Dear Mohammadjavad,
This kind of questions are best directed to the scikit-learn mailing
list (and I am forwarding it there).
In this case, as the preimage is just the inverse transformation
between spaces, I don't think it would make much sense to use a
different kernel, so I guess it will be the
How can we combine probabilities from multiple classifiers in sklearn?
[Classifiers are trained on similar type datasets, difference being their
sizes and the way each result might be used]. I am using SGDClassifier to
train the individual classifiers, and need to choose the best amongst them.

Hi everyone,
I submitted a pull request to enable grid_search with failing
classifiers. Did anyone have some time to look at it?
Thanks,

It should at least be possible to use Adaboost with sparse matrices if the

Python has the built-in email package which could be useful for you at
least for the multipart stuff and the metadata.

Dear scikit-learn persons,
This is Pan Yi from the University of Washington, US. I am currently
working on a course project, exploring the performance of
AdaBoostClassifier when using the same base classifier, such as
DecisionTreeClassifier, Perceptron,
KNeighborsClassifier, or mixing different c
