Performance metrics for energy spectrum estimation

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
Nuclear spectroscopy frequently involves estimating the distribution of photon energies (energy spectrum). The evaluation of spectral estimates within the literature are often subjective. Efforts to quantify the quality of the estimation generally utilize a measure based on the integrated square of error.

A Psychovisual Quality Metric in Free-Energy Principle

IEEE Transactions on Image Processing, 2012
In this paper, we propose a new psychovisual quality metric of images based on recent developments in brain theory and neuroscience, particularly the free-energy principle. The perception and understanding of an image is modeled as an active inference process, in which the brain tries to explain the scene using an internal generative model.

Roadmapping ICT: An Absolute Energy Efficiency Metric

Journal of Optical Communications and Networking, 2011
We describe an absolute energy efficiency metric (measured in dBe) that can be universally applied to any ICT system, subsystem and component. It shows what energy efficiency improvements are possible for any data processing/transmission/storage system.

Energy-Based Metric for Ensemble Selection

2012
Ensemble selection copes with the reduction of an ensemble of the predictive models to reduce its response time and increase its accuracy. A number of selection methods via greedy search of the space of all possible ensemble subsets have been recently proposed.

ON THE CALABI ENERGY OF EXTREMAL KÄHLER METRICS

International Journal of Mathematics, 1995
Fix a positive (1, 1)-class on a compact Kählerian manifold. Given a Kähler form representing this class, define its Calabi energy to be the L2-norm of its scalar curvature. This note proves that a critical metric for the Calabi energy, if any, is a global minimum among representatives of the chosen class, and that the critical value is determined a ...

Energy Multipliers for Perturbations of the Schwarzschild Metric

Communications in Mathematical Physics, 2009
Consider a space-time homeomorphic to \({\mathbb R}^2\times S^2\), and let \((t,r,\theta,\phi)\) be the standard coordinates there; \(t\) is the time variable, \(r\) is the radial coordinate, \(\theta\) and \(\phi\) are longitude and colatitude coordinates, respectively.

Energy Metrics: On Various Valuation Properties of Energy

1994
Economic methods for evaluating environmental change have been identified, presented and discussed in the early chapters of this book. It would now be appropriate to round up these views with an addendum on energy-based valuation methods.

Energy Resources Use Metrics

2016
Energy resources use has been considered as a key component of sustainable development. Data related to global, regional, state, sector, industry and process demonstrate that a significant reduction of energy resources for a given production rate in manufacturing processes requires an introduction of transformational technologies at the process level ...
