Abstract—This paper presents a novel approach to building a WLAN-based location fingerprinting system. Our algorithm intelligently transforms received signal strength (RSS) into principal components (PCs) such that the information of all access points (APs) is more efficiently utilized. Instead of selecting APs, the proposed technique replaces the elements with a subset of PCs to simultaneously improve the accuracy and reduce the online computation. Our experiments are conducted in a realistic WLAN environment. The results show that the mean ....etc

Face Recognition using the Techniques Base on Principal Component Analysis (PCA)

several past few years, Face Recognition has become more significant. Although, other identification methods such as Fingerprints or Iris recognition are currently in use, face recognition has its own application.

Principal Component Analysis (PCA) has been variously used in pattern recognition applications, especially in face recognition field. In this seminars, several techniques based on standard PCA, Fisher Linear ....etc

Principal Component Analysis



Introduced by Pearson (1901) and Hotelling (1933) to describe the variation in a set of multivariate data in terms of a set of uncorrelated variables

We typically have a data matrix of n observations on p correlated variables x1,x2,…xp

PCA looks for a transformation of the xi into p new variables yi that are uncorrelated


Transformation



What is a reasonable choice for the  ?
Remember: We wanted a transform ....etc

Abstract Breadth-first and depth-first search are basic search strategies upon which many other search algorithms are built. In this paper, we describe an approach to integrating these two strategies in a single algorithm that combi ....etc

Abstract

Interspecies allometric scaling, based on the assumption that a change in pharmacokinetic parameters correlates closely with body weight, can be described as an operation when a pharmacokinetic parameter of interest is scaled across species. This method has become a useful instrument in drug development, especially at the preclinical discovery stage, because the extrapolation facilitates the process of dosing transitions from animals to man and accelerates the drug testing and approval process. For greater extrapolation accur ....etc
