I'm pretty new to machine learning and I have a question regarding weighting features.

I was able to get code running with scikit-learn and random forest. Now I would like to weight certain features higher to give them more importance. The data ranges anywhere from T/F to dollar amounts. Can someone point me in a good direction for this? I haven't been very successful finding examples to use.

    $\begingroup$ Do you want to reweight the importance of predictive features, or predicted? $\endgroup$ – Sean Easter Mar 30 '17 at 0:47

Generally, it's not a great idea to try to meddle with feature weights - RF (and machine learning algorithms in general) works out the importance of features by itself.
