It follows from our results that as n → ∞ the average distance between the root and the (nearer) centroid node of a recursive tree Tn tends to 1; and the average value of the label of the (nearer) centroid node tends to 5/2.

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...

The centroid decomposition, an approximation for the singular value decomposition (SVD), has a long history among the statistics/psychometrics community for factor analysis research. We revisit the centroid method in its original context of factor analysis and then adapt it to other than a covariance matrix. The centroid method can be cast as an O(n)-step ascent method on a hypercube. It is sho...

The centroid decomposition, an approximation for the singular value decomposition, had a long history among the statistics/psychometrics community for factor analysis research. We revisit the centroid method first in its original context of factor analysis and then adapt it to other than a covariance matrix. The centroid method can be cast as an O(n)-step ascent method on a hypercube. It is sho...

Interavl type-2 fuzzy numbers (IT2FNs) are used in many real problems such as multiple attribute decision making (MADM) problems, to model the opinions/judgments of experts. This paper, using centroid points and uncertainty degrees of IT2FNs, presents a new method to rank them. Also, we present new methods based on Choquet integral and various types of Power average to aggregate a set of IT2FNs...

Automatic classification of schizophrenia patients and healthy controls based on their 3-D MRI deformation images is introduced here. The image data are reduced by 2DPCA to avoid high computational expenses. Consecutively, reduced data are classified into the two groups according to the centroid method or the average linkage method. The results show that the algorithm gives better results while...
