Abstract:
Linear Algebra is the branch of mathematics that deals with scalars, vectors, and matrices. The main motivation behind developing linear algebra was to solve the system of linear equations. Linear equations represent the basic objects in geometry such as lines and planes. Thus solving the system of linear equations computes the intersection of planes and lines. It is applied in physics and engineering to model many natural phenomena and calculate their efficiency. Linear algebra also plays an important role in Data Science. Data Science is the interdisciplinary field that deals with extracting meaningful insights from data using machine learning algorithms and computational techniques. Linear Algebra provides a mathematical framework to represent , understand , manipulate and obtain information from the data.It is also used in machine learning algorithms for prediction , classification and optimization.Linear algebra is foundational to data science, providing the tools for working with data in high-dimensional spaces, making complex data transformations, and optimizing machine learning algorithms. Linear algebra techniques are used for dimension reduction and recommendation systems. Data presentation and manipulation using vectors and matrix operations in Linear algebra. Principal component analysis(PCA) is a widely used technique to reduce the dimension of the data which uses the eigenvalue and eigenvectors in Linear Algebra. Natural Language process ( NLP) is one of the important areas of Data science which focuses on human and computer interaction. Linear Algebra provides a platform to represent , analyze and transform textual information in NLP. NLP models use Linear Algebra to process and understand natural language efficiently. In Data science, image processing and computer vision is used to extract ,interpret and analyze information from visual data. Linear algebra plays a key role in image processing and computer vision systems to obtain information in visual data . This paper focuses on such applications of Linear algebra in Data Science especially in machine learning algorithms, NLP, image processing and computer vision .
Key words: Linear Algebra, Data Science, Machine learning, Dimension reduction , image procession, computer vision
