PCA is a useful statistical technique that has found application in ﬁelds such as face recognition and image compression, and is a common technique for ﬁnding patterns in data of high dimension.

Principal component analysis (PCA) is used to summarize the information in a data set described by multiple variables. Note that, the information in a data is the total variation it contains. PCA reduces the dimensionality of data containing a large set of variables.

Principal component analysis (PCA) is among the most pop-ular tools in machine learning, statistics, and data analysis more generally. PCA is the basis of many techniques in data mining and information retrieval, including the latent semantic analysis of large databases of text and HTML documents described in [1]. In this paper, we compute PCAs of very large data sets via a randomized version

number of observations present new challenges in data, mining, analysis and classification. Traditional statistical method breaks down partly because of the increase in the number of variables associated with each observation which is known as high dimensional data. Much of the data is highly redundant which can be ignored to extract features of dataset. The process of mapping of high
