Thanks for the help, guys. Indeed it's easy enough to implement a class for combining the classifiers in a model-specific way. Thanks for the note on the oob-score! On Thu, Jan 10, 2013 at 2:28 AM, Olivier Grisel wrote: > 2013/1/10 Gael Varoquaux : > > On Thu, Jan 10, 2013 at 03:57:23PM +1100,

[Scikit-learn-general] Size of random forest model

2013-01-08 Thread David Broyles
Hi, I'm pretty new to scikit-learn. I've generated a random forest (classification) of 100 trees using default attributes. My data set has over 2M examples. 2 questions: 1) I've noticed the size of the pickled model is quite large (e.g. ~9GB). A comparable model trained with R's randomForest

Hi, I'm new to scikit-learn. Curious if there's a way to combine forests trained separately, similar to the combine() method in the R randomForest package. Thanks in advance! David -- Master Visual Studio, SharePoint, S
