predictive model for estimating the value of future cases). At the core of the process is the application of specific data-mining methods for pattern discovery and extraction. 1 This article begins by discussing the historical context of KDD and data mining and their intersection with other related fields.

Measuring the information content of stock trades

by Joel Hasbrouck - Journal of Finance , 1991
"... This paper suggests that the interactions of security trades and quote revisions be modeled as a vector autoregressive system. Within this framework, a trade's information effect may be meaningfully measured as the ultimate price impact of the trade innovation. Estimates for a sample of NYSE is ..."

Capacity Limits of MIMO Channels

by Andrea Goldsmith, Sriram Vishwanath, et al. - IEEE J. SELECT. AREAS COMMUN , 2003
"... We provide an overview of the extensive recent results on the Shannon capacity of single-user and multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity gains have been predicted for such channels, these predictions are based on somewhat unrealistic assumptions about t ..."

An analysis of a large scale habitat monitoring application

by Robert Szewczyk, Alan Mainwaring, Joseph Polastre, John Anderson, David Culler - IN PROCEEDINGS OF THE SECOND ACM CONFERENCE ON EMBEDDED NETWORKED SENSOR SYSTEMS (SENSYS , 2004
"... Habitat and environmental monitoring is a driving application for wireless sensor networks. We present an analysis of data from a second generation sensor networks deployed during the summer and autumn of 2003. During a 4 month deployment, these networks, consisting of 150 devices, produced unique d ..."

able to accurately predict lifetime of the single-hop network, but we underestimated the impact of multihop traffic overhearing and the nuances of power source selection. While initial packet loss data was commensurate with lab experiments, over the duration of the deployment, reliability

Probabilistic Slicing for Predictive Impact Analysis

by Raul Santelices, Mary Jean Harrold
"... Program slicing is a technique that determines which statements in a program affect or are affected by another statement in that program. Static forward slicing, in particular, can be used for impact analysis by identifying all potential effects of changes in software. This information helps develop ..."
Abstract - Cited by 12 (6 self) - Add to MetaCart
an empirical study that shows the effectiveness of p-slicing for predictive impact analysis and we discuss potential benefits for other tasks. 1.

Predictability Impacts of Airport Surface Automation

by Yi Liu, Mark Hansen, Gautam Gupta, Waqar Malik, Yoon Jung
"... Performance analysis for airport surface automation typically focuses on capacity utilization and fuel efficiency. Predictability, while recognized as an important day-of-operation performance goal, has received little attention. One reason could be that applicable predictability metrics have not be ..."

not been developed in the context of airport surface operations management. This study addresses this gap by proposing metrics for predictability performance evaluation. Using these metrics, we assess the predictability impacts of automation on airport surface operations using data from a Spot and Runway

Predicting the impacts of climate change on the distribution of species: are bioclimate envelope models useful?

by Richard G Pearson , Terence P Dawson - Global Ecology and Biogeography , 2003
"... ABSTRACT Modelling strategies for predicting the potential impacts of climate change on the natural distribution of species have often focused on the characterization of a species' bioclimate envelope. A number of recent critiques have questioned the validity of this approach by pointing to th ..."

The Impact of the Potential Duration of Unemployment Benefits on the Duration of Unemployment

by L.F. Katz, Lawrence F. Katz, Bruce D. Meyer, Dale Mortensen, Nick Stern - Journal of Public Economics , 1997
"... This paper uses two data sets to examine the impact of the potential duration of unemployment insurance (UI) benefits on the duration of unemployment and the time pattern of the escape rate from unemployment in the United States. The first part of the empirical work uses a large sample of househ ..."

that policies that extend the potential duration of benefits increase the mean duration of unemployment by substantially more than policies with the same predicted impact on the total UI budget that raise the level of benefits while holding potential duration constant.

Aerodynamic design via control theory

Temporal construal

by Yaacov Trope, Nira Liberman, Dan Gilbert, Tory Higgins, Daniel Kahneman, Arie Kruglanski - Psychological Review , 2003
"... Construal level theory proposes that temporal distance changes people’s responses to future events by changing the way people mentally represent those events. The greater the temporal distance, the more likely are events to be represented in terms of a few abstract features that convey the perceived ..."

the perceived essence of the events (high-level construals) rather than in terms of more concrete and incidental details of the events (low-level construals). The informational and evaluative implications of high-level construals, compared with those of low-level construals, should therefore have more impact
