Hi Sergey,
I am having the exact same issue with my data set except its 80 dimensional
and I only have two classes where the classes are unbalanced about 5:1. I
am also using random forest in sklearn. Just curious how well did using

I'm dealing with a 50-class classification problem with extremely
unbalanced classes. The smallest class has about 1000 samples and the
largest has 500,000. The random forest I've trained is being heavily
skewed towards the big classes.
Is there a good way to deal with this kind of problem in
Hi Sergey,
There is a sample_weights option (not very well documented) in the random
forest classifier that might help. You might want to check out the SVC example
to see the sample_weights format.

Thanks, Manish! Exactly what I was looking for.
