Predicting Bike Rentals - DT/RF not better than LR

Dear all,

Link to my Notebook

I’m struggling with my results from this guided project, even after checking the solution. I get better results by using Linear Regression than by using DTs or RFs - no matter the combination of my features

Maybe I’ve chosen a poor selection of features? Or maybe my hyperparameters are not ideal?
(Please check the plot at the end of the notebook)

I would really appreciate any input/suggesiton

Thank you
Best Regards
Daniel Burnier
