#### Course Description

In this course on Linear Algebra we look at what linear algebra is and how it relates to vectors and matrices. Then we look through what vectors and matrices are and how to work with them, including the knotty problem of eigenvalues and eigenvectors, and how to use these to solve problems. Finally we look at how to use these to do fun things with datasets - like how to rotate images of faces and how to extract eigenvectors to look at how the Pagerank algorithm works.Since we're aiming at data-driven applications, we'll be implementing some of these ideas in code, not just on pencil and paper. Towards the end of the course, you'll write code blocks and encounter Jupyter notebooks in Python, but don't worry, these will be quite short, focussed on the concepts, and will guide you through if you've not coded before.At the end of this course you will have an intuitive understanding of vectors and matrices that will help you bridge the gap into linear algebra problems, and how to apply these concepts to machine learning.

#### David Dye

David Dye is a Professor of Metallurgy in the Department of Materials. He develops alloys for jet engines, nuclear and caloric materials so as to reduce fuel burn and avoid in-service failure. This involves crystallography (vectors and transformation matrices) and techniques like neutron and synchrotron X-ray diffraction and electron microscopy at the atomic scale. These give rise to 'big data' analysis problems associated simply with the amounts of data we can now collect. His Phd and undergraduate degrees were from Cambridge University in 1997 and 2000; he joined Imperial in 2003. He also teaches introductory mathematics - errors and data analysis, and has won student-led awards for innovation in teaching.
