Post subject:  Decision forest in Python


I'm trying to get predictions from decision forest in Python using the attached script. The task is regression. I'm not sure if I'm using alglib correctly, because all of predictions are [0.0], even though avgerror and rmserror on test set are both < 0.1.

Specifically, what is x in dfprocessi - one data point, meaning a single row of attributes?

p = xalglib.dfprocessi( df, x )

Also, what should y be in dfprocess?

p = xalglib.dfprocess( df, x, y )
