Deep learning has attracted tremendous attention from researchers in various fields of information engineering such as AI, computer vision, and language processing [Kalchbrenner and Blunsom, 2013; Krizhevsky et al., 2012; Mnih et al., 2013], but also from more traditional sciences such as physics, biology, and manufacturing [Anjos et al., 2015; Baldi et(More)
Standard sparse pseudo-input approximations to the Gaussian process (GP) cannot handle complex functions well. Sparse spectrum alternatives attempt to answer this but are known to over-fit. We suggest the use of variational inference for the sparse spectrum approximation to avoid both issues. We model the covariance function with a finite Fourier series(More)
Agile development methods are gaining adherents in a wide variety of industries. Agile proponents and those who support traditional process improvement have been equally vocal in their disdain for each other. However, it is unclear whether or not agile methods constitute an improvable „process.“ This paper discusses the relationship between agile methods(More)
Managing the evolution of independent or loosely coupled systems of systems (SoS) is difficult. Much of the difficulty resides in the ways that elements are combined to make up the SoS and how those elements interface. The Systems Engineering Research Center has been studying how new governance mechanisms drawn from agile, lean and other adaptive approaches(More)
INTRODUCTION There are very little clinical and pathological data on colorectal cancer among Indigenous people in Australia. METHODS A retrospective study on Indigenous patients treated for colorectal cancer at the Townsville and Cairns Base Hospitals from 1999 to 2004 was carried out in order to better characterise this disease in the Indigenous(More)
Delivering the most value for money when developing capabilities for a large system of systems is a complex issue. Several key factors affect the value of every particular piece of work, and those factors can change over time as the actual work effort evolves, the requirements change, and the value of desired capabilities independently rise and fall. Most(More)
The evolution of systems integration has reduced proprietary interfaces significantly. Aging federated systems contain proprietary interfaces which minimize upgrade flexibility. As product lines evolve their value increase can be attributed to the progress from interface standards to open systems architecture. Systems integration evolution for aircraft(More)
