Images and videos are subject to a wide variety of distortions during acquisition, digitizing, processing, restoration, compression, storage, transmission and reproduction, any of which may result in degradation in visual quality. That is why image quality assessment plays a major role in many image processing applications. Image and video quality metrics can be classified by using a number of ...

When evaluating architectural and packaging options for an architecture, one commonly encounters the problem of meeting performance requirements within the constraints of weight, volume and power envelope as well as the amount of computation performance that can be realized with a given physical envelope. This assessment process can be guided by a metric that we have found to be relatively cons...

There are numerous parameters that influence the availability of long range aircraft. In order to develop models evaluating aircraft availability, an understanding of these parameters, along with the corresponding metrics, is required. An analysis of historical data for a modern long range transport aircraft shows that unscheduled organizational-level maintenance and depot maintenance are the l...

In spite of the widespread adoption of virtualization and consolidation, there exists no consensus with respect to how to benchmark consolidated servers that run multiple guest VMs on the same physical hardware. For example, VMware proposes VMmark which basically computes the geometric mean of normalized throughput values across the VMs; Intel uses vConsolidate which reports a weighted arithmet...

Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to eval...

The paper proposes a Constrained EntityAlignment F-Measure (CEAF) for evaluating coreference resolution. The metric is computed by aligning reference and system entities (or coreference chains) with the constraint that a system (reference) entity is aligned with at most one reference (system) entity. We show that the best alignment is a maximum bipartite matching problem which can be solved by ...

Research into intelligent systems and intelligent control is burgeoning. However, there is no consensus on how to define or measure an intelligent system. This lack of rigor hinders the ability to measure progress in the field and to compare different systems’ capabilities. We discuss some of the challenges and issues in defining performance metrics for intelligent systems and issue a call to a...
