Dimensionality Reduction #13

Open lpatiny opened 9 years ago

lpatiny commented 9 years ago

Would be nice to have the following methods

[x] PCA - ml-pca
[x] Singular Value Decomposition (SVD) - ml-matrix
[x] Eigen Decomposition - ml-matrix
[ ] Non-negative Matrix Factorization (NMF)
[ ] tSNE
[ ] Independent Component Analysis (ICA)
[ ] Random Projection
[ ] Factor Analysis (FA)
[ ] umap

NMF could be interesting because there are a lot of applications (in dimensionality reduction and clustering). I'll implement it.

may I suggest

tSNE

http://scienceai.github.io/tsne-js/ . (I use this one in my blocks https://bl.ocks.org/Fil/2dc296af097cd26242b52105e06763d8)

umap

https://github.com/lmcinnes/umap (python only atm)

Interesting, thanks you for your suggestion

Just wanted to link to a javascript umap implementation here: umap-js. Keep in mind there's a few features missing from the python implementation, but the performance is reasonable all things considered.
