KMeans is a clustering algorithm which is used for cluster analysis in data mining it partitions the data set into k clusters. In this project, KMeans algorithm is optimized using PSO Parm Swarm Optimizationin terms of time. PSO simulates the social behavior of birds and helps to improve candidate solution iteratively. This project is made in python and has been tested on some standard

Moreover, kMeans best ts data sets with spherical clusters of almostequal volumes. The rst drawback is partially alleviated if smarter initialization schemes are used. The initial centroids should be placed far apart, or a hierarchical clustering method may be used to return an initial partition over a small sample of the data set.
Combining PSO and kmeans to Enhance Data Clustering PSO and K means algorithms to group a given set of data into a userspecified number of clusters. Elkamel et al. 15 proposed the
The new PSO algorithms are evaluated on six data sets, and compared to the performance of Kmeans clustering. Results show that both PSO clustering techniques have much potential. View
Tutorial on how to apply KMeans using Weka on a data set.
set and it is extractable through data mining techniques. Present paper is designed to justify the capabilities of data mining techniques in context of higher education by offering a data mining model for higher education system in the university. In this research, the classification task is used to evaluate students
Data Mining for Education Ryan S.J.d. Baker, Carnegie Mellon University, Pittsburgh, Pennsylvania, USA the National Center for Education Statistics NCES data sets has created a base which makes Clustering algorithms can either start with no prior hypotheses about clusters in the data such as the kmeans algorithm with randomized
2 kmeans Clustering In this section, we briey describe the direct kmeans algorithm 9, 8, 3. The number of clusters is assumed to be xed in kmeans clustering. Let the prototypes be initialized to one of the input patterns .1 Therefore, 34amp39 , 39 . Figure 1 shows a high level description of the direct kmeans clustering
Combining PSO and kmeans to enhance data clustering Abstract In this paper we propose a clustering method based on combination of the particle swarm optimization PSO and the kmean algorithm. PSO algorithm was showed to successfully converge during the initial stages of a global search, but around global optimum, the search process will
3. PSOKmeans 3.1 Procedure of PSOKmeans 1. In the context of PSOKmeans clustering, before initializing the particles, the data points are randomly assigned to K clusters first. 2. Particle fitness is evaluated based on clustering criteria. i K 2 Fj 1 N x Cx K j i 1 3
Clustering Multidimensional Data with PSO based Algorithm Jayshree GhorpadeAher and Vishakha A. Metre Abstract Data clustering is a recognized data analysis method in data mining whereas KMeans is the well known partitional clustering method, possessing pleasant features.
This second algorithm basically uses PSO to refine the clusters formed by Kmeans. The new PSO algorithms are evaluated on six data sets, and compared to the performance of Kmeans clustering.
3.1. Kmeans algorithm Kmeans algorithm is first applied to an Ndimensional population for clustering them into k sets on the basis of a sample by MacQueen in 1967 9. The algorithm is based on the input parameter k. First of all, k centroid point is selected randomly. These k centroids are the means of k clusters. Then, each item in the
Data mining in higher education Data mining is a powerful tool for academic intervention. Through data mining, a universitycould, for example, predict with 85 percent accuracy which students will or will not graduate. The university could use this information to concentrate academic assistance on those students most at risk.
1. Introduction. Clustering analysis is a very popular data mining technique. It is the process of grouping a set of objects into clusters so that objects within the same cluster are similar to each other but are dissimilar to objects in other clusters Han et al., 2001, Jain et al., 1999, Maimon and Rokach, 2005.When a set of objects has been applied to by a clustering algorithm, the
Educational Data Mining EDM is a field that uses machine learning , data mining, and statistics to process educational data, aiming to reveal useful information for analysis and decision making.

The demand and scope for privacy is increasing daybyday as data storage techniques have emerged from standalone database to distributed database and then progressed to parallel databases. Kmeans and Fuzzy Cmeans FCM are the frequently used clustering algorithms for standalone database, distributed database and parallel databases.
Particle Swarm Optimization, ACO Ant Colony Optimization and Kmeans algorithm, which can find the cluster partition. After choosing the cluster centers, Kmeans clustering is applied for the clustering process. As the same way kmedoids also begins with randomly selecting k data items as initial medoids to represent the K
