In this Byte, learn how to fit an XGBoost regressor and assess and calculate the importance of each individual feature, based on several importance types, and plot the results using Pandas in Python.

This post illustrates three ways to compute feature importance for the Random Forest algorithm using the scikit-learn package in Python. It covers built-in feature importance, the permutation method, and SHAP values, providing code examples.
Xgboost Built-in Feature Importance Let's start with importing packages. Please note that if you miss some package you can install it with pip (for example, pip install shap). import numpy as np import pandas as pd import shap from sklearn.datasets import load_boston from sklearn.model_sel...
