• MA-M06 Mathematics for Data Science

  The module provides a basic introduction to mathematical foundations for data science and machine learning. It covers essential concepts from linear algebra and calculus that are of direct utility to analysis of large data sets. The module includes basic problems in one-dimensional Calculus and Linear Algebra that illustrate concepts of differentiation and integration of functions of one variable, operations with matrices and methods for solving linear systems of equations. It also highlights the use of Python in the numerical solution of these problems, as well as in symbolic computation.

• MA-M07 Further Mathematics for Data Science

  The module develops mathematical foundations for data science and machine learning. The module covers basic problems of Vector Calculus, Linear Algebra and Optimization including concepts of partial derivatives, gradient and Hessian, eigenvalues and eigenvectors of matrices and their use in optimisation problems, method of gradient descent and its application in Machine Learning. It also highlights the use of Python in the numerical solution of these problems, as well as in symbolic computation.
