Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the specified learning outcomes by teaching the module syllabus in lectures, and supporting the assimilation and understanding of the taught material via tutorial classes. The practical design and technical skills related to the subject are acquired through coursework involving an assignment on pattern recognition system design; the performance of the designed pattern recognition system is characterised via laboratory experiments.
Learning and teaching methods include:
Lectures: 10 weeks, 3 hours per week
Tutorials: 6-8 weeks, 1 hour per week
Labs: Pattern Recognition Experiment – set and marked by JK, starting in Week 6, due Week 9, Preparation via assignment
Assignment(s): Pattern recognition system design (linked to Pattern Recognition Lab) issued in Week 3, due Week 6.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of the terminology, concepts and theory of statistical and adaptive signal processing, as well as the ability to analyse problems and apply mathematical models of signal processing to solve and predict effects. The Assignment will assess the ability to design pattern recognition systems. The laboratory experiment will evaluate the acquired technical skills and expertise required for performance characterisation of pattern recognition systems.
Thus, the summative assessment for this module consists of the following.
· 2-hour, closed-book written examination
· Pattern recognition system design: An assignment involving the design of a pattern classification system (5-10 pages), due Tuesday Week 6 (assignment deadline should be checked in the Assignment Calendar)
· Pattern Recognition Experiment A laboratory experiment concerned with pattern recognition system evaluation (circa 10 pages) due Tuesday Week 9 (assignment deadline should be checked in the Assignment Calendar)
Formative assessment and feedback
The main mechanism for formative assessment will be a set of five tutorial problem sheets which the students will be expected to solve prior to the timetabled tutorial classes. The tutorial classes will provide the main forum for formative feedback. In addition, formative assessment and feedback may occur:
· During lectures, by question and answer sessions
· During tutorials/tutorial classes
· During supervised laboratory sessions
· During meetings with lecturers and tutor.
