A Rough Set Approach in Choosing Partitioning Attributes
Data mining partitioning is performed on attributes to increase data concentration. To choose effective partitioning attributes, a rough set based technique that measures the crispiness of the partitioning is presented. This technique is based on the mathematical theory of rough sets. This method is a simple and efficient approach to measure the crispiness of the partition in data mining.
متن کاملRough-Set Multiple-Criteria ABC Analysis
Multiple-criteria ABC (MCABC) analysis is conducted using a dominance-based rough set approach. ABC analysis, a well-known technique for inventory planning and control, divides stock-keeping units (SKUs) into three classes according to annual dollar usage. But MCABC analysis offers more managerial flexibility by including other criteria, such as lead time and criticality, in the classification ...
متن کاملRough-Set based Criteria for Incremental Rule Induction
This paper proposes a new framework for incremental learning based on accuracy and coverage. Classified addition of example into four cases, two inequalities for accuracy and coverage are obtained. The proposed method classifies a set of formulae into three layers: rule layer, subrule layer and non-rule layer by using the inequalities obtained. Then, subrule layer plays a central role in updati...
متن کاملA Rough Set Approach to Multiple Criteria ABC Analysis
A dominance-based rough set approach (DRSA) to multiple criteria ABC analysis (MCABC) is designed and compared to other approaches using a practical case study. ABC analysis is a well-known inventory planning and control approach, which classifies inventory items, or stock-keeping units (SKUs), based solely on their annual dollar usage. Recently, it has been suggested that MCABC can provide mor...
