs management information provided by a monitoring mechanism of the network. The whole spectrum of the fault management information is analyzed. The management knowledge derived is categorized into five types: the physical property, the experience in the past, the heuristic rule of thumb, the predictable problems, and the deep knowledge. These knowledge types and related rules are divided into groups to improve reasoning speed. The expert system is composed of a problem manager, a problem analyzer, and many problem solvers. A prototyped expert system, using simulated faults, shows that the expert-system-based fault management system can automatically diagnose problems and take corrective actions.<<ETX>>","PeriodicalId":339677,"journal":{"name":"[1989] Proceedings of the Thirteenth Annual International Computer Software & Applications Conference","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116010981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It integrates the concepts and techniques of semantic modeling and those introduced by the object-oriented paradigm. Unlike conventional data models such as the relational model, the object orientation of OSAM allows the user to model an application in terms of complex objects, classes and their associations, instead of tuples (or records) and relations (or record types). The primitives (objects, class, instance and link) and the perspectives (class and object) of an OSAM database are described. Key differences between OSAM and a conventional object-oriented model are discussed. The features of object orientation and explicit definition of semantic associations among objects allow the database of an application domain to be modeled, accessed and manipulated at a higher conceptual level and thus simplify the tasks of the users in the development of their applications.<<ETX>>","PeriodicalId":339677,"journal":{"name":"[1989] Proceedings of the Thirteenth Annual International Computer Software & Applications Conference","volume":"409 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114940782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
