Rough Sets, Bayes’ Theorem and Flow Graphs
Rough set theory is a new approach to vagueness and uncertainty. The theory of rough sets has an overlap with many other theories. Specially interesting is the relationship to fuzzy set theory and the theory of evidence. Recently, it turned out that the theory has very interesting connections with Bayes’ theorem. The look on Bayes’ theorem offered by rough set theory reveals that any data set (...
متن کاملDecision Rules, Bayes' Rule and Ruogh Sets
This paper concerns a relationship between Bayes’ inference rule and decision rules from the rough set perspective. In statistical inference based on the Bayes’ rule it is assumed that some prior knowledge (prior probability) about some parameters without knowledge about the data is given first. Next the posterior probability is computed by employing the available data. The posterior probabilit...
متن کاملRough Sets and Association Rule Generation
ASSOCIATION RULE see extraction methods have been developed as the main methods for mining of real life data in particular in Basket Data Analysis In this paper we present a novel ap proach to generation of association rule based on Rough Set and Boolean reasoning methods We show the relationship between the problems of association rule extraction for transaction data and relative reducts or re...
متن کاملCombining rough sets and rule based classifiers for handling imbalanced data
The paper presents two rough sets based filtering approaches combined with rule based classifiers suited for handling imbalanced data sets, i.e., data sets where the minority class of primary importance is under-represented in comparison to the majority classes. We introduced two techniques to detect and process inconsistent majority cases in the boundary between the minority and majority class...
متن کاملGranularity, Multi-valued Logic, Bayes’ Theorem and Rough Sets
Granularity of knowledge attracted attention of many researchers recently. This paper concerns this issue from the rough set perspective. Granularity is inherently connected with foundation of rough set theory. The concept of the rough set hinges on classification of objects of interest into similarity classes, which form elementary building blocks (atoms, granules) of knowledge. These granules...
