COMPGC26 - Artificial Intelligence and Neural Computing
This database contains the 2017-18 versions of syllabuses.
Note: Whilst every effort is made to keep the syllabus and assessment records correct, the precise details must be checked with the lecturer(s).
|Code||COMPGC26 (Also taught as COMP3058)|
|Prerequisites||Students should have either: (1) a degree in Mathematics; or (2) a degree in Philosophy in which they have completed and passed a formal logic module.|
|Taught By||Denise Gorse (50%)|
Anthony Hunter (50%)
|Aims||This course introduces artificial intelligence and neural computing as both technical subjects and as fields of intellectual activity. The overall targets are: (1) to present basic methods of expressing knowledge in forms suitable for holding in computing systems, together with methods for deriving consequences from that knowledge by automated reasoning; (2) to present basic methods for learning knowledge; and (3) to introduce neural computing as an alternative knowledge acquisition/representation paradigm, to explain its basic principles and their relationship to neurobiological models, to describe a range of neural computing techniques and their application areas.|
|Learning Outcomes||Ability to identify problems that can be expressed in terms of search problems or logic problems, and translate them into the appropriate form, and know how they could be addressed using an algorithmic approach. Ability to identify problems that can be expressed in terms of neural networks, and to select an appropriate learning methodology for the problem area.|
