Data Science: DBSCAN Clustering using Python
DBSCAN clustering is a widely used algorithm for grouping data points based on their density. It offers several advantages, such as being robust to noise, handling clusters of different shapes and sizes, and not requiring data normalization. However, DBSCAN clustering also has its limitations, such as requiring tuning of parameters, being sensitive to the density parameter, and struggling with high-dimensional data. In this article, we will provide a step-by-step guide to implementing DBSCAN clustering on a dataset using Python. We will cover generating random data, creating a Pandas dataframe, checking and filling missing data, scaling and normalizing the data, reducing the dimensionality of the dataset, performing DBSCAN clustering, assigning cluster colors, visualizing clusters, and exporting the clustered data with cluster labels to a CSV file.
