WebK-means is one of the most straightforward algorithm which is used to solve unsupervised clustering problems. In these clustering problems we are given a dataset of instances and the dataset is defined with the help of some attributes. Each instance in the dataset has some relevant values corresponding to those attributes. WebK-means algorithm tends to work well only when the clusters are spherical and have similar sizes. It may not perform well if the clusters are of different shapes, densities, or sizes. In such cases, alternative clustering algorithms such as hierarchical clustering or DBSCAN may be more appropriate. 2.
