In this lecture I will present network-theoretic tools [1-5] to filter information in large-scale datasets and I will show that these are powerful tools to study complex datasets. In particular I will introduce correlation-based information filtering networks and the planar filtered graphs (PMFG) and I will show that applications to financial data-sets can meaningfully identify industrial activities and structural market changes [2-5]. It has been shown that by making use of the 3-clique structure of the PMFG a clustering can be extracted allowing dimensionality reduction that keeps both local information and global hierarchy in a deterministic manner without the use of any prior information [6,4]. However, the algorithm so far proposed to construct the PMFG is numerically costly with O(N3) computational complexity and cannot be applied to large-scale data. There is therefore scope to search for novel algorithms that can provide, in a numerically efficient way, such a reduction to planar filtered graphs. I will introduce a new algorithm, the TMFG (Triangulated Maximally Filtered Graph), that efficiently extracts a planar subgraph which optimizes an objective function. The method is scalable to very large datasets and it can take advantage of parallel and GPUs computing. The method is adaptable allowing online updating and learning with continuous insertion and deletion of new data as well changes in the strength of the similarity measure .
Finally I will also show that filtered graphs are valuable tools for risk management and portfolio optimization too [8-9] and they allow to construct probabilistic sparse modeling for financial systems that can be used for forecasting, stress testing and risk allocation .

Douglas B. Kothe (Doug) has over three decades of experience in conducting and leading applied R&D in computational applications designed to simulate complex physical phenomena in the energy, defense, and manufacturing sectors. Doug is currently the Director of the Exascale Computing Project (ECP). Prior to that, he was Deputy Associate Laboratory Director of the Computing and Computational Sciences Directorate (CCSD) at Oak Ridge National Laboratory (ORNL). Other prior positions for Doug at ORNL, where he has been since 2006, include Director of the Consortium for Advanced Simulation of Light Water Reactors, DOE’s first Energy Innovation Hub (2010-2015), and Director of Science at the National Center for Computational Sciences (2006-2010).
Before coming to ORNL, Doug spent 20 years at Los Alamos National Laboratory, where he held a number of technical and line and program management positions, with a common theme being the development and application of modeling and simulation technologies targeting multi-physics phenomena characterized in part by the presence of compressible or incompressible interfacial fluid flow. Doug also spent one year at Lawrence Livermore National Laboratory in the late 1980s as a physicist in defense sciences.
Doug holds a Bachelor in Science in Chemical Engineering from the University of Missouri – Columbia (1983) and a Masters in Science (1986) and Doctor of Philosophy (1987) in Nuclear Engineering from Purdue University.
The Exascale Computing Project (ECP), launched in 2016 by the US Department of Energy (DOE), is an aggressive research, development, and deployment project focused on delivery of mission critical applications, an integrated software stack, and exascale hardware technology advances. These products are being deployed to DOE high performance computing (HPC) facilities on pre-exascale and ultimately exascale computers, where they will address critical challenges in national security, energy assurance, economic competitiveness, healthcare, and scientific discovery. Illustrative examples will be given on how the ECP teams are delivering in its three areas of technical focus:
- Applications: Exascale-capable applications are a foundational element of the ECP and are the delivery vehicle for solutions and insights to key national challenges and emerging technical areas such as machine learning and artificial intelligence. Problems heretofore intractable are accessible with ECP applications.
- Software Technologies: Software technologies play an essential enabling role as the underlying technology to application integration and efficacy on computing systems. An expanded and vertically integrated software stack is being developed to include advanced mathematical libraries and frameworks, extreme-scale programming environments, tools, and visualization libraries.
- Hardware and Integration: ECP is focused on integration of applications, software, and hardware innovations to ensure a capable exascale computing ecosystem. Working closely with the DOE HPC facilities, the project supports US HPC vendor research and development of innovative architectures for competitive exascale system designs.
Imperial College London, UK
Dr. Moore was born in Toccoa, Georgia, and received his Bachelor of Mechanical Engineering in 1987, his Master of Science in Mechanical Engineering in 1988 and his Ph.D. in 1991, all from the Georgia Institute of Technology. He was the first PhD student of Dr. David N. Ku, MD PhD, and his thesis work was a collaborative project with vascular surgeon Dr. Christopher Zarins and vascular pathologist Dr. Seymour Glagov. He had postdoctoral training at the Swiss Institute of Technology at Lausanne, 1991 – 1994, where he also helped set up a new biomedical engineering lab. From 1994 – 2003 Dr. Moore served as a professor of Mechanical and Biomedical Engineering, Florida International University. He moved to Texas A&M University in 2003, where he served as the Carolyn S. and Tommie E. Lohman ’59 Professor of Biomedical Engineering and Director of Graduate Studies. In Jaunary 2013, he joined Imperial College as the Bagrit and Royal Academy of Engineering Chair in Medical Device Design, and Director of Research for the Department of Bioengineering.
Dr. Moore’s research interests include Cardiovascular Biomechanics, Stents, Implantable Devices, Atherosclerosis, and the Lymphatic System. His research focuses on the role of biomechanics in the formation and treatment of diseases such as atherosclerosis and cancer. His cardiovascular biomechanics research includes the first finite element models of artery walls to include residual stress, the first studies of the effects of combined flow and stretch on vascular endothelium, early work on the effects of myocardial contraction on coronary artery flow patterns, and the first studies of the effects of stents on both blood flow patterns and artery wall stress. This work resulted in the development of two novel stent designs aimed at optimizing post-implant biomechanics for the prevention of restenosis, as well as new testing devices for implants that employ more physiologic mechanical forces (currently marketed by Bose). His work on the effects of stretch gradients on cells was awarded best paper of the year in the Journal of Biomechanical Engineering for 2011. In collaboration with Dr. Kumbakonam Rajagopal, he developed constitutive models of strain-accelerated degradation of polymers used in medical implants. His research on lymphatic system biomechanics, initiated in 2004 with Dr. David Zawieja, has provided unprecedented insight into the pumping characteristics of the system and the transport of nitric oxide, antigens, and chemokines in lymphatic tissues. He is currently developing two technologies for preventing and resolving secondary lymphedema, which typically forms subsequent to cancer surgery. Along with his funding from government, charity, and industry sources, Dr. Moore has received multiple patents for medical devices and testing equipment. Dr. Moore has also co-founded two startup companies.
Lymphatic vessels play an important role in maintaining fluid balance by returning interstitial fluid and proteins to the blood. This system also plays a crucial role in transporting immune cells into lymph nodes where adaptive immunity is formed. Cancer cells exploit the lymphatic system to spread to other parts of the body. All of the deadliest forms of cancer spread via lymphatics, and often set up secondary tumours in other parts of the body such as the brain, lungs and bone marrow. Approximately 90% of all cancer deaths are due to these secondary tumours. However, knowledge of the human lymphatic system is severely limited by the lack of technologies to measure pressure, flow rate or diameter in any vessel. Interstitial fluid which has been transported out of the walls of small blood vessels is collected by highly porous and largely passive initial lymphatic vessels, which converge into collecting lymphatic vessels, featuring one-way valves and mural musculature. Lymphatic muscle cells actively contract to push fluid centrally. Computational modelling has played an important role in informing our understanding of lymphatic pumping, such as how the system generates the suction required to draw in fluid from interstitial tissue spaces, many of which exhibit subatmospheric pressures. Disruptions to lymphatic pumping often result in an incurable swelling referred to as lymphoedema. Improving our understanding of lymphatic function across multiple length and time scales will play a role in developing clinical interventions to prevent and cure these devastating disease processes.
