Network Comparison

Abstract
Networks are ubiquitous, a prime example being social network sites such as Facebook, and yet there is a lot which is not understood about them. Even for the seemingly simple question of how similar two networks are, to date there is no generally accepted method available to answer this question.
The proposed project will address exactly this issue, how to compare networks. Network comparison is of considerable importance for example when trying to compare protein-protein interaction networks of organisms under different form of stress, or when trying to compare protein-protein interaction networks of people carrying a certain disease to that of people without the disease.
The statistics will be applicable to any types of networks, and they could be used to track changes in networks over time.
While constructing such a statistic for network comparison may be relatively straightforward, for statistical tests its probabilistic properties have to be understood. Achieving such understanding requires considerable expertise in probability, as there are a number of questions which have to be tackled in order to establish a useful asymptotic result.
Similarly, the statistical properties of the new statistics have to be understood. How well do they separate models which are generated from just slightly different models? How can suitable test procedures be implemented?
Preliminary studies have shown that our method can be used to reconstruct phylogenetic trees based on protein-protein interaction networks. If confirmed, then this is the first result which shows that the topology of protein-protein interaction networks alone contains information about evolution. This result is of considerable interest in biology, and its biological implications have to be studied in detail.
Experience has seen that networks are able to capture the imagination, and are a suitable topic for outreach activities. Hence we intend to develop some lectures aimed at a general audience, to be offered to schools, via departmental contacts in the first instance, as well as at public science forums.
There will be a blog about our research on the Oxford Sparks portal, an on-line public science website.

Planned Impact
The most striking impact of the research could be on our view of evolution; protein-protein interaction networks contain information about evolution in their topology.
The research will be of immediate interests to companies like e-Therapeutics who specialise in network pharmacology. There is an existing collaboration between Gesine Reinert and Alan Whitmore from e-Therapeutics on Parkinson's disease. The method would allow comparing different networks which are conjectured to represent the disease, and would help identify drug targets. Charlotte Deane collaborates with Matt Page and Colin Stubberfiled at UCB - the biopharma company on how networks change over time and between different disease and healthy states.
The potential applications are wide-ranging. One could compare the communication networks of different NHS trusts to assess whether there is a correlation between efficiency and network topology. Gesine Reinert has discussed related questions with Dr Kazem Rahimi at the George Centre for Healthcare Innovation.
Network comparison could shed light on trade behaviour through the comparison of trade networks across geographical regions and commodities. These results could in turn inform international development policies.
The research would advance the scientific areas of applied probability, statistics, biology, social science, computer science and the emerging field of network science, through a new method, new approaches, and new results in specific applications.
The project would train two postdoctoral researchers as well as project students. The results would be disseminated to the wider public via lectures and a blog, and they may motivate young people to take up studies in mathematics and statistics.
Finally, our results may help establish the emerging discipline of Network Science as a discipline with its own research questions and tools, which go beyond the research questions raised in particular applications.

