In this paper, an attempt has been made to explore the effect of frequency of co-occurrence of features on the accuracy of the clustering results. This has been achieved by incorporating the frequency component in the clustering algorithm. The frequency, we mean here is the number of times the sequence of features appear in the data set. We try to utilize this component in the algorithm and study...
An important goal in data mining is to generate an abstraction of the data. Such an abstraction helps in reducing the time and space requirements of the overall decision making process. It is also important that the abstraction be generated from the data in small number of scans. In this paper, we propose a novel data structure called prefix-postfix structure(PP-structure), which is an abstraction...
