Hi James,
It's a good idea. A JSON format is more convenient for visualization though a
little inconvenient to read. How about toJson() method? It might make the mllib
api inconsistent across models though.
You should probably create a JIRA for this.

Hi Anoop,
The Spark decision tree implementation supports: regression and multi class
classification, continuous and categorical features, pruning and does not
support missing features at present. You can probably think of it as
distributed CART though personally I always find the acronyms confusi
Hi Jake,
The "toString" method should print the full model in versions 1.1.x.
The current master branch has a method "toDebugString" for
DecisionTreeModel which should print out all the node classes and the
"toString" method has been updated to print the summary only so there is a
slight change i

@Aris, we are closely following the PMML work that is going on and as
Xiangrui mentioned, it might be easier to migrate models such as logistic
regression and then migrate trees. Some of the models get fairly large (as
pointed out by Sung Chung) with deep trees as building blocks and we might
have
st in boosting algos. We are eager to add them to
MLlib ASAP.

Hi Daniel,
Thanks a lot for your interest. Gradient boosting and AdaBoost algorithms
are under active development and should be a part of release 1.2.

Hi Justin,
I have created a JIRA ticket to keep track of your request. Thanks.

Hi Justin,
I am glad to know that trees are working well for you.
The trees will support minimum samples per node in a future release. Thanks
for the feedback.

Hi Suraj,
I can't answer 1) without knowing the data. However, the results for 2) are
surprising indeed. We have tested with a billion samples for regression
tasks so I am perplexed with the behavior.
Could you try the latest Spark master to see whether this problem goes
away. It has code that li
Sorry for arriving late to the party! Evan has clearly explained the
current implementation, our future plans and key differences with the
PLANET paper. I don't think I can add more to his comments. :-)
