hi all, Please I need help on two things: First where to learn/ improve my python skills and secondly how to apply scikit-learn to pin point/ extract features that are similar in all my data sets Raphael On 2 November 2014 21:52, Andy wrote: > Why doesn't it help you? > And why do you want

Why doesn't it help you? And why do you want to port an SVM? So this is more of a coding exercise? There is a blog-post by Mathieu on implementing SVMs using CVXOPT (http://www.mblondel.org/journal/2010/09/19/support-vector-machines-in-python/) and there are some more educational implementations f

Regarding to SVM, I don't know why that SVM in Scikit-Learn is running very slow and I cannot even have the results.. On Sat, Nov 1, 2014 at 2:46 PM, Sturla Molden wrote: > On 01/11/14 12:16, Philipp Schiffer wrote: > > > Would someone maybe know of a good tutorial, which could help porting a >

Hi everybody! Would someone maybe know of a good tutorial, which could help porting a SVM written in Matlab to Python and Scikit-learn? I am more or less fluent in Python, but not yet in machine learning approaches. I do however have this Matlab script which fits to my data (various protein an
