Linear models and empirical bayes methods for assessing differential expression in microarray experiments.

by Gordon K Smyth , Gordon K Smyth - Stat. Appl. Genet. Mol. Biol. , 2004
"... Abstract The problem of identifying differentially expressed genes in designed microarray experiments is considered. Lonnstedt and Speed (2002) derived an expression for the posterior odds of differential expression in a replicated two-color experiment using a simple hierarchical parametric model. ..."

. The purpose of this paper is to develop the hierarchical model of Lonnstedt and Speed (2002) into a practical approach for general microarray experiments with arbitrary numbers of treatments and RNA samples. The model is reset in the context of general linear models with arbitrary coefficients and contrasts

Robust face recognition via sparse representation

by John Wright, Allen Y. Yang, Arvind Ganesh, S. Shankar Sastry, Yi Ma - IEEE TRANS. PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 2008
"... We consider the problem of automatically recognizing human faces from frontal views with varying expression and illumination, as well as occlusion and disguise. We cast the recognition problem as one of classifying among multiple linear regression models, and argue that new theory from sparse signa ..."

signal representation offers the key to addressing this problem. Based on a sparse representation computed by ℓ 1-minimization, we propose a general classification algorithm for (image-based) object recognition. This new framework provides new insights into two crucial issues in face recognition: feature

Ecology of the family as a context for human development: Research perspectives.

by Urie Bronfenbrenner , Josephine Arastah , Mavis Hetherington , Richard Lerner , Jeylan T Mortimer , Joseph H Pleck , Lea Pulkinnen , Michael Rutter , Klaus Schneewind , Diana Slaughter - Developmental Psychology, , 1986
"... This review collates and examines critically a theoretically convergent but widely dispersed body of research on the influence of external environments on the functioning of families as contexts of human development. Investigations falling within this expanding domain include studies of the interac ..."

; and public policies affecting families and children. A second major focus is on the patterning of environmental events and transitions over the life course as these affect and are affected by intrafamilial processes. Special emphasis is given to critical research gaps in knowledge and priorities for future

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 ..."

significant for smaller firms. CENTRALTO THE ANALYSIS of market microstructure is the notion that in a market with asymmetrically informed agents, trades convey information and therefore cause a persistent impact on the security price. The magnitude of the price effect for a given trade size is generally held

Open Mind Common Sense: Knowledge acquisition from the general public

by Push Singh, Thomas Lin, Erik T. Mueller, Grace Lim, Travell Perkins, Wan Li Zhu , 2002
"... Abstract. Open Mind Common Sense is a knowledge acquisition system designed to acquire commonsense knowledge from the general public over the web. We describe and evaluate our first fielded system, which enabled the construction of a 450,000 assertion commonsense knowledge base. We then discuss how ..."

Explaining Cryptosystems to the General Public

by Tim Bell, Harold Thimbleby, Mike Fellows, Ian Witten, Neil Koblitz, Key Words
"... : Modern cryptography can achieve levels of security and authentication that non-specialists find literally incredible. Techniques include informationhiding protocols, zero-knowledge proofs and public key cryptosystems; they can be used to support applications like digital signatures, digital cas ..."

On the Rationality of the General Public

by Gebhard Kirchgässner, Jörg Baumberger , 2005
"... Using Allensbach survey data about how people look forward to the coming year, we construct true ex post-forecasts and compare them with the forecasts produced by the German Council of Economic Experts and by the Economic Research Institutes. Then, we perform rationality tests for these forecast ser ..."
Abstract - Add to MetaCart
the professional forecasts do not. Thus, when making expectations, the German general public seems to consider more information than the professional forecasters.

On The Limits of Steganography

by Ross Anderson, Fabien Petitcolas - IEEE Journal of Selected Areas in Communications , 1998
"... In this paper, we clarify what steganography is and what it can do. We contrast it with the related disciplines of cryptography and tra#c security, present a unified terminology agreed at the first international workshop on the subject, and outline a number of approaches---many of them developed to ..."
