Postgraduate Course: Methods for the Analysis of Networks (INFR11083)
|School||School of Informatics
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Available to all students
|Summary||This course studies methods for analysing the emergent properties of naturally-occurring networks. The past decade has brought overabundant quantitative information on various complex distributed systems, which one can often embed into a network presentation. Examples include: social networks, food webs, the world wide web, (natural) neural networks, metabolic and signalling networks. There is now a growing corpus of network-based methods and algorithms that can help build a bigger picture and approach questions about the design and global properties of such systems. One can in particular ask questions such as: how resilient is a network, how well does it propagate information (or diseases), how modular is it, what is a likely growth scenario, etc. These methods are sometimes given the catch phrase "network science" to stress their relative independence from the particulars of the network of interest --- which in itself is a remarkable fact.
+ Various types of data and networks. - Typology of random graph models: Erdős-Rényi, scale-free, hierarchical. - Local properties: edge density, degree distribution, clustering coefficient, assortativity, motifs. - Global properties: path lengths, centrality, modularity/community. - Algorithms: clustering methods, power-law fitting, hierarchy reconstruction. - Examples of networks. One or more sample domain of application, taken from areas such as the following:
+ Protein networks: modular structures, propagation of copy number perturbations, phase transitions in structural protein networks.
+ Neural networks: spatial growth models, hierarchical structure, propagation of excitation, scaling across different species.
+ Social networks: propagation of innovation, citation, epidemics.

Course Delivery Information
|Not being delivered|
| 1 - Recognise situations where data can be represented as a graph (directed, weighted or not, as appropriate).
2 - Explain how to compute the usual local or global metrics on large graphs.
3 - Given a large graph, identify the classes of random graphs of which it is likely to be a member.
4 - Given an existing network, identify possible associated growth scenarios.
5 - Describe the dynamics one can endow upon a graph and their asymptotic properties.
