To activate and use connections, a complexity term defined by an equation was added to a standard quadratic error function. In experiments, a method was used in which a derivative of the complexity term was normally effective for positive connections, while negative connections were pushed toward smaller values. Thus, some connections were expected to be activated and were large enough to speed up learning. It was confirmed that the complexity term was effective in increasing the variance of the connections, especially the hidden connections. It was also confirmed that eventually some connections, especially some hidden connections, were activated and were large enough to be used in speeding up learning.<<ETX>>","PeriodicalId":390273,"journal":{"name":"CompEuro 1992 Proceedings Computer Systems and Software Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114809202","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 concept defines a virtual environment that allows the finite state machine to be an entirely table driven software module. A hybrid finite state model is used to achieve a superior design clarity. The method separates the control part of the design problem from the data manipulation part. The specification of the control part is directly executable. The control part is not coded. It is expressed in a table that is executed by the virtual finite state machine executor. The concept of virtual environment has been utilized for the design of complex software control systems.<<ETX>>","PeriodicalId":390273,"journal":{"name":"CompEuro 1992 Proceedings Computer Systems and Software Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123271187","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 distribution database model upon which the algorithm is based is the model introduced by D.A. Menasce and R.R. Muntz (1979). The main contribution is the use of automata theory for modeling the formal specification of the algorithm. This mathematical model allows the development of an elegant and short proof of correctness. The algorithm reports all true deadlocks and generates a unique candidate for resolving the deadlock.<<ETX>>","PeriodicalId":390273,"journal":{"name":"CompEuro 1992 Proceedings Computer Systems and Software Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130113282","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}

Two other multilayer neural networks, sum-of-products and a newly devised neural network called hybrid sum-of-products, had misclassification rates of 10% and 7%, respectively. The best pattern recognition technique for this application was found to be the perceptron, which provided a misclassification rate of 23%. The worst pattern recognition technique was found to be the Bayes theorem method, which provided a misclassification rate of 54%.

Multichip modules are a very effective approach to achieve high packaging density, excellent cooling and high electrical performance of mainframe processors. Two characteristic approaches are compared, namely an MCM with flip-chip mounting and an MCM with micropacks. The electrical characteristics of chip-to-board connections, microwiring substrates and planar module connectors have to be carefully designed. The ICs should preferably be BiCMOS AS ICs with up to 80000 gate functions with optional embedded SRAMs of up to 360000-bit capacity. The mechanical construction, wiring and delay rules, and test requirements for such chips are considered.<<ETX>>","PeriodicalId":390273,"journal":{"name":"CompEuro 1992 Proceedings Computer Systems and Software Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126532302","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}
