Query by Committee
, 1992
"... We propose an algorithm called query by committee, in which a committee of students is trained on the same data set. The next query is chosen according to the principle of maximal disagreement. The algorithm is studied for two toy models: the high-low game and perceptron learning of another perceptr ..."

gain approaches zero and the generalization error decreases with a relatively slow inverse power law. We suggest that asymptotically finite information gain may be an important characteristic of good query algorithms.
Hierarchical Modelling and Analysis for Spatial Data. Chapman and Hall/CRC,
, 2004
"... Abstract Often, there are two streams in statistical research -one developed by practitioners and other by main stream statisticians. Development of geostatistics is a very good example where pioneering work under realistic assumptions came from mining engineers whereas it is only now that statisti ..."

in There is no doubt that the availability of cheap and powerful computers has increased the interest in ML applications. With spatially correlated data, the maximization of the likelihood requires considerable computer power mainly for two numerical operations: matrix inversion and maximization in multidimensional

Social Potential Fields: A Distributed Behavioral Control for Autonomous Robots
, 1999
"... A Very Large Scale Robotic (VLSR) system may consist of from hundreds to perhaps tens of thousands or more autonomous robots. The costs of robots are going down, and the robots are getting more compact, more capable, and more flexible. Hence, in the near future, we expect to see many industrial and ..."

groups. The force laws are inverse-power force laws, incorporating both attraction and repulsion. The force laws can be distinct and to some degree they reflect the 'social relations' among robots. Therefore we call our method social potential fields. An individual robot's motion
Inverse cubic law for the distribution of stock price variations
- European Physical Journal B
, 1998
"... The probability distribution of stock price changes is studied by analyzing a database (the Trades and Quotes Database) documenting every trade for all stocks in three major US stock markets, for the two year period Jan 1994 – Dec 1995. A sample of 40 million data points is extracted, which is subst ..."

PACS numbers: 89.90.+n Typeset using REVTEX 1 The asymptotic behavior of the increment distribution of economic indices has
Mitigating amdahl’s law through epi throttling
- In Proceedings of International Symposium on Computer Architecture
, 2005
"... This paper is motivated by three recent trends in computer design. First, chip multi-processors (CMPs) with increasing numbers of CPU cores per chip are becoming common. Second, multi-threaded software that can take advantage of CMPs will soon become prevalent. Due to the nature of the algorithms, t ..."

, these multi-threaded programs inherently will have phases of sequential execution; Amdahl’s law dictates that the speedup of such parallel programs will be limited by the sequential portion of the computation. Finally, increasing levels of on-chip integration coupled with a slowing rate of reduction in supply
Random texts exhibit Zipf's-law-like word frequency distribution
- IEEE Transactions on Information Theory
, 1992
"... are scanned from a copy of the paper (apologize for the poor quality). It is shown that the distribution of word frequencies for randomly generated texts is very similar to Zipf’s law observed in natural languages such as the English. The facts that the frequency of occurrence of a word is almost an ..."

an inverse power law function of its rank and the exponent of this inverse power law is very close to 1 are largely due to the transformation from the word’s length to its rank, which stretches an exponential function to a power law function. key words: statistical linguistics, Zipf’s law, power-law
Leakage Current: Moore's Law Meets Static Power

"... for some time. Figure 1 shows total chip dynamic and static power consumption trends based on 2002 statistics normalized to the 2001 International Technology Roadmap for Semiconductors. The ITRS projects a decrease in dynamic power per device over time. However, if we assume a doubling of o ..."
