One of the most often used methods of linear dimension reduction is principal component analysis (PCA). It can be used both on its own and as a starting point for further dimension reduction techniques.

By projecting the data onto a set of orthogonal axes, the projection-based PCA approach changes the data. An unsupervised linear transformation method known as Principal Component Analysis (PCA) is frequently utilized in a variety of domains, most notably for feature extraction and dimensionality reduction. Data compression, made possible by dimensionality reduction, results in less storage space being used. It speeds up computation. It also aids in removing any extraneous features. Since PCA is a variance-maximizing activity, normalization is crucial. our original data is projected in a manner that maximizes variance.

quester [9]

Answer:

C."How to Become a Dentist." Occupational Outlook Handbook. Bureau of Labor Statistics and US Department of Labor, 29 March 2012. Web. 1 May 2013.

Explanation:

When citing an online publication without a known author, the title of the article is first stated and encapsulated in italics. This is then followed by the name of the website or book. The organization responsible for the write-up is indicated. A comma separates the name of the organization and the date when the article was written. 'Web' is written to show that the material was obtained online. Finally, the date that tells when the article was retrieved is noted.

This guideline applies to both the Modern Language Association and the American Psychological Association citation styles.
