Michaelmas term

  • Advanced Computer Design (P34) – Prof Simon Moore – 16 h

    The aim of this module is to provide an introduction to undertaking multithreaded multiprocessor computer architecture research using FPGAs as an emulation platform.

  • Advanced Operating Systems (L41) – Dr Robert Watson – 16 h

    Operating systems are complex, concurrent, and rapidly evolving software systems: the process model, hardware abstraction, storage and networking services, security primitives, and tracing/analysis/debugging tools are a critical foundation for our contemporary computing environments. This course teaches a blend of operating-system design and implementation as well as systems research methodology through a series of lectures and practical material split into four two-week sub-modules. The first introduced tracing, profiling, and performance analysis techniques. The remaining three sub-modules will apply these skills to critical parts of our systems stack corpus: local filesystems/storage, the network stack/protocols, and distributed filesystems (not yet a final list). Measurement and evaluation will be a core aspect of the module: through labs and practical exercises, students will gain a deeper understanding of core principles in system behaviour, as well as analysis skills and intuitions that will serve them in future systems research. Lectures will consider methodology, systems principles, and systems implementation. There will likely be 1-2 guest lectures from experts in the field.

  • Algebraic Path Problems, with applications to Internet Routing (L11) – Dr Timothy Griffin – 16 h

    A great deal of interesting work was done in the 1970s in generalizing shortest path algorithms to a wide class of semirings – called “path algebras” or “dioids”. Although the evolution of Internet Routing protocols does not seem to have taken much inspiration from this work, recent “reverse engineering” efforts have demonstrated that an algebraic approach is very useful for both understanding existing protocols and for exploring the design space of future Internet routing protocols. This course is intended to present the basic mathematics needed to understand this approach. No previous background will be assumed. The course will start from scratch and end with open research problems. Many examples inspired by Internet Routing will be presented along the way.

  • Automated Reasoning (L18) – Dr Mateja Jamnik – 16 h

    Provides an introduction to how reasoning can be automated from an AI perspective. The course will introduce students to fundamental techniques for designing and implementing automated reasoners, and present advanced uses of theorem proving for solving mathematical problems via automated reasoning.

  • Building an Internet Router (P33) – Dr Andrew Moore – 16 h

    This module requires the full design, implementation, testing and inter-operability of a complex hardware and software system.

  • Category Theory and Logic (L108) – Prof Andrew Pitts – 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.

  • Chip Multiprocessors (R05) – Dr Robert Mullins – 16 h

    Uni-processor designs can no longer be scaled to take full advantage of advances in fabrication technology. This has forced a shift to parallel architectures in an attempt to sustain performance growth. This module examines the motivation for such a shift in detail, and covers the research challenges facing industry and academia in attempting to exploit single-chip parallel architectures.

  • Computer Security: Principles and Foundations (R209) – Dr Robert Watson, Prof Ross Anderson, Daniel Thomas – 16 h

    This course aims to provide students with 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. The course considers first local computer systems and then distributed systems; however, we will rapidly discover that this is an artificial distinction that only becomes more awkward as we enter the current period. Throughout the course, we will consider proposed systems along with the adversarial research intended to identify gaps and vulnerabilities.

  • Computer Vision and Robotics (E4F12) – Prof Roberto Cipolla – 16 h

    NB: Module offered by the Department of Engineering. The module aims to introduce the principles, models and applications of computer vision. The course will cover image structure, projection, stereo vision, and the interpretation of visual motion. It will be illustrated with case studies of industrial (robotic) applications of computer vision, including visual navigation for autonomous robots, robot hand-eye coordination and novel man-machine interfaces.

  • Data Centric Systems and Networking (R212) – Dr Eiko Yoneki – 16 h

    This module provides an introduction to data centric systems and networking, where data is a token in programming flow and networking and its impact on the computer system's architecture. Large-scale distributed applications with big data processing will grow ever more in importance and become a pervasive aspect of the lives of millions of users. Supporting the design and implementation of robust, secure, and heterogeneous large-scale distributed systems is essential.

  • Introduction to Natural Language Syntax and Parsing (L95) – Prof Ted Briscoe, Dr Stephen Clark – 16 h

    This module aims to provide a brief introduction to linguistics for computer scientists and then goes on to cover some of the core tasks in natural language processing (NLP), focussing on statistical tagging and parsing. We will look at how to evaluate taggers and parsers and see how well state-of-the-art tools perform given current techniques.

  • Machine Learning for Language Processing (L101) – Prof Ted Briscoe, Dr Stephen Clark – 16 h

    This module aims to provide an introduction to machine learning with specific application to tasks such as document classification, spam email filtering, language modelling, part-of-speech tagging, and named entity and event recognition for textual information extraction. We will cover supervised, weakly-supervised and unsupervised approaches using generative and discriminative classifiers based on graphical models, including (hidden) Markov models and CRFs, and clustering / dimensionality-reduction methods, such as latent Dirichlet allocation and neural word embeddings.

  • Modern Compiler Design (L25) – Prof Alan Mycroft, Dr David Chisnall – 16 h

    The LLVM project provides a modular set of libraries for building compilers, used in both academic research and industry. It therefore provides a rare opportunity for students to gain experience with a system that is both state-of-the-art in terms of research and also of direct industrial relevance. The course will focus largely one middle of the compiler – the analysis, transform, and optimisation pipeline – and will require the students to design and implement language-specific optimisations.

  • Multicore Semantics and Programming (R204) – Prof Peter Sewell, Dr Timothy Harris – 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.

  • Network Architectures (R02) – Prof Jon Crowcroft – 16 h

    The world needs more network architects! This module will discuss and critique historical and contemporary network architectures including ATM, TCP/IP and 3G, as well as cover emerging sensor networks and delay tolerant approaches.

