Very simple classification rules perform well on most commonly used datasets
- Machine Learning
, 1993
"... The classification rules induced by machine learning systems are judged by two criteria: their classification accuracy on an independent test set (henceforth "accuracy"), and their complexity. The relationship between these two criteria is, of course, of keen interest to the machin ..."

to the machine learning community. There are in the literature some indications that very simple rules may achieve surprisingly high accuracy on many datasets. For example, Rendell occasionally remarks that many real world datasets have "few peaks (often just one) " and so are &
Powernap: Eliminating server idle power
- In International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS
, 2009
"... Data center power consumption is growing to unprece-dented levels: the EPA estimates U.S. data centers will con-sume 100 billion kilowatt hours annually by 2011. Much of this energy is wasted in idle systems: in typical deployments, server utilization is below 30%, but idle servers still con-sume 60 ..."

In this paper, we propose PowerNap, an energy-conservation approach where the entire system transitions rapidly be-tween a high-performance active state and a
I. THE PEAK DEMAND PROBLEM
"... A grid connected photovoltaic system aimed at peak demand reduction in areas with hot weather is presented. It uses the "Perturbe and observe " technique to track the maximum power point of the cell array, and provides a high quality current waveform. The islanding of the system is avoided ..."

Adaptive Run-time Performance Optimization Through Scalable Client Request Rate Control
"... Today’s Internet-scale computing systems often run at a low average load with only occasional peak performance demands. Consequently, computing resources are often overdimensioned, leading to high costs. While load control techniques between clients and servers can help to better utilize a given sys ..."

A critical role for the right fronto-insular cortex in switching between central-executive and default-mode networks.
- Proc Natl Acad Sci USA
, 2008
"... Cognitively demanding tasks that evoke activation in the brain's central-executive network (CEN) have been consistently shown to evoke decreased activation (deactivation) in the default-mode network (DMN). The neural mechanisms underlying this switch between activation and deactivation of larg ..."

Density Forecasting for Long-Term Peak Electricity Demand
- IEEE TRANSACTIONS ON POWER SYSTEMS
, 2009
"... Long-term electricity demand forecasting plays an important role in planning for future generation facilities and transmission augmentation. In a long-term context, planners must adopt a probabilistic view of potential peak demand levels. Therefore density forecasts (providing estimates of the full ..."

The proposed methodology has been used to forecast the probability distribution of annual and weekly peak electricity demand for South Australia since 2007. The performance of the methodology is evaluated by comparing the forecast
Whom You Know Matters: Venture Capital Networks and Investment Performance,
- Journal of Finance

We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company inv ..."

A Bandwidth-Efficient Architecture for Media Processing
- In 31st International Symposium on Microarchitecture
, 1998
"... Media applications are characterized by large amounts of available parallelism, little data reuse, and a high computation to memory access ratio. While these characteristics are poorly matched to conventional microprocessor architectures, they are a good fit for modern VLSI technology with its high ..."

Exploring Power-Voltage Relationship for Distributed Peak Demand Flattening in Microgrids

Thus, researchers propose di↵erent techniques to flatten peak de-mand in individual residential buildings. However, if each home in the grid flattens peak demand only with its own power cons ..."
