For more information and a list of typical modules available on this course, please read Data Science BSc in the course catalogue.

Year 1

In your first year of study, you’ll have the opportunity to learn a range of foundational topics that’ll serve as the basis for the rest of your studies.

In mathematics, you’ll cover topics such as linear algebra, calculus, statistics and probability. On the computational side, you’ll learn the basics of functional programming and software engineering, including data structures, parallelisation and effective algorithms for dealing with big data.

You'll also be exposed to basic principles of information theory, data visualisation, geographical information systems (GIS), natural language processing (NLP) and the social sciences foundations of interpersonal communication along with hands-on practical advice and practice.

These foundational concepts will provide the essential building blocks for data science, equipping you with the skills and knowledge necessary to understand more advanced topics as the course progresses.

Compulsory modules

Core Mathematics – 40 credits

This module introduces you to the fundamental topics in mathematics. You’ll learn the foundational concepts of function, number and proof, equipping you with the language and skills to tackle your mathematical studies. The module also consolidates basic calculus, extending it to more advanced techniques, such as functions of several variables. These techniques lead to methods for solving ordinary differential equations. Linear algebra provides a basis for wide areas of mathematics and this module provides the essential foundation.

Probability and Statistics – 20 credits

'Probability is basically common sense reduced to calculation; it makes us appreciate with exactitude what reasonable minds feel by a sort of instinct.' So said Laplace. In the modern scientific and technological world, it is even more important to understand probabilistic and statistical arguments. This module will introduce you to key ideas in both areas, with probability forming the theoretical basis for statistical tests and inference.

Computational Mathematics and Modelling – 20 credits

You'll be introduced to computational techniques, algorithms and numerical solutions, as well as the mathematics of discrete systems. You'll learn basic programming using the language Python and apply computational techniques to the solution of mathematical problems.

Data Science and Communication – 20 credits

This module examines the nature of data science, the data science lifecycle and the strategic organisational role of a data scientist. You’ll be introduced to a high-level approach to analysis of data in different formats and lays the foundation to work at the level of raw data, experimentation and reproducible programming pipelines. A key aspect is the interdisciplinary and integrated nature of the subject, in particular the social science dimension around communication, collaboration, design and ethics.

Modelling for Big Data – 20 credits

This module lays the foundations for computer programming for big data, with basics of procedural and functional programming, data structures and good programming practice such as reproducibility, collaborative editing and version control. You’ll encounter and practise techniques for handling big data such as parallelisation, vectorisation and high-performance computing, and for the design of efficient algorithms. These are applied to exploratory data analysis, computational modelling, problem solving, and data visualisation.

Year 2

Your second year will build on the first-year foundations, giving you more insight into applying data science in the ‘real world’. In mathematics, you’ll cover the basics of machine learning, such as clustering, principal component analysis, numerical methods, optimisation and neural networks. You'll also study networks and complex systems, analysing and visualising examples of real-world networks, as well as stochastic processes and statistical inference.

In computer science, you’ll learn more advanced topics such as object-oriented programming, distributed computing, software engineering, data mining and natural language processing. Furthermore, you’ll gain experience in the use of various tools and techniques for collecting, analysing and visualising data.

These topics will provide you with the essential building blocks for data science, equipping you with the understanding you’ll need to apply this discipline in industry.

Compulsory modules

Further Linear Algebra and Discrete Mathematics – 20 credits

Explore the more abstract ideas of vector spaces and linear transformations, together with introducing the area of discrete mathematics.

Machine Learning and Object-Oriented Programming – 20 credits

Develop your programming skills for applications to software engineering and machine learning. You'll encounter the object-oriented programming paradigm, as well as software engineering practices around design thinking, resource trade-offs and project management tools. Fundamental machine learning paradigms such as supervised, unsupervised and reinforcement learning are introduced and key topics in data science such as clustering, genetic algorithms, random forests and dimensionality reduction are also explored.

Stochastic Processes – 10 credits

A stochastic process refers to any quantity which changes randomly in time. The capacity of a reservoir, an individual’s level of no claims discount and the size of a population are all examples from the real world. The linking model for all these examples is the Markov process. With appropriate modifications, the Markov process can be extended to model stochastic processes which change over continuous time, not just at regularly spaced time points. You’ll explore the key features of stochastic processes and develop your understanding in areas like state, space and time, the Poisson process and the Markov property.

Time Series – 10 credits

In time series, measurements are made at a succession of times, and it is the dependence between measurements taken at different times which is important. This module will concentrate on techniques for model identification, parameter estimation, diagnostic checking and forecasting within the autoregressive moving average family of models and their extensions.

Graphs, Networks and Systems – 20 credits

You’ll be introduced to technical real-world considerations such as the analysis of networks and complex systems. The module builds on the mathematical foundations of algebra and graph theory and applies these to the analysis of networks. It compares and contrasts reductionism & superposition with non-linearity & complexity such as the messiness of the real world. Building on Computational Mathematics and Modelling, the module combines ideas of networks with non-linear activation functions in order to model the dynamics of basic neural networks and uses libraries to perform standard neural network tasks such as predictive modelling and classification.

