Random forests

by Leo Breiman, E. Schapire - Machine Learning , 2001
"... Abstract. Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution for all trees in the forest. The generalization error for forests converges a.s. to a limit as the number of trees in the fo ..."

Internal estimates monitor error, strength, and correlation and these are used to show the response to increasing the number of features used in the splitting

Computational Models of Sensorimotor Integration

by Zoubin Ghahramani , Daniel M. Wolpert, Michael I. Jordan - SCIENCE , 1997
"... The sensorimotor integration system can be viewed as an observer attempting to estimate its own state and the state of the environment by integrating multiple sources of information. We describe a computational framework capturing this notion, and some specific models of integration and adaptati ..."

information from visual and auditory systems is integrated so as to reduce the variance in localization. (2) The effects of a remapping in the relation between visual and auditory space can be predicted from a simple learning rule. (3) The temporal propagation of errors in estimating the hand

Tractable inference for complex stochastic processes

by Xavier Boyen - In Proc. UAI , 1998
"... The monitoring and control of any dynamic system depends crucially on the ability to reason about its current status and its future trajectory. In the case of a stochastic system, these tasks typically involve the use of a belief state—a probability distribution over the state of the process at a gi ..."

Razor: A low-power pipeline based on circuit-level timing speculation

by Dan Ernst, Nam Sung Kim, Shidhartha Das, Sanjay Pant, Rajeev Rao, Toan Pham, Conrad Ziesler, David Blaauw, Todd Austin, Krisztian Flautner, Trevor Mudge - in Proc. IEEE/ACM Int. Symp. Microarchitect , 2003
"... With increasing clock frequencies and silicon integration, power aware computing has become a critical concern in the design of embedded processors and systems-on-chip. One of the more effective and widely used methods for poweraware computing is dynamic voltage scaling (DVS). In order to obtain the ..."

Automated Consistency Checking of Requirements Specifications

by Constance L. Heitmeyer, Ralph D. Jeffords, Bruce G. Labaw , 1996
"... This paper describes a formal analysis technique, called consistency checking, for automatic detection of errors, such as type errors, nondeterminism, missing cases, and circular definitions, in requirements specifications. The technique is designed to analyze requirements specifications expressed i ..."

Leading indicators of currency crises

by Graciela Kaminsky, Saul Lizondo, Carmen M. Reinhart - IMF Staff Papers , 1998
"... This paper examines the empirical evidence on currency crises and proposes a specific early warning system. This system involves monitoring the evolution of several indicators that tend to exhibit an unusual behavior in the periods preceding a crisis. When an indicator exceeds a certain threshold va ..."

Development and testing of the OPLS all-atom force field on conformational energetics and properties of organic liquids

by William L. Jorgensen, David S. Maxwell, Julian Tirado-rives - J. Am. Chem. Soc , 1996
"... ReceiVed June 27, 1996. ReVised Manuscript ReceiVed September 5, 1996X Abstract: The parametrization and testing of the OPLS all-atom force field for organic molecules and peptides are described. Parameters for both torsional and nonbonded energetics have been derived, while the bond stretching and ..."

and densities. The Monte Carlo simulations included sampling all internal and intermolecular degrees of freedom. It is found that such non-polar and monofunctional systems do not show significant condensed-phase effects on internal energies in going from the gas phase to the pure liquids.

Measurement and Correction of Systematic Odometry Errors in Mobile Robots

by Johann Borenstein, Liqiang Feng, Corresponding Johann Borenstein - IEEE Transactions on Robotics and Automation , 1996
"... Odometry is the most widely used method for determining the momentary position of a mobile robot. In most practical applications odometry provides easily accessible real-time positioning information in-between periodic absolute position measurements. The frequency at which the (usually costly and/or ..."
