1. Introduction

Overview of XGBoost

• XGBoost (eXtreme Gradient Boosting) is an advanced implementation of gradient boosting algorithm. It is a powerful machine learning technique for regression and classification problems.

2. Setting Up the Environment

Importing Libraries

# Python code to import necessary libraries
import xgboost as xgb
import numpy as np
import matplotlib.pyplot as plt
from sklearn.model_selection import train_test_split
from sklearn.datasets import load_iris

Loading the Dataset

# Python code to load a sample dataset
iris = load_iris()
X = iris.data
y = iris.target

3. Implementing XGBoost

Data Preparation

# Python code to split the data
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)

Model Training

# Python code to train the XGBoost model
model = xgb.XGBClassifier()
model.fit(X_train, y_train)

Model Evaluation

# Python code to evaluate the model
y_pred = model.predict(X_test)
