A plain Principal Component Analysis algorithm was added in https://github.com/rust-ml/linfa/commit/7b6075e2dc9cc1c56ad7cd956bf996d69ce51d20. The next steps should improve upon edge-cases and features…

You mentioned in the README that the R implementation is slow due to the use of the `prcomp` function.
Have you taken a look at the [irlba](https://cran.r-project.org/web/packages/irlba/index.html) p…

It looks like the function ac.tl.lsi is mostly just a call to `scipy.sparse.linalg.svds`.

I am not sure if there's a solution, much less one that could happen at the unconf. If it's just a lament, we can close this and move on. But the discussion on #69 has this on my mind and maybe some…

For multiple genomic data, most of the information can be stored as matrices. The most striking example is with SNP data, which can be stored as matrices with thousands to hundreds of thousands of row…

#### Description
Hi developers,
There's a sklearn model called [SparsePCA](https://scikit-learn.org/stable/modules/generated/sklearn.decomposition.SparsePCA.html), but it doesn't seem to be SPCA a…

**Objective**
Develop an efficient method to compute the statistics s(c) for a given non-linear n-dimensional function f(x, y) with dependent variables x and y, such that F(f(s(x), s(y))) = s(c) whil…

This function calculated all the eigen pairs.
Calculating only few e…

`B_full = M * B_reduced`
example: MNLogit reduced to stereotype Logit, `slogit` in Stata
but this also has the same structure as cointegrating regression (VAR).
see slogit references, and similar m…
