I'm tryin to do regression with extraTrees, however it's not obvious how to define more than one value for the output for each input. I could not find an example. It this feature available ?

It is possible put only through tasks variable:

If you have two dimensional output then for each x that has both values you have to duplicate their rows in the input matrix
and set tasks value of the first row equal to 1
and tasks value of the second row to 2.
And in the y you then record each dimension value for them (1st dimension for first row and 2nd dimension for the next row).
