Discovering significant patterns

by Geoffrey I. Webb , 2007
"... Pattern discovery techniques, such as association rule discovery, explore large search spaces of potential patterns to find those that satisfy some user-specified constraints. Due to the large number of patterns considered, they suffer from an extreme risk of type-1 error, that is, of finding patter ..."

Haploview: analysis and visualization of LD and haplotype maps

by J. C. Barrett, B. Fry, J. Maller, M. J. Daly - BIOINFORMATICS , 2005
"... Summary: Research over the last few years has revealed significant haplotype structure in the human genome. The characterization of these patterns, particularly in the con-text of medical genetic association studies, is becoming a routine research activity. Haploview is a software pack-age that prov ..."

, the more significant is the property for that sequence. Results: We present a compression algorithm that tests the presence of a particular type of dosDNA (defined ordered sequence-DNA): approximate tandem repeats of small motifs (i.e. of lengths <4). This algorithm has been experimented with on four

Reality Mining: Sensing Complex Social Systems

by Nathan Eagle, Alex Pentland - J. OF PERSONAL AND UBIQUITOUS COMPUTING , 2005
"... We introduce a system for sensing complex social systems with data collected from one hundred mobile phones over the course of six months. We demonstrate the ability to use standard Bluetooth-enabled mobile telephones to measure information access and use in different contexts, recognize social patt ..."

Automatic Retrieval and Clustering of Similar Words

by Dekang Lin , 1998
"... greatest challenges in natural language learning. We first define a word similarity measure based on the distributional pattern of words. The similarity measure allows us to construct a thesaurus using a parsed corpus. We then present a new evaluation methodology for the automatically constructed th ..."

Do investment-cash flow sensitivities provide useful measures of financing constraints?

by Steven N. Kaplan, Luigi Zingales - QUARTERLY JOURNAL OF ECONOMICS , 1997
"... No. This paper investigates the relationship between financing constraints and investment-cash flow sensitivities by analyzing the firms identified by Fazzari, Hubbard, and Petersen as having unusually high investment-cash flow sensitivities. We find that firms that appear less financially constra ..."

constrained exhibit significantly greater sensitivities than firms that appear more financially constrained. We find this pattern for the entire sample period, subperiods, and individual years. These results (and simple theoretical arguments) suggest that higher sensitivities cannot be interpreted as evidence

DSR: The Dynamic Source Routing Protocol for Multi-Hop Wireless Ad Hoc Networks”, in Ad Hoc Networking, edited by Charles E.

by David B Johnson , David A Maltz , Josh Broch - Perkins, Chapter , 2001
"... Abstract The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and self-configuring, without the need for any existing network ..."

We have evaluated the operation of DSR through detailed simulation on a variety of movement and communication patterns, and through implementation and significant

Beyond Market Baskets: Generalizing Association Rules To Dependence Rules

by Craig Silverstein, SERGEY BRIN , RAJEEV MOTWANI , 1998
"... One of the more well-studied problems in data mining is the search for association rules in market basket data. Association rules are intended to identify patterns of the type: “A customer purchasing item A often also purchases item B. Motivated partly by the goal of generalizing beyond market bask ..."

Range-Free Localization Schemes for Large Scale Sensor Networks

by Tian He, Chengdu Huang, Brain M. Blum, John A. Stankovic, Tarek Abdelzaher , 2003
"... Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute point-to-point distance estimates. Because coarse accura ..."

We compare our work via extensive simulation, with three state-of-the-art range-free localization schemes to identify the preferable system configurations of each. In addition

The embryonic cell lineage of the nematode Caenorhabditis elegans

by J. E. Sulston, H. R. Horvitz - Dev. Biol , 1983
"... The number of nongonadal nuclei in the free-living soil nematode Caenorhabditis elegans increases from about 550 in the newly hatched larva to about 810 in the mature hermaphrodite and to about 970 in the mature male. The pattern of cell divisions which leads to this increase is essentially invarian ..."
