Abstract: Data mining is the combination of data assembled by customary information mining philosophies and procedures with data accumulated over a period of time. Mining means extricating something helpful or important from an already existing data. This paper is intended to review time series analysis and clustering techniques. The clustering algorithms which are investigated are K-Means and Hierarchical Clustering. Also a review is also conducted on Time Series based clustering.

Keywords: Data Mining, K-Means Algorithm, Hierarchical clustering algorithm, Time Series analysis.
