Laurens van der Maaten just released a large matlab toolbox featuring 25 dimensionality reduction techniques [Updated: Dec 1, 2008]. And then you can use PRTools to do your own classification. Be careful what you wish for :-)
The list of techniques readily implemented:
Principal Component Analysis (PCA)
Simple PCA
Probabilistic PCA
Linear Discriminant Analysis (LDA)
Multidimensional scaling (MDS)
Isomap
Landmark Isomap
Local Linear Embedding (LLE)
Laplacian Eigenmaps
Hessian LLE
Local Tangent Space Alignment (LTSA)
Conformal Eigenmaps (extension of LLE)
Maximum Variance Unfolding (extension of LLE)
Fast Maximum Variance Unfolding (FastMVU)
Kernel PCA
Generalized Discriminant Analysis (GDA)
Diffusion maps
Stochastic Neighbor Embedding (SNE)
Neighborhood Preserving Embedding (NPE)
Locality Preserving Projection (LPP)
Linear Local Tangent Space Alignment (LLTSA)
Stochastic Proximity Embedding (SPE)
Multilayer autoencoders (training by RBM + backpropagation or by an evolutionary algorithm)
Local Linear Coordination (LLC)
Manifold charting
Coordinated Factor Analysis (CFA)

This toolbox seems to no longer be available online. Do you have a copy you can share?
Thanks,
Søren
Hello Soren,
No I don't. I tried to contact Laurens but the e-mail address I have found on google does not seem to work.
Sorry,
Igor.
Yeah, that was my experience as well, which is a bit sad. All that hard work, and now the code is gone :-(
Thanks,
Søren
I am sure contacting one of his rrecent co-author might yield a more fruitful e-mail address.
Igor.
or through his linkedin profile.
Igor.
The LinkedIn stuff seems to require a paid membership of LinkedIn.
However, contacting co-authors sounds like a good idea. I'll try that.
Thanks,
Søren
The license allows for it, so I've posted a copy of v0.4b on my site:
http://www.andrew.cmu.edu/user/tebuck/drtoolbox.tar.gz
Thank you Taraz.
Igor.
I was just told that the new page is here:
http://ticc.uvt.nl/~lvdrmaaten/Laurens_van_der_Maaten/Home.html
ver. 0.7
I am going to update the post to reflect the new address.
Igor.
