[scikit-learn] Random Forest with Mean Absolute Error

2016-10-23 Thread Robert Slater
I searched the archives to see if this was a known issue, but could not seem to find anyone else having the problem. Nevertheless, in the latest version (0.18) Random Forest Regressor has the new option of 'mae' for criterion. However it appears to run disporportinally longer than the 'mse' crite

You definitely can use some of the tools in sci-kit learn for supervised machine learning. The real trick will be how well your training system is representative of your future predictions. All of the various regression algorithms would be of some value and you make even consider an ensemble to h

I think your use of "X" in X_mod should be "X_train" instead, as X_mod is currently using unshuffled indices while X_check uses the shuffled indices. Virus-free. www.avast.co
