This unit will involve practical system creation or experimentation work in an area of computing other than digital media. The curriculum is specific to the project you choose but it will include seminars on skills and techniques required for successful design and implementation of research resources, time management, research presentation (oral, written, posters) and professional, legal and ethical issues in computing. Examination of a case study or project in an area appropriate to your intended dissertation work. Where appropriate, the implementation or experimentation may be work-based.

Introduction to Data Science
Introduces concepts, techniques and algorithms for processing and visualising datasets so as to infer useful, actionable knowledge in a domain. The unit develops skills which allow appropriate selection and application of data visualisation techniques for probing and obtaining insights into the nature and the structure of datasets so as to identify and report useful and interesting relationships. A variety of data mining algorithms will be explored with an emphasis on selecting the most suitable for particular data science goals. Students will be able to interpret and explain the data and the models obtained from a data science process, as well as communicate those effectively to stakeholders and make judgements on the use of the data informed by ethical, legal and society issues and implications.
