Hi Alessandro,
I think absolute error as splitting criterion
Hi Alessandro,
MLlib v1.1 supports variance for regression and gini impurity and entropy
for classification.

If the information gain calculation can be performed by distributed
aggregation then it might be possible to plug it into the
guarantees.

By the looks of it, the GradientBoosting API would support an absolute
error type loss function to perform quantile regression, except for weak
hypothesis weights. Does this refer to the weights of the leaves of the
trees?

I am currently using the RDD aggregate operation to reduce (fold) per
partition and then combine using the RDD aggregate operation.
def aggregate[U: ClassTag](zeroValue: U)(seqOp: (U, T) = U, combOp: (U, U)
= U): U
I need to perform a transform operation after the seqOp and before the
combOp. The
