In order to discover more practical rules, domain knowledge such as taxonomies of items [9] and similarity among items [11] have been considered to produce generalized association rules and similar association rules respectively. However, these algorithms deal with only transactions with binary values whereas transactions with quantitative values are more commonly seen in real-world applications. This paper thus proposes a new data-mining algorithm for extracting fuzzy knowledge from transactions stored as quantitative values. The proposed algorithm integrates fuzzy set concepts and the a priori mining algorithm to find fuzzy similar association rules in given transaction data sets where similarity relations are assumed among database items. The rules discovered here thus promote coarser granularity of association rules and exhibit quantitative regularity under similarity relations.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.

For this purpose the clustering and orthogonal transformation methods are the essential tools. The determination of clusters representing fuzzy rules with the consideration of output as well as input spaces is essential. To select orthogonal axes as principal components other than those determined by Gram-Schmidt provides a most compact representation of the input space R/sup p/ with the p premise variables. This approach in principle possesses two important features for fuzzy modeling. On one hand an enhanced effective rule selection, with the consideration of consequence, is obtained. On the other hand substantial computational saving relative to conventional orthogonal-least-squares approach or other conventional clustering methods is achieved.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.

This paper discusses two of these approaches, the fuzzy semantic typing of Subasic and Huettner and the computational semiotics of Rigger. From a theoretical point of view, such methods have been criticized on both philosophical and linguistic grounds. lit this paper, we perform some simple experiments to see whether useful insights or even useful text processing methods can be gleaned from application of techniques derived from one of these pragmatic approaches (computational semiotics). We conclude that the results are inconsistent and provide neither useful surface measures of regularities nor insights into underlying syntactico-semantic properties of linguistic utterance.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.

We describe a variety of modifications that we have made to the data mining algorithms in order to improve accuracy and efficiency. We use sets of fuzzy association rules that are mined from network audit data as models of \"normal behavior.\" To detect anomalous behavior, we generate fuzzy association rules from new audit data and compute the similarity with sets mined from \"normal\" data. If the similarity values are below a threshold value, an alarm is issued. We describe an algorithm for computing fuzzy association rules based on Borgelt's (2001) prefix trees, modifications to the computation of support and confidence of fuzzy rules, a new method for computing the similarity of two fuzzy rule sets, and feature selection and optimization with genetic algorithms. Experimental results demonstrate that we can achieve better running time and accuracy with these modifications.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.

This problem occurs in production planning management whereby a decision maker plays an important role in making decision in a fuzzy environment. As an analyst, we try to find a solution which is good enough for the decision maker to make a final decision. We have considered this problem because all the parameters such as objective coefficient, technical coefficient and resource variables are uncertain. This is considered as one of sufficiently large problem involving 29 constraints and 8 variables. A decision maker can identify a performance measure for making a decision that is suitable for achieving satisfactory profit. The decision maker can also suggest to the analyst some possible and practicable changes in fuzzy intervals for improving the satisfactory profit. This interactive process has to go on an on among the analyst, the decision maker and the implementer till an optimum satisfactory decision is achieved and implemented.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.

The relation among object predicates is defined by object trees that are fully capable of dynamic growth and maintenance. The qualitatively fuzzy inference engine and the developed expert system can then acquire a virtual-rule space that is exponentially (subject to machine implementation constants) larger than the actual, declared-rule space and with a decreasing non-zero likelihood of error. This capability is called knowledge amplification, and the methodology is named KASER. KASER is an acronym for Knowledge Amplification by Structured Expert Randomization. It can handle the knowledge-acquisition bottleneck in expert systems. KASER represents an intelligent, creative system that fails softly, learns over a network, and has enormous potential for automated decision making. KASERs compute with words and phrases and possess capabilities for metaphorical explanations.","PeriodicalId":348314,"journal":{"name":"2002 Annual Meeting of the North American Fuzzy Information Processing Society Proceedings.
