We compare in this paper several feature selection methods for the Naive Bayes Classifier (NBC) when the data under study are described by a large number of redundant binary indicators. Wrapper approaches guided by the NBC estimation of the classification error probability outperform filter approaches while retaining a reasonable computational cost.

In fund raising management the employment of a decision support system is crucial for optimising the results of fund raising campaigns. However, the current tools based on database technology are not able to suggest suitable fund raising strategies and the support to the fund raiser is limited to give general indications in relation to specific claims. In this paper, we present a fuzzy knowledg...

Cooperative games are real-valued lattice functions quantifying the TU (transferable utility) worth of cooperation within a (finite) player set. A fundamental issue is how to share this worth amongst the players, i.e., the solution problem. Although cooperative games were originally conceived exclusively in terms of coalitional games, associating a worth to each coalition, later more complex ga...

Source code and Test data – 1 CD ii Abstract Email is using by hundred of millions of people worldwide. Unfortunately, the widespread use of email has given rise to several problems. Redundant email is one of them. In this project we are exploring a solution to that problem by examining the applicability of duplicate detection method in eliminating redundant emails. Following fingerprint techni...

The rules of Sudoku are often specified using twenty seven all different constraints, referred to as the big constraints. Using graphical proofs and exploratory logic programming, the following main and new result is obtained: many subsets of six of these big constraints are redundant (i.e., they are entailed by the remaining twenty one constraints), and six is maximal (i.e., removing more than...

We present a general method for detecting redundant production rules based upon a term rewrite semantics. We present the semantic account, define rule execution over both ground memories and memory schemas, and define redundancy for production rules. From those definitions, an algorithm is developed that detects redundant rules, and which improves upon previously

Multiple calls to the same function using the same argument values are often redundant, and the result of the earlier call can be reused. This is similar to the reuse of redundant arithmetic expressions in redundancy elimination. However, only calls that will return the same results and not produce side effects can be reused. In this paper we present a static analysis that determines whether ca...

This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...
