### House price inflation modelling

I have a data set of house prices and their corresponding features (rooms, meter squared, etc). An additional feature is the sold date of the house. The aim is to create a model that can estimate the ...

### Does Gradient Boosting perform n-ary splits where n > 2?

I wonder whether algorithms such as GBM, XGBoost, CatBoost, and LightGBM perform more than two splits at a node in the decision trees? Can a node be split into 3 or more branches instead of merely ...

### DecisionTreeRegressor under the hood of GradientBoostingClassifier

I'm inspecting the weak estimators of my GradientBoostingClassifier model. This model was fit on a binary class dataset. I noticed that all the weak estimators under this ensemble classifier are ...

### Which other algorithms fit residuals like XGBoost? [closed]

XGBoost and standard gradient boosting train learners to fit the residuals rather than the observations themselves. I understand that this aspect of the algorithm matches the boosting mechanism which ...

### Output value of a gradient boosting decision tree node that has just a single example in it

The general gradient boosting algorithm for tree-based classifiers is as follows: Input: training set $\{(x_{i},y_{i})\}_{i=1}^{n}$, a differentiable loss function $L(y,F(x))$, and a number of ...

### Can Boosted Trees predict below the minimum value of the training label?

I am using gradient Gradient Boosted Trees (with Catboost) for a Regression task. Can GBtrees predict a label that is below the minimum (or above the max) that was seen in the training ? For instance ...

### Why would GradientBoostClassifier do better than XGBoostClassifier? [duplicate]

I am working on the Kaggle home loan model and interestingly enough, the GradientBoostClassifier has a considerably better score than XGBClassifier. At the same time it seems to not overfit as much. (...
