Detail Description

1. Abstract

Virus Nucleotide Clustering is a Data Science project that focuses on grouping virus nucleotide data using the K-Means clustering algorithm. Since the dataset is unlabeled, unsupervised machine learning techniques are used to discover hidden patterns and relationships within the data. Clustering helps in organizing similar virus nucleotide sequences into groups based on their characteristics.

In this project, preprocessing techniques are applied to clean and prepare the dataset before model training. K-Means clustering is implemented to identify clusters within the nucleotide data. To improve computational efficiency and visualization, dimensionality reduction techniques such as Principal Component Analysis (PCA) and t-Distributed Stochastic Neighbor Embedding (t-SNE) are used. PCA reduces data dimensions while preserving important information, whereas t-SNE helps visualize clusters effectively in low-dimensional space. The project helps in understanding unsupervised learning, clustering algorithms, and dimensionality reduction techniques widely used in bioinformatics and data science.
