1.1 Problem Statement

1. INTRODUCTION

Development of a machine learning-based framework for DNA sequence analysis to address three major challenges in genomics: identification of species, detection of promoter regions, and classification of DNA sequences.

Genomic data analysis plays a pivotal role in understanding the intricate biological processes encoded within DNA. As researchers delve into the genetic codes of organisms, they uncover valuable insights into genetic predispositions, disease mechanisms, evolutionary trends, and much more. The advancement of sequencing technologies, particularly Next-Generation Sequencing (NGS), has revolutionized this field, enabling the efficient sequencing of entire genomes, transcriptomes, and epigenomes. These innovations have resulted in massive datasets, necessitating the use of computational methods to process, analyze, and interpret the data effectively.

2. Objectives

The integration of machine learning (ML) techniques has emerged as a powerful tool for extracting meaningful patterns and making predictions from these complex datasets. Machine learning methods, such as supervised learning, unsupervised learning, and deep learning, allow researchers to identify genetic variations, classify species, and predict disease risks, providing insights that were previously unattainable. From gene expression analysis to the detection of genetic biomarkers for diseases, machine learning models help unravel the vast potential of genomic data.
