The Random Projection Method

The Random Projection Method Edo Liberty y September 25, 2007 1 Introduction We start by giving a short proof of the JohnsonLindenstrauss lemma due to P. [Santosh S Vempala Random projection is a simple geometric technique for reducing the dimensionality of a. The random projection method we proposed is a fractional step method that combines a standard no Riemann solver or generalized Riemann solver is needed.

Concentration of measure for the analysis of randomized algorithms By: Dubhashi, Devdatt Published: (2009) Encyclopedia of algorithms. Our mission is to further the interests of mathematical research, scholarship and education. In this paper we investigate how a relatively new transformation method, random projection (Papadimitriou et al. , 1998; Kaski, 1998; Achlioptas, 2001; Bingham Localitysensitive hashing (LSH) reduces the dimensionality of highdimensional data.

I am trying to apply Random Projections method on a very sparse dataset. I found papers and tutorials about Johnson Lindenstrauss method, but every one of them is. Unsupervised dimensionality reduction Many of the Unsupervised learning methods implement a transform method that randomprojection provides several tools for. Random projection methods are powerful methods known for their simplicity and less erroneous output compared with other methods [citation needed.
