COMP112 Web Development and Digital Media S1

For those attracted by the creative possibilities of web development, COMP112 will provide the knowledge and practical skills to make design concepts a reality. While COMP112 expects that students have used a computer before, it is not an advanced course, and is suitable for students not majoring in Computer Science. Computer Science majors will also find COMP112 beneficial; it provides a solid grounding in web development, and provides the foundation for our advanced web development course, COSC212.

COMP150 Practical Programming S1

An introduction to the basics of programming using the Python programming language, with an emphasis on practical topics. Suitable both for students who do not intend to major in Computer Science, and as preparation for COMP160.

COMP160 General Programming S2, SS

This paper teaches the basics of computer programming, using as an example the Java programming language. You will learn about algorithms, object oriented design, the basics of the Java language and libraries, and will receive an introduction to graphical user interfaces and programming for the web. This will also provide a base from which you can learn other programming languages and techniques. COMP160 will also develop problem solving skills. It is aprerequisite to all second year papers in Computer Science. COMP160 does not assume any particular background except for basic computer literacy, but students who wish to be well prepared might consider taking COMP150 first.

It is a useful paper both for those interested only in building websites and for those with a more general interest in Computer Science.

COSC241 Programming and Problem Solving S1

This paper builds on and extends the knowledge students have gained of programming and the Java language in COMP160. More advanced programming ideas, such as recursion and abstract data type design, are introduced, as well as their implementations in Java. Then a variety of different data structures are discussed together with the algorithms to query and modify them. Theoretical and practical analyses of efficiency are used at each stage of the paper.

COSC242 Algorithms and Data Structures S2

This paper extends the variety of data types familiar from COMP160 and COSC241, and looks more closely at the algorithms that operate on them. Among the new data types to be treated are balanced search trees and graphs. The performance of algorithms is a unifying theme throughout, and so the paper provides an introduction to the analysis of algorithms and their classification according to complexity. Students taking this paper will be introduced to their second programming language — all practical work will be done in C. Prior or concurrent enrolment in any MATH paper is recommended.

COSC326 Effective Programming S1, S2, SS

This paper aims to improve and develop programming skills by setting a series of exercises which require an analytical and creative approach to problem solving. Most, but not all, of these exercises will involve programming tasks. Some will not use computers at all, some will use them only for ancillary tasks. Each solution will be assessed against the requirements and students will be expected to go back and rework each problem until it is completed satisfactorily. Students will be required to fully test and debug their programs as well as learn to identify inefficiencies. The main objectives of this course are to develop and foster general skills relating to computer related techniques, understanding a problem, problem solving strategies and working with people. Most of the exercises will require working in pairs or in teams, although some exercises are individual.

The second phase covers current research within the field, and will be in a more open, student driven format. The material will be different every year, as it will be driven by your specific interests. Topics which have been frequently covered in the past include: advanced neural network theory, applications to vision and robotics, purpose built hardware ("neurocomputers"), applications within artificial life and software agents, neural/symbolic hybrids, mathem

COSC421 Neural Models of Language NA

This paper addresses the question of how language is implemented in the human brain. Answering this question draws on research in several disciplines: neuroscience, psychology, linguistics and computational modelling. The aim of the course is to provide an accessible introduction to the relevant topics for students from each of these disciplines. We will approach the topic by focussing on the interface between language and the sensorimotor system. We consider an observer perceiving a simple concrete event (a man grabbing a cup), and examine what is involved in converting the sensorimotor representation of this event to a linguistic representation - for instance, the English sentence 'The man grabbed a cup'.

There are three parts to the course.

  • Part 1: Models of the perception, execution and representation of reach-to-grasp actions. (Visual attention, object classification, visuomotor control, action recognition, working memory representations.)
  • Part 2: Models of natural language syntax. (Chomsky's Minimalism, construction grammar, statistical language models.)
  • Part 3: Models of language acquisition in infants. (Phonological, lexical and syntactic development.)

Students will learn about the key empirical methods employed in psychology and neuroscience (behavioural experiments, neuroimaging, single-cell recording, lesion studies), some of the influential computational models of sensorimotor cognition and language processing (saliency maps, convolutional networks, motor control, the mirror system, competitive queueing networks, Elman networks, cross-situational word learning) and the basics of two influential syntactic theories (Chomsky's Minimalism and Goldberg's Construction Grammar).

COSC441 Concurrent Programming NA

This paper presents theory and practice of concurrent programming, including locks, transactional memory, and message passing; multicore and distributed systems; and specification and testing of protocols. Concurrent programming is about building programs in which many activities are taking place, and the existence of and collaboration between these activities is essential to the program's design. In distributed systems, like credit card systems and telephone networks, the activities happen on physically separate machines communicating by sending messages over wires or radio channels. In multicore computers, the activities may take place on one or many cores and they may communicate through shared memory. The difficulties and principles are similar.

The first half of the paper is about shared memory concurrency, presenting general concepts in the context of POSIX threads. The second half is about message passing between logicallyseparate processes, using Erlang. There will also be material on specification and verification. Students will learn about designing, implementing, and testing concurrent and distributed programs. Students will learn about deadlock, starvation, livelock, races, and such hazards, about why "let it crash" is a good approach to errors, about the difference between task parallelism and data parallelism, and some concurrency design patterns.
