However, \"is feature-value/spl ges/thrsh\" type of tests used in tree classifiers are often found sensitive to noise and minor variations in the data. This has led to the use of soft thresholding in decision trees. Following the decision tree to feedforward neural network mapping of the entropy net, three neural implementation schemes for tree classifiers, that allow soft thresholding, are presented in this paper. Results of several experiments using well-known data sets are described to compare the performance of the proposed implementations with respect to decision trees with hard thresholding. >","PeriodicalId":79994,"journal":{"name":"IEEE transactions on systems, man, and cybernetics","volume":"131 1","pages":"1243-1249"},"PeriodicalIF":0.0,"publicationDate":"1995-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82255132","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 based on previous work on efficient O(N) algorithms, where N is the number of links in the manipulator, and has been extended to include the effects of a mobile base (the URV body). In addition, the various hydrodynamic forces exerted on these systems in underwater environments are also incorporated into the simulation. The effects modeled in this work are added mass, viscous drag, fluid acceleration, and buoyancy forces. With efficient implementation of the resulting algorithm, the amount of computation with inclusion of the hydrodynamics is almost double that of the original algorithm for a six degree-of-freedom land-based manipulator with a mobile base. Nevertheless, the amount of computation still only grows linearly with the number of degrees of freedom in the manipulator. >","PeriodicalId":79994,"journal":{"name":"IEEE transactions on systems, man, and cybernetics","volume":"45 1","pages":"1194-1206"},"PeriodicalIF":0.0,"publicationDate":"1995-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78572662","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 optimal control consists of minimizing the travel time of guided vehicles using a queue-based model. The optimization is based on the use of forward dynamic programming and decomposition-coordination methods. Driver's compliance is modeled by a linear function of the guidance advice (control). An assessment of the criteria degradation induced by nonperfect compliance is performed. Results show that this degradation of the criteria is low in fluid traffic conditions but high in congested situations. Thus human factors cannot be neglected in route guidance systems. >","PeriodicalId":79994,"journal":{"name":"IEEE transactions on systems, man, and cybernetics","volume":"25 1","pages":"1161-1165"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81780314","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}

We propose a prescriptive theory of human-computer cooperative problem solving and describes the design and evaluation of a prototype system based on the theory. The theory consists of five principles: human-in-charge, mutual intelligibility, openness and honesty, management of trouble, and multiple perspectives. A prototype intelligent associate system, the Georgia Tech Mission Operations Cooperative Assistant (GT-MOCA), is an embodiment of these principles that provides a collection of context-sensitive resources for the human operator of a simulated satellite ground control system. These resources include an interactive visualization of current activities, an organized message lists of important events, and interactive graphics depicting the current state of the controlled system. An evaluation study utilizing actual NASA satellite ground controllers showed that GT-MOCA was perceived to be useful and provided performance benefits for certain portions of the control task. >","PeriodicalId":79994,"journal":{"name":"IEEE transactions on systems, man, and cybernetics","volume":"91 1","pages":"1039-1053"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82143262","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}

Ram","doi":"10.1109/21.391290","DOIUrl":"https://doi.org/10.1109/21.391290","url":null,"abstract":"Job shop scheduling belongs to the class of NP-hard problems. There are a number of algorithms in literature for finding near optimal solution for the job shop scheduling problem. Many of these algorithms exploit the problem specific information and hence are less general. However, the simulated annealing algorithm for job shop scheduling is general and produces better results in comparison with other similar algorithms. But one of the major drawbacks of the algorithm is that the execution time is high. This makes the algorithm inapplicable to large scale problems. One possible approach to reduce the execution time of the algorithm is to develop distributed algorithms for simulated annealing. In the paper, the authors discuss approaches to developing distributed algorithms for simulated annealing for solving the job shop scheduling problem. Three different algorithms have been developed. These are the temperature modifier, the locking edges and the modified locking edges algorithms. These algorithms have been implemented on the distributed task sharing system (DTSS) running on a network of 18 Sun workstations. The observed performance showed that each of these algorithms performs well depending on the problem size. >","PeriodicalId":79994,"journal":{"name":"IEEE transactions on systems, man, and cybernetics","volume":"20 1","pages":"1102-1109"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73078326","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}
