One major obstacle for using neural network training techniques is the high necessary diagnostic quality: since only one financial transaction in a thousand is invalid no prediction success less than 99.9% is acceptable. Because of these credit card transaction requirements, completely new concepts had to be developed and tested on real credit card data. This paper shows how advanced data mining techniques and a neural network algorithm can be combined successfully to obtain a high fraud coverage combined with a low false alarm rate.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131144352","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}

Our approach is based on two considerations. On the one hand, query formulation can be considered as a skill which can be shared entirely or partly between users. Accordingly we propose a model for storing and making available this skill to help users formulate their new queries. On the other hand we base our design on custom construction of a database adapted to each business group of users in question. In using it, the users of a given business cooperate transparently through their queries to design databases specific to their business. Thus, they take part co-operatively if indirectly in reducing the difficulty of query formulation.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131665292","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}

Hamidzadeh, Ngan Kee","doi":"10.1109/TAI.1999.809806","DOIUrl":"https://doi.org/10.1109/TAI.1999.809806","url":null,"abstract":"Puzzles have traditionally been used as popular benchmarks for evaluating different problem solving strategies. Many of the game benchmarks are suitable for evaluating static scheduling techniques. In such benchmarks, the scheduling phase and the execution phase (i.e. when the schedule is executed to play the game) are disjoint. The scheduling technique can be executed to compute a complete schedule prior to the execution of any moves to play the game. Due to recent interest in on-line problem solving techniques, there is a need for benchmarks which can evaluate the performance trade-offs of dynamic scheduling techniques. Many modern video and computer games can be suitable candidates for dynamic scheduling benchmarks, since they require on-line problem solving. These benchmarks and their system testbeds should be chosen and implemented such that they can accurately reveal important performance trade-offs of dynamic scheduling techniques. In this paper, we introduce a dynamic scheduling benchmark and its system testbed. This benchmark is based on an extended version of the Tetris computer game. The rules and semantics of the game were modified to lend themselves well to evaluation of discrete problem solving and optimization techniques. The system testbed is implemented in a distributed and asynchronous fashion, on a network of workstations, to reveal performance trade-offs between scheduling time, schedule quality, and problem constraints.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131945678","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}

As the number of clients increases, the centralized database server can become a performance bottleneck. In order to overcome this scalability problem, a three-tier client-server configuration has been proposed that features the partitioning of clients into logical clusters. Here, the objective is to maximize the data sharing among the clients in each cluster. We propose a genetic algorithm to create such client clusters and evaluate two different techniques for generating the initial solution populations. We compare the performance of the two-tier and three-tier configurations with respect to the transaction turnaround times and object response times. Our experimental results indicate that the clustered architecture can offer improved performance over its two-tier counterpart.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"162 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114000936","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}

Even though this face detection method has relatively high false positives and a low detection rate (as compared with the dedicated face detection systems in the literature of image understanding), because of its simple and fast nature, it has been shown that this system may be well applied in image retrieval in certain focused application domains. Two application examples are given: one combining face detection with indexed collateral text for image retrieval regarding human beings, and the other combining face detection with conventional similarity matching techniques for image retrieval with similar background. Experimental results show that our proposed approaches have significantly improved image retrieval precision over existing search engines in these focused application domains.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124198057","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}

In this scope, instance-based learning (IBL) techniques are often used as the basic component. However, one of the major drawbacks of IBL is the prototype selection problem which consists in selecting a subset of representative instances in order to reduce the classification process. This paper presents a novel approach which consists of three steps. The first one builds a set of lattice-based hypotheses that characterize the training data set. Given an unseen example, the second step selects a subset of training instances through the way they verify the same hypotheses as the unseen example. Finally the last step uses this subset of training instances as the prototypes for the classification of the unseen example. Results of experiments that we conducted show the effectiveness of our approach compared to standard ML techniques on different datasets.","PeriodicalId":194023,"journal":{"name":"Proceedings 11th International Conference on Tools with Artificial Intelligence","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124480412","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}