  • Overview of Natural Language Processing (L90) – Dr Ekaterina Shutova, Dr Simone Teufel – 16 h

    This module introduces the fundamental techniques of natural language processing. It aims to explain the potential and the main limitations of these techniques. Some current research issues are introduced and some current and potential applications discussed and evaluated.

  • Principles of Data Science (L120) – Dr Richard Gibbens – 16 h

    This module will introduce students to the principles of Data Science that underpin key tools and techniques used both to describe and to gain insights into the properties of often large and complex datasets. The approach taken in the module will combine the development of mathematical theory with case studies taken from real-world application domains such as communications networks and road transport networks. The case studies will also highlight the use of modern software packages including R for both statistical computation as well as the graphical visualisation of statistical properties and results.

  • Research Skills Programme (RSP) – Prof Alan Blackwell, Prof Neil Dodgson, (and others) – 12 h

    To provide advice on and training in a variety of practical skills required for research. To provide training in a subset chosen from the diverse set of skills that will be useful in the other research-led modules, in the individual project, and in the student's future career.

The objective is for computer science researchers to develop facility in discussing and critiquing the aims of their research, especially for an audience drawn from other academic disciplines. Participants may include research students and academic guests from other University departments.

Lent term

  • A Mathematical Theory of Distributed Games and Strategies (M22) – Prof Glynn Winskel – 6 h

    This module will give a rapid introduction to ongoing research in developing a mathematical theory of distributed games in which a Player (or a team of players) can interact and compete against an Opponent (or a team of opponents) in a highly distributed fashion, without, for instance, enforcing that their moves occur in a sequential fashion, or need to alternate. Although phrased in terms of `Player' and `Opponent' the dichotomy Player vs. Opponent can stand for Process vs. Environment, Prover vs. Disprover, or Ally vs. Enemy. These alternatives indicate the wide range of potential applications in computer science, logic, and beyond.

  • Advanced Functional Programming (L28) – Dr Anil Madhavapeddy, Dr Jeremy Yallop, Prof Alan Mycroft, Dr Leo White, Dr KC Sivaramakrishnan – 16 h

    This module aims to cover at least four selected topics in enough detail and depth so that participants are potentially in a position to contribute to research on the topic. Each topic will be introduced with a lecture which, building on the material covered in the prerequisite courses, will make the current research literature accessible. The three seminar sessions will typically be run as a reading group with student presentations and discussion and will typically cover about six recent papers from the literature.

  • Biomedical Information Processing (R214) – Dr Anna Korhonen, Dr Pietro Lio' – 16 h

    Research done within biomedical sciences is generating vast amounts of information which can, when processed appropriately, improve our understanding of the complex processes that govern life, death and disease. This course surveys computational techniques that can be used to process biomedical data with the overall goal of supporting the processes of scientific inquiry, problem solving, and decision making in biomedical sciences. A variety of data types and sources will be introduced, along with data and text mining techniques that can be used to analyse, extract, discover and integrate biomedical information at levels ranging from molecular through human populations. The course surveys specific problems in biology, clinical medicine and public health and shows how information processing can support practical applications in these areas.

  • Computer Security: Current Applications and Research (R210) – Prof Ross Anderson, Dr Robert Watson, Daniel Thomas – 16 h

    In the second security course in the ACS, we turn our attention to active research topics in computer security at the Computer Laboratory. One unifying theme is how to build secure systems at scale that contain more secure and less secure components. Building on the lessons from multilevel secure systems and security protocols discussed in the first course, we will explore infrastructure versus applications; services versus clients; the use of smartcards and other cryptographic processors; API security; and failure modes from covert channels to concurrency vulnerabilities.

  • Discourse Processing (R216) – Dr Simone Teufel – 16 h

    This module provides an introduction to NLP research centered around discourse processing (i.e., the means by which larger pieces of text are structured), and to text summarisation methods, particularly those based on discourse processing.

    NEW: This module aims to introduce students to basic principles and methods of machine learning algorithms that are typically used for mining large data sets. In particular, we will look into algorithms typically used for analysing networks, fundamental principles of techniques such as decision trees and support vector machines, and finally, neural network architectures. The students will gain practical understanding through a coding exercise where they will implement and apply one machine learning algorithm on a particular large data set.

  • Research Skills Programme (RSP)(continuing) – 12 h

    To provide advice on and training in a variety of practical skills required for research. To provide training in a subset chosen from the diverse set of skills that will be useful in the other research-led modules, in the individual project, and in the student's future career. This programme must be taken by all M.Phil students and CPGS students.

  • System on Chip Design and Modelling (P35) – Dr David Greaves – 16 h

    A current-day system on a chip (SoC) consists of several different microprocessor subsystems together with memories and I/O interfaces. This practical module covers SoC design and modelling techniques with emphasis on architectural exploration, assertion-driven design and the concurrent development of hardware and embedded software.

  • Usability of Programming Languages (P201) – Prof Alan Blackwell – 16 h

    Compiler construction is one of the basic skills of all computer scientists, and thousands of new programming, scripting and customisation languages are created every year. Yet very few of these succeed in the market, or are well regarded by their users. This course addresses the research questions underlying the success of new programmable tools. A programming language is essentially a means of communicating between humans and computers. Traditional computer science research has studied the machine end of the communications link at great length, but there is a shortage of knowledge and research methods for understanding the human end of the link. This course provides practical research skills necessary to make advances in this essential field. The skills acquired will also be valuable for students intending to pursue research in advanced HCI, or designing evaluation studies as a part of their MPhil research project.

Easter term