Description | We have developed two tools to compare networks, with the aim to find local patterns in networks; they are called Netdis and NetEMD. We have also extended network tools to include the case where nodes in networks have certain characteristics, such as damage caused when the node is hit by a disaster. We have also developed a subsampling algorithm for Netdis which allows comparing networks even when the networks are not fully known. This algorithm can be used to compare large networks such as websites linking to other websites; the exact number of websites does not have to be known in order to carry out the comparison. The algorithm is of interest to other fields as it is based on bootstrap on networks. We not only give the algorithm but we also prove that it converges to the correct outcome as long as the graph is sufficiently homogeneous, while allowing for some heterogeneity. Our second method, NetEMD (the paper is currently under revision), compares networks directly through the distribution of features of the networks, such as subgraph counts. The use of features also appears in classification of networks through machine learning kernels. NetEMD performs as well as the best-performing machine learning kernel methods we tried, without requiring any additional information beyond the network topology. To understand what to expect when comparing networks, we carried out some thorough mathematical analysis of underlying models. In insurance networks which relate catastrophic risks we determined two key indices which describe the behaviour of the system depending on the underlying networks. These indices can be used to monitor markets and also to regulate markets. We are still in the process to find out why our methods work so well on biological data - do they capture some evolutionary principle? It turns out that our network comparison methods give slightly different results on newer networks. We explored this difference by separating the protein-protein interaction data according to the experimental method used to obtain the data. For one method (TAP-MS) the network comparison methods do not work very well, whereas they perform well on the other main method (Yeast-two-hybrid). There are good underlying reasons for this difference, the two methods produce different types of errors and are biased towards different types of proteins. Based on these insights we have started building an evolutionary model for protein-protein interaction networks. |
Exploitation Route | Our method was used to compare ecological networks, by Drew Purves and his group when he was at Microsoft Research, Cambridge. Sarika Jalan and her group use it to analyse networks arising from fMRI data. We understand that GCHQ has been using our methods. Our methods form the basis of a 2-year project with Accenture on threat detection in networks. The network comparison methods are almost fast enough to give real time network comparisons; we are trying to make them faster so that they can be used for detecting anomalies in networks, with possible application in cyber security. The methods will be developed to yield fine-grained information about locations of changes; which node combinations are the ones which trigger the network comparison statistic to be larger than expected? The theoretical underpinning will rely on a framework for comparing multivariate discrete distributions. The project has served as inspiration for an EPSRC Fellowship proposal. |

Description | Our network comparison methods use counts of small subgraphs in a network as features which can be used to classify networks and to test whether networks come from a particular distribution. These count statistics are local summaries and hence can be updated efficiently. Moreover a detailed analysis of the network comparison statistic reveals the main local differences between networks through their contribution in the network statistic. This work lies at the foundation of a 2-year project with Accenture on threat detection in networks, with particular emphasis on anti-money laundering and modern slavery. This local refinement is also of interest both for our collaborators in network pharmacology and in cyber security, as follows. Suitable network comparison methods are key to identify subnetworks of protein-protein interaction networks which are relevant to a certain disease. In order to achieve more impact a fine scale analysis is now required so that particular protein combinations can be identified which distinguish healthy state from disease state. Through the funded project our collaboration with e-Therapeutics has intensified and now we are carrying out a detailed network analysis using scores on interactions, to detect small parts in a network which may change in the disease state. We anticipate a sandpit meeting with e-Therapeutics and interested researchers to take place before April 2018, funded through the COSTNET grant. Gesine Reinert has also been collaborating with Prof Niall Adams (Imperial) to test our network comparison methods, combined with his change point methods, on GCHQ data sets. We expect to submit a grant proposal in the near future to explore this method further. Our theoretical results have attracted interest from insurance companies and regulators; indeed we were awarded a Science of Risk Prize by Lloyd's of London. The Science of Risk Prize has increased the visibility of our work, and we have had conversations with representatives of the Bank of England about regulatory interventions to control systemic risk in insurance networks. Network comparison also plays a role in a follow-up project, funded by Novo Nordisk, on identifying modules in liver protein interaction network data under different conditions. The project provided material for 3 M.Sc. projects, 3 4th-year projects, one summer student project, and one visiting student project. So far 5 publications arose from these projects, with one more paper submitted. Perhaps the most important impact is the impact through our outreach activities. Networks are a good subject to explain to A-level pupils, and we have enjoyed talking to them. Our talk on networks is now part of the departmental repertoire for open days. It is also useful to have the blogpost on our research; we point to it regularly. |

Impact | Gesine Reinert was invited to two scoping meetings for the Alan Turing Institute. At these meetings she talked about network analysis and its applicability for high-dimensional data sets. There were about 30 scoping meetings, and only 5 themes were eventually selected as focus points for the Alan Turing Institute. Network analysis is one of them. Subsequently Gesine Reinert was elected as an Alan Turing Faculty Fellow and is regularly called upon to discuss network issues, both as training of early career researchers and in a consulting role for companies such as Accenture. |
