1. Introduction

Overview of DBSCAN

• DBSCAN is a density-based clustering algorithm that identifies clusters as high-density regions separated by regions of low density. It's particularly effective for identifying outliers and handling irregularly shaped clusters.

2. Setting Up the Environment

Importing Libraries

# Python code to import necessary libraries
import numpy as np
import matplotlib.pyplot as plt
from sklearn.cluster import DBSCAN
from sklearn.datasets import make_moons

Generating the Dataset

# Python code to generate a sample dataset with a non-trivial structure
X, _ = make_moons(n_samples=300, noise=0.05, random_state=0)

3. Implementing DBSCAN

Data Preparation

• No target variable is needed as DBSCAN is an unsupervised algorithm.

Model Training

# Python code to train the DBSCAN model
dbscan = DBSCAN(eps=0.3, min_samples=10)
dbscan.fit(X)

Identifying Clusters

• Clusters can be identified from the labels assigned by the DBSCAN model.
