Reg. the "Needs Review" tag - Could I request the maintainers to unlabel the PR once a review has been completed and is waiting for the author? (Should filter out a lot of noise). The use case I envision for this tag would be to serve as a bookmark or a green flag to the maintainer who labels it s

Thanks, Chris. I will look into your recommendations. I have tried artificial neural network and it was giving me good results on test set as well. Regards Waseem On Thu, Jun 23, 2016 at 12:00 PM, chris brew wrote: > It is probably a good idea to start by separating off part of your > training

It is probably a good idea to start by separating off part of your training data into a held-out development set that is not used for training, which you can use to create learning curves and estimate probable performance on unseen data. I really recommend Andrew Ng's machine learning course materi

Hi Brian, Thanks for your email, I did try tree.export_graphviz(model,out_file='tree.dot'),but I got an error saying AttributeError: 'RandomForestRegressor' object has no attribute 'tree_' which I think is because this is a forest, not a single tree that's why I can't visualise it, No? Also, do yo

Hi Muhammad, If you've not yet read the documentation I would highly recommend starting with the Decision Tree [1] and working your way through the examples on your own data. You'll find an example [2] of how to generate a graphviz compatible dot file and visualise it. Once your satisfied that y
