toolbox_dimreduc - a toolbox for dimension reduction methods
This toolbox is an educational and recreative toolbox around recent ideas in the field of dimension reduction.
This toolbox contains a set of helpers and test scripts to play with the following algorithms :
* PCA : classical Principal Componnent Analysis (linear projection).
* Isomap
A Global Geometric Framework for Nonlinear Dimensionality Reduction
J. B. Tenenbaum, V. de Silva and J. C. Langford
Science 290, 2319
* LLE
Nonlinear dimensionality reduction by locally linear embedding.
Sam Roweis & Lawrence Saul.
Science, v.290 no.5500 , Dec.22, 2000. pp.2323--2326.
* HLLE
Hessian eigenmaps: Locally linear embedding techniques for high-dimensional data
David L. Donoho and Carrie Grimes
Proc Natl Acad Sci U S A. 2003 May 13; 100(10): 5591–5596.
* Laplacian Eigenmaps
Laplacian Eigenmaps for dimensionality reduction and data representation
Mikhail Belkin and Partha Niyogi,
Neural Computation 15(16), 2003, 1373-1396
* Local Tangent Space Alignment
Principal manifolds and nonlinear dimension reduction via local tangent space alignment.
Zhenyue Zhang and Hongyuan Zha.
SIAM Journal of Scientific Computing, 26(1):313–338, 2004.
* Local PCA
Dimension Reduction by Local Principal Component Analysis
Nandakishore Kambhatla and Todd K. Leen
Neural Computation, Volume 9 , Issue 7,1997
This toolbox contains the sources provided by the authors of these articles, slightly modified to get a cleaner interface. These codes are under the copyright of the corresponding authors.
This toolbox contains tests files to see the application of these algorithm in three settings :
* Simple 3D clouds.
* 3D mesh with given connectivity.
* Images data sets.
The images data sets are borrowed from :
* Roweis datas
* MNIST handwritten digits database
They are *NOT* included in the distribution of the toolbox available on Matlab central.
The file data.zip should be retrieved from here
and unzipped in the same directory as the toolbox.
Installation: you have to put the directory toolbox/ into you matlab path.
