Abstract :
This article offers a comprehensive introduction to the key concepts of unsupervised machine learning, a type of
machine learning where models are trained using data that has not been labeled or categorized. The primary goal of
unsupervised learning is to identify hidden patterns or structures within the data without the need for predefined labels. It
explores various unsupervised learning techniques, such as clustering, dimensionality reduction, and anomaly detection,
highlighting their potential applications in fields like data mining, pattern recognition, and market segmentation. In
addition to the theoretical framework, the article delves into a practical example by focusing on one of the most commonly
used unsupervised learning algorithms: k-means clustering. The k-means algorithm is a popular method for partitioning
data into distinct groups (clusters) based on similarities. It is especially useful for discovering patterns in large datasets,
where the objective is to assign data points to clusters based on their proximity to a centroids. The article further
demonstrates the implementation of this algorithm within the GAMS (General Algebraic Modeling System) environment,
showing how it can be used to perform clustering tasks and interpret the results within a computational framework
designed for optimization and mathematical modeling. This hands-on example serves as a practical guide for readers
looking to apply unsupervised machine learning techniques to real-world problems.
