Post subject: | Decision forest in Python | ||
Hi, 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? Code: p = xalglib.dfprocessi( df, x ) Also, what should y be in dfprocess? Code: p = xalglib.dfprocess( df, x, y )
