K-Means is a clustering algorithm which is used for cluster analysis in data mining; it partitions the data set into k clusters. In this project, K-Means algorithm is optimized using PSO (Parm Swarm Optimization)in terms of time. PSO simulates the social behavior of birds and helps to improve candidate solution iteratively. This project is made

Dynamic particle swarm optimization and K-means

Furthermore, the two shortcomings will be amplified in the combination of PSO and K-means and result in less efficient algorithm or poor representation of data. Therefore, in recent years, it has been a hot issues how to combine PSO with K-means clustering to obtain more effective algorithm in the fields of image segmentation.

5 Amazing Types of Clustering Methods You Should Know

Partitioning algorithms are clustering techniques that subdivide the data sets into a set of k groups, where k is the number of groups pre-specified by the analyst. There are different types of partitioning clustering methods. The most popular is the K-means clustering (MacQueen 1967), in which, each cluster is represented by the center or means of the data points belonging to the

The K-means clustering algorithm is used to find groups which have not been explicitly eled in the data. This can be used to confirm business assumptions about what types of groups exist or to identify unknown groups in complex data sets. Once the algorithm has been run and the groups are defined, any new data can be easily assigned to the correct group.
