Part III

Students select five taught modules in total, distributed across Michaelmas and Lent terms. Students should select no more than four modules from those offered in Michaelmas and no more than two modules from those offered in Lent. A module that starts in Michaelmas term and continues in Lent term will count as a single module. The taught modules are delivered in a range of styles and have a variety of assessment methods. For example: traditional Lecture-based modules which have the prefix 'L' such as 'L11 Algebraic path problems'; modules with a large proportion of Practical classes have the prefix 'P' such as 'P51 High performance networking'; and Reading clubs or seminar style modules have the prefix 'R' such as 'R254 Cybercrime'.

Please check the lecture timetables for timetable details.

  • Advanced Topics in Computer Architecture (R265) – Prof Simon Moore, Dr Robert Mullins, Dr Jonathan Woodruff – 16 h

    This course aims to provide students with an introduction to a range of advanced topics in computer architecture. It will explore the current and future challenges facing the architects of modern computers. These will also be used to illustrate the many different influences and trade-offs involved in computer architecture.

  • Advanced topics in programming languages (R277) – Dr Jeremy Yallop – 16 h

    This module explores various topics in programming languages beyond the scope of undergraduate courses. It aims to introduce students to ideas, results and techniques found in the literature and prepare them for research in the field.

  • Affective Artificial Intelligence (L344) – Prof Hatice Gunes – 16 h

    Affective Artificial Intelligence (Affective AI) aims to imbue machines with social and emotional intelligence (EQ). More specifically, Affective AI aims to create artificially intelligent systems and machines that can recognize, interpret, process, and simulate human social signals and behaviours, expressions, and emotions, to enhance human-AI interaction and communication. To achieve this goal, Affective AI draws upon various scientific disciplines, including machine learning, computer vision, speech / natural language / signal processing, psychology and cognitive science, and ethics and social sciences.

  • Category Theory (L308) – Prof Marcelo Fiore – 16 h

    Category theory provides a unified treatment of mathematical properties and constructions that can be expressed in terms of “morphisms” between structures. It gives a precise framework for comparing one branch of mathematics (organized as a category) with another and for the transfer of problems in one area to another. Since its origins in the 1940s motivated by connections between algebra and geometry, category theory has been applied to diverse fields, including computer science, logic and linguistics. This course introduces the basic notions of category theory: adjunction, natural transformation, functor and category. We will use category theory to organize and develop the kinds of structure that arise in models and semantics for logics and programming languages.

  • Computer Security: Principles and Foundations (R209) – Prof Robert Watson, Dr Alice Hutchings, Prof Alastair Beresford, Dr Martin Kleppmann – 16 h

    This course aims to give students an introduction to the history and central themes of computer security, from its 1970s foundations to some current research topics, with a theme of how to defend cloud-based systems against capable motivated opponents.

  • Digital Money and Decentralised Finance (R160) – Prof Frank Stajano, Dr Ferdinando Samaria – 16 h

    Our society is evolving towards digital payments and the elimination of physical cash. Digital alternatives to cash require trade-offs between various properties including unforgeability, traceability, divisibility, transferability without intermediaries, privacy, redeemability, control over the money supply and many more, often in conflict with each other. Since the 1980s, cryptographers have proposed a variety of clever technical solutions addressing some of these issues but it is only with the appearance of Bitcoin, blockchain and a plethora of copycat cryptocurrencies that a new asset class has now emerged, worth in excess of two trillion dollars (although plagued by extreme volatility). Meanwhile, most major countries have been planning the introduction of Central Bank Digital Currencies in an attempt to retain control. This seminar-style interactive module encourages the students to understand what's happening, what the underlying problems and opportunities are (technical, social and economic) and where we should go from here. We are at a historical turning point where an enterprising candidate might disrupt the status quo and truly make a difference.

  • Digital Signal Processing (L314) – Dr Markus Kuhn – 16 h

    This course teaches basic signal-processing principles necessary to understand many modern high-tech systems, with examples from audio processing, image coding, radio communication, radar, and software-defined radio. Students will gain practical experience from numerical experiments in programming assignments (in Julia, MATLAB or NumPy).

  • Homotopy Type Theory & Univalent Foundations (L313) – Dr Jon Sterling – 16 h

    Homotopy type theory/univalent foundations is a new foundations for general mathematics in which equality is relaxed to include symmetry, and sets arise as a special case of infinite-dimensional structures called homotopy types. This course introduces the basic notions of univalent foundations (dependent types, identity types, equivalences, truncation levels, the univalence axiom, classifying types, and fundamental groups). After taking this course, a student would be able to read and participate in the current discourse on the frontiers of univalent foundations.

  • Introduction to Computational Semantics (L98) – Dr Weiwei Sun, Prof Simone Teufel – 16 h

  • Large-scale data processing and optimisation (R244) – Dr Eiko Yoneki – 16 h

    This module provides an introduction to large-scale data processing, optimisation, and the impact on computer system's architecture. Large-scale distributed applications with high volume data processing such as training of machine learning will grow ever more in importance. Integrating machine learning approaches (e.g. Bayesian Optimisation, Reinforcement Learning) for system optimisation will be also explored in this course.

