The gradient boosted trees models in Darts (XGBoost, CatBoost and LightGBM) all allow you to enforce a monotonic relationship between a feature/covariate and the target. This can be quite useful in ca…

## Motivation
Linear trees represent a practical technique that not only enhances model performance a…

In the same line of thought of algorithms which claim... or have beaten deep learning methods (Issue 144), Gradient Boosted Trees is one of them.

Hi,
I am trying to build a standard pipeline for tabular data that works nicely with ONNX. Ideally, the pipeline would:
1. Be based on boosted trees
2. Gracefully support mixed types (categoric…

Hi all,
I am a newbie in Shap, so
sorry to disturb!
I am exploring a way to parse a Xgboost model dump to memory to then be able to use it with TreeSHAP.
This is my first approach in explaining t…

While pandas supports a column with mixed ints/ floats which are nan, tc does not identify float("nan") as None and thus Xgboost failed on data converted from pandas.
```
import pandas as pd

Hi, I'm running a simple Boosted Tree Classifier on a dataset that has 5 features.
It seems to run fine for small datasets (up to 50k entries), however, once I start to get to 100k and up it begin…

I noticed that the leaf nodes in decision trees only contain a single response value, as seen in this example: https://github.com/oneapi-src/oneDAL/blob/bbe13a4bcaca8eabd3751b0ccf58ed9a044254f9/cpp/da…
