WebYes decision tree is able to handle both numerical and categorical data. Which holds true for theoretical part, but during implementation, you should try either OrdinalEncoder or one-hot-encoding for the categorical features before training or testing the model. Always remember that ml models don't understand anything other than Numbers. Share WebUnlike fitting a single large decision tree to the data, which amounts to fitting the data hard and potentially overfitting, the boosting approach instead learns slowly. Given the current model, you fit a decision tree to the residuals from the model.