  • Machine Learning and the Physical World (L48) – Dr Carl Henrik Ek – 16 h

    The module “Machine Learning and the Physical World” is focused on machine learning systems that interact directly with the real world. Building artificial systems that interact with the physical world have significantly different challenges compared to the purely digital domain. In the real world data is scares, often uncertain and decisions can have costly and irreversible consequences. However, we also have the benefit of centuries of scientific knowledge that we can draw from. This module will provide the methodological background to machine learning applied in this scenario. We will study how we can build models with a principled treatment of uncertainty, allowing us to leverage prior knowledge and provide decisions that can be interrogated.

  • Machine Learning for Language Processing (L101) – Prof Andreas Vlachos – 16 h

  • Advanced Topics in Category Theory (L118) – Prof Jamie Vicary – 16 h

    The module will introduce advanced topics in category theory. The aim is to train students to engage and start modern research on the mathematical foundations of higher categories, the graphical calculus, monoids and representations, type theories, and their applications in theoretical computer science, both classical and quantum.

  • Computing for Collective Intelligence (R181) – Prof Amanda Prorok – 16 h

    There is a substantial body of academic work demonstrating that complex life is built by cooperation across scales: collections of genes cooperate to produce organisms, cells cooperate to produce multi-cellular organisms and multicellular animals cooperate to form complex social groups. Arguably, all intelligence is collective intelligence. Yet, to-date, many artificially intelligent agents (both embodied and virtual), are generally not conceived from the ground up to interact with other intelligent agents (be it machines or humans). The canonical AI problem is that of a monolithic and solitary machine confronting a non-social environment. This course aims to balance this trend by (i) equipping students with conceptual and practical knowledge on collective intelligence from a computational standpoint, and (ii) by conveying various computational paradigms by which collective intelligence can be modelled as well as synthesized.

  • Cryptography and Protocol Engineering (P79) – Dr Martin Kleppmann, Dr Daniel Hugenroth – 16 h

    We all use cryptographic protocols every day: whenever we access an https:// website or send a message via WhatsApp or Signal, for example. In this module, students will get hands-on experience of how those protocols are implemented. We start by writing our own secure messaging protocol from scratch, and then move on to more advanced examples of cryptographic protocols for security and privacy, such as private information retrieval (searching for data without revealing what you’re searching for).

  • Cybercrime (R354) – Dr Alice Hutchings, Dr Richard Clayton, Jack Hughes – 16 h

    This module examines major topics relating to cybercrime from an interdisciplinary perspective. These include offense types and techniques, targets, victimisation, social and financial cost, criminal marketplaces, offenders, detection and prevention, and regulation and policing. The module outlines: Key debates in cybercrime research; how crime is committed using computer systems; and provides an understanding of how cybercrime is regulated, policed, detected and prevented.

  • Explainable Artificial Intelligence (L193) – Prof Mateja Jamnik, Mateo Espinosa Zarlenga, Dr Zohreh Shams – 16 h

    The recent palpable introduction of Artificial Intelligence (AI) models to everyday consumer-facing products, services, and tools brings forth several new technical challenges and ethical considerations. Amongst these is the fact that most of these models are driven by Deep Neural Networks (DNNs), models that, although extremely expressive and useful, are notoriously complex and opaque. This “black-box” nature of DNNs limits their ability to be successfully deployed in critical scenarios such as those in healthcare and law. Explainable Artificial Intelligence (XAI) is a fast-moving subfield of AI that aims to circumvent this crucial limitation of DNNs by either (i) constructing human-understandable explanations for their predictions, or (ii) designing novel neural architectures that are interpretable by construction.

  • Geometric Deep Learning (L65) – Prof Pietro Lio', Dr Petar Veličković – 16 h

    This module will study geometric deep learning -- machine learning approaches on nontrivially-structured data. It aims to provide students with the capability to analyse such data in an effective way, position geometric deep learning in a proper context with related fields, and enable students to contribute to this emerging area in future years. Specifically, it will highlight graph structures as an elegant abstraction that can be used to represent a wide variety of deep learning approaches, and there will be a corresponding focus on graph neural network architectures. The module will be grounded in theoretical concepts of invariance, equivariance, symmetries and network science, offering a sufficiently broad lens to tackle generic geometric deep learning setups (over grids, groups and manifolds---not only graphs).

  • Mobile Health (L349) – Prof Cecilia Mascolo, Dr Jing Han – 16 h

  • Multicore Semantics and Programming (L304) – Prof Peter Sewell, Dr Timothy Harris, Dr Christopher Pulte – 16 h

    In recent years multiprocessors have become ubiquitous, but building reliable concurrent systems with good performance remains very challenging. This module introduces some of the theory and the practice of concurrent programming, from hardware memory models and the design of high-level programming languages to the correctness and performance properties of concurrent algorithms.

  • Principles of AI-driven Neuroscience and Explainability (L205) – Prof Pietro Lio', Michail Mamalakis, Dr Tiago Azevedo – 16 h

    This module aims to provide students with a comprehensive understanding of graph neural networks, selected geometric deep learning models, convolutional neural networks (CNNs), transformers, and fundamental concepts of brain anatomy, connectomes, and medical imaging. A particular emphasis is placed on explainability and interpretability in the medical domain, specifically neuroscience.

  • Principles of Machine Learning Systems (L46) – Prof Nic Lane, Dr Titouan Parcollet – 16 h

    This course will examine the emerging principles and methodologies that underpin scalable and efficient machine learning systems. Primarily, the course will focus on an exciting cross-section of algorithms and system techniques that are used to support the training and inference of machine learning models under a spectrum of computing systems that range from constrained embedded systems up to large-scale distributed systems. It will also touch up the new engineering practices that are developing in support of such systems at scale.
