Hmm... and on windows 7 ~ (do you want specific build details?) The ExtraForestClassifier with 10 trees (the default) crashes and gives this: http://i.imgur.com/7hLyM.png .. don't think this happened on ubuntu 12.10? On 3 December 2012 00:41, Ronnie Ghose wrote: > hmm interesting it se

hmm interesting it seems that using only low level svms it worked this time.. but broke on LabelSpreading. Also please uncomment the higher degree SVM's I think those are the ones that tend to crash. let me test again also. ... and I forgot to use ones with the poly kernel ... I think that's the pr

oh hmm so if anyone wants to suggest additions to the script i'm all for it. it's a horrible mess :) and i didn't have any success in running the classifiers in parallel. ironically due to what i thought was an error caused by it (which i now find to be the svm). ... besides things like feature sca

The data is *not* scaled. Though it makes svm happy and make everything better. it makes me lose data and I don't need it in this case. On 2 December 2012 11:55, Olivier Grisel wrote: > Maybe also check that the data is scaled to unit variance (or maybe > take the sqrt or log of it if it's pos

Maybe also check that the data is scaled to unit variance (or maybe take the sqrt or log of it if it's positive and spans several orders of magnitudes). -- Keep yourself connected to Go Parallel: DESIGN Expert tips on st

Um.. 1 feature.. 2 data points. so it should be trivial for it no? (besides the time and the nice quadratic complexity spoken of). Nope on this vm there's 30 gb. I'm using at max like 10 ish? On 2 December 2012 03:59, Andreas Mueller wrote: > On 12/02/2012 08:44 AM, Ronnie Ghose wrote: > >

So somehow while running an SVM model i'm getting a nice seg fault :(. http://pastie.org/5465679 is the last 50 lines of the strace file. in specific it seems to be SVM with poly setting and degree=10. I'm running it in 2 numbers... then I tried to lower it to 1000 and still got seg fault
