Linear correlation
"... Digital nature denotes that digital data can be changed, manipulated, and even ownership right of such data can be misused. The watermarking schemes have been introduced to prevent unauthorized users from abusing digital information, and to uphold ownership rights of digital contents which have usag ..."

This study aims to test blind linear correlation technique for image watermarking by Stirmark benchmark version four which includes sixteen diverse tests, such as distortions, and attacks that are wellknown for image processing. Those tests are applied on the image

Crosscommodity price dependence This presentation introduces the notion of price dependence in the general framework of copula functions. The problem of pricing energy spread claims, such as the spark spread option, is tackled using the alternative approaches represented by the BenthKettler copulabased model and a multidimensional extension of the Threshold spikediusion model proposed by Roncoroni (2002). This extension has been pursued in collaboration with Rachid Id Brik at ESSEC Business School. * These notes can be freely distributed in paper version only and under the sole requirement that the author's name and indicated references are explicitly mentioned.

Linear Correlation Estimation

However, observed financial data are rarely normally distributed and tend to have marginal distributions with heavier tails. Furtherm ..."

Using Linear Algebra for Intelligent Information Retrieval
 SIAM REVIEW
, 1995
"... Currently, most approaches to retrieving textual materials from scientific databases depend on a lexical match between words in users' requests and those in or assigned to documents in a database. Because of the tremendous diversity in the words people use to describe the same document, lexical ..."

Currently, most approaches to retrieving textual materials from scientific databases depend on a lexical match between words in users' requests and those in or assigned to documents in a database. Because of the tremendous diversity in the words people use to describe the same document, lexical methods are necessarily incomplete and imprecise. Using the singular value decomposition (SVD), one can take advantage of the implicit higherorder structure in the association of terms with documents by determining the SVD of large sparse term by document matrices. Terms and documents represented by 200300 of the largest singular vectors are then matched against user queries. We call this retrieval method Latent Semantic Indexing (LSI) because the subspace represents important associative relationships between terms and documents that are not evident in individual documents. LSI is a completely automatic yet intelligent indexing method, widely applicable, and a promising way to improve users...
Dynamic conditional correlation: A simple class of multivariate generalized autoregressive conditional heteroskedasticity models
 Journal of Business and Economic Statistics

"... Time varying correlations are often estimated with Multivariate Garch models that are linear in squares and cross products of the data. A new class of multivariate models called dynamic conditional correlation (DCC) models is proposed. These have the flexibility of univariate GARCH models coupled wi ..."

Eigenfaces vs. Fisherfaces: Recognition Using Class Specific Linear Projection

"... We develop a face recognition algorithm which is insensitive to gross variation in lighting direction and facial expression. Taking a pattern classification approach, we consider each pixel in an image as a coordinate in a highdimensional space. We take advantage of the observation that the images ..."

An approach to correlate tandem mass spectral data of peptides with amino acid sequences in a protein database

The size elfect is not linear in the market value; the main effect occurs for very small tirms while there is little difference m return between average sized and large firms. It IS not known whether size per se is responsible for the effect or whether size