Statistical Methods – 20 credits

Statistical models are important in many applications. They contain two main elements: a set of parameters with information of scientific interest and an "error distribution" representing random variation. This module lays the foundations for the analysis of such models. We’ll use practical examples from a variety of statistical applications to illustrate the ideas.

Optional modules (selection below indicative of typical options)

You’ll choose a total of 20 credits of optional modules that’ll help you tailor your knowledge to topics that interest you the most. These could be from the selection of options below or you could choose to combine your options with discovery modules.

Discovery modules give you the chance to apply your data science toolkit in real-world scenarios whilst expanding out into different areas, broadening your knowledge and giving you that competitive edge in the jobs market.

• Investigations in Mathematics – 10 credits
• Vector Calculus and Transforms – 20 credits

Year 3

Your third year will blend mathematics, computing and communication, using advanced concepts, tools and techniques to provide a deeper understanding of real-life data science.

You'll learn how to extract data from data bases for data mining, big data visualisation and artificial intelligence. A big component of the year will be a data science dissertation project alongside core data science modules and a range of optional modules in applied mathematics, statistics and discovery.

The dissertation project is your chance to apply everything you’ve learned to a real-world data science problem. Not only will you draw upon the technical knowledge learned throughout your degree, you’ll also use the advanced skills in areas like problem solving, strategic planning, analysis and visualisation to effectively tackle the challenges that arise in your project topic.

The exposure to an industry-relevant challenge is also a great first step in getting a taste for working in data science, building up industry experience before you graduate and demonstrating to employers your extensive skills in this field too.

Compulsory modules

Deep Learning and Explainable AI – 20 credits

This module builds on previous modules that cover Machine Learning and Neural Networks, and develops more advanced topics in areas like Artificial Intelligence and data mining, applied to key sectors such as finance, health, energy, sustainability etc. Key topics are Deep Learning and Explainable AI, for instance in the context of natural language processing, unstructured data labelling, object recognition and ethics. It reflects on the data science lifecycle in an organisational strategic context with a view to communicating insights and recommendations to institutional decision makers, achieving organisational goals, or effecting organisational change. The module thus aims to prepare you for applications of AI in professional industrial contexts.

Data Curation and Governance – 20 credits

Consider the practical aspects of working with real-world big data in a professional setting. It examines the need for data curation, quality and storage and explores appropriate tools such as databases and cloud technology. You’ll practise the important real-world task of data wrangling and curation through cleaning, processing and transformation and think about data from an organisational data modelling perspective. Professional settings also require an understanding of legal and ethical obligations surrounding e.g. privacy and data regulations/directives/compliance. This module therefore prepares you for the professional work environment.

Project in Data Science – 40 credits

You’ll receive training in research skills and develop and implement a personal training plan, conducting an independent research project in a topic in data science. You’ll meet in groups to discuss the project topic, with each team member researching a specific aspect of the topic, bringing back their findings to the group. You’ll produce an individual project report and give a group presentation of your work with each team member contributing.

Learning and teaching

Data science is all about being able to apply skills from communication, mathematics and computer science in a real-world context. This course follows input and guidance from employers, data science practitioners, researchers, teachers, students and graduates, combined with cutting-edge pedagogical research such as in the Leeds SCALA approach.

• Student-centred: Supportive, inclusive, flexible, accessible and community-building curricula. 
• Active learning: Cognitively involved students, who are engaged with diverse content and media, and have opportunities to collaborate & participate. 

Your learning will be blended, with a mix of campus-based and online activities alongside study resources. There will be lectures, seminars and problem-solving classes – specifically on the mathematical side – in order to give you the necessary technical proficiency in the foundations for rigorous data science analyses.

There will also be interactive workshops (‘hackathon’-style) to collaborate with your cohort and teaching staff in a very active, hands-on way (problem-based learning). Workshops aim to integrate concepts and tools from lectures in an authentic and motivating context, encouraging you to apply those learned skills in an interdisciplinary context to applications – just like in the real-world.

This also creates an inclusive environment where diversity is strength, and where we can all contribute and learn together as a tight-knit community.

On this course, you’ll be taught by our expert academics, from lecturers through to professors. You may also be taught by industry professionals with years of experience, as well as trained postgraduate researchers, connecting you to some of the brightest minds on campus.

Assessment

Assessments will give you the opportunity to engage and learn in a variety of ways, which is more representative of what real work is like. In fact, many assessments may also be a chance to build up your own portfolio to help with revision or to showcase your proficiency in the relevant data science tools and techniques to potential employers when you apply for jobs after you graduate.

Whilst exams remain a useful tool for assessing key technical ability – especially for mathematical modules – the course will focus on the ability to apply techniques and tools from mathematics, computing and communication in the context of data science applications. As such, you could also be assessed through a variety of diverse ways throughout the course including project work, report writing, presentations, case studies, group collaborations, videos, blog posts and a portfolio.
