2.1 Previous Attempts at P3P Enforcement
"... The Web provides different ways to communicate and perform activities that vary from simple to sophisticated: using forums on websites, online shopping, orchestrating Web Services. All of them involve processing data about the user, be it technical (e.g., the version of the user’s browser or the IP ..."

The Web provides different ways to communicate and perform activities that vary from simple to sophisticated: using forums on websites, online shopping, orchestrating Web Services. All of them involve processing data about the user, be it technical (e.g., the version of the user’s browser or the IP address) or personal information (name, address, gender, credit card number, etc.). In order to give the user control over their data on the Web, P3P, the Platform for Privacy Preferences, [5] was officially recommended by the World Wide Web Consortium in 2002. P3P is a language and a protocol allowing websites to describe data practices: what data is collected, what for, how long it will be stored and what parts of the data are exposed to other parties. These policies are declarative and non-executable, which leads to the topic of presented work: How to make Web-based systems comply with declared policies? How to make systems policy-aware?

Mixtures of Probabilistic Principal Component Analysers
, 1998
"... Principal component analysis (PCA) is one of the most popular techniques for processing, compressing and visualising data, although its effectiveness is limited by its global linearity. While nonlinear variants of PCA have been proposed, an alternative paradigm is to capture data complexity by a com ..."

combination of local linear PCA projections. However, conventional PCA does not correspond to a probability density, and so there is no unique way to combine PCA models. Previous attempts to formulate mixture models for PCA have therefore to some extent been ad hoc. In this paper, PCA is formulated within a
Gene selection for cancer classification using support vector machines
- Machine Learning
"... Abstract. DNA micro-arrays now permit scientists to screen thousands of genes simultaneously and determine whether those genes are active, hyperactive or silent in normal or cancerous tissue. Because these new micro-array devices generate bewildering amounts of raw data, new analytical methods must ..."

Previous attempts to address this problem select genes with correlation techniques. We propose a new method of gene selection utilizing Support Vector Machine methods
The "Independent Components" of Natural Scenes are Edge Filters
, 1997
"... It has previously been suggested that neurons with line and edge selectivities found in primary visual cortex of cats and monkeys form a sparse, distributed representation of natural scenes, and it has been reasoned that such responses should emerge from an unsupervised learning algorithm that attem ..."

SEAD: Secure Efficient Distance Vector Routing for Mobile Wireless Ad Hoc Networks
, 2003
"... An ad hoc network is a collection of wireless computers (nodes), communicating among themselves over possibly multihop paths, without the help of any infrastructure such as base stations or access points. Although many previous ad hoc network routing protocols have been based in part on distance vec ..."

Adapting to unknown smoothness via wavelet shrinkage
- JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION
, 1995
"... We attempt to recover a function of unknown smoothness from noisy, sampled data. We introduce a procedure, SureShrink, which suppresses noise by thresholding the empirical wavelet coefficients. The thresholding is adaptive: a threshold level is assigned to each dyadic resolution level by the princip ..."

Image Inpainting
, 2000
"... Inpainting, the technique of modifying an image in an undetectable form, is as ancient as art itself. The goals and applications of inpainting are numerous, from the restoration of damaged paintings and photographs to the removal/replacement of selected objects. In this paper, we introduce a novel a ..."

Brain magnetic resonance imaging with contrast dependent on blood oxygenation.

, 1990
"... ABSTRACT Paramagnetic deoxyhemoglobin in venous blood is a naturally occurring contrast agent for magnetic resonance imaging (MRI). By accentuating the effects of this agent through the use of gradient-echo techniques in high fields, we demonstrate in vivo images of brain microvasculature with imag ..."
