[Scikit-learn-general] PCA nipals and Sparse PCA

Hi, Just to summarize the situation and to avoid confusion. There are mainly two things where I was focusing my attention. 1 - Nipals PCA ( http://en.wikipedia.org/wiki/Principal_component_analysis#The_NIPALS_method ) This is a good alternative to SVD and it is much faster in situations where

IIRC, weekly post are not a GSoC requirement but they are a _PSF_ requirement, and since scikit-learn is participating to GSoC under the PSF umbrella, the requirement applies to us. I think it's great incentive to think of your work in terms of what you could show to others. No matter how

[Scikit-learn-general] Storing the values of internal nodes in DecisionTrees

2014-06-01 Thread John Prior
Hello, In the past I've found it extremely useful to inspect internal (non-leaf) nodes of sklearn DecisionTrees (especially the root nodes). However, at some point a small code optimization was made and now values of internal nodes are no longer stored: you can see the code that avoids storing
