K-RANK: AN EVOLUTION OF Y-RANK FOR MULTIPLE SOLUTIONS PROBLEM

Freud, Rank and, the problem of anxiety

Anxiety has always been a phenomenon of great importance among psychoanalysts. Freud, as the founder of psychoanalysis, took much notice of this phenomenon from the beginning of his career, and he was always trying to give a comprehensive explanation for this problem. Therefore, throughout his career, he modified his theories about anxiety frequently, and even one time, he changed his whole the...

A Matrix Rank Problem

Compound Rank-k Projections for Bilinear Analysis

In many real-world applications, data are represented by matrices or high-order tensors. Despite the promising performance, the existing 2-D discriminant analysis algorithms employ a single projection model to exploit the discriminant information for projection, making the model less flexible. In this paper, we propose a novel compound rank- k projection (CRP) algorithm for bilinear analysis. T...

Higher rank Einstein solvmanifolds

In this paper we study the structure of standard Einstein solvmanifolds of arbitrary rank. Also the validity of a variational method for finding standard Einstein solvmanifolds is proved.

An efficient approach for the rank aggregation problem

This paper presents some computational properties of the Rank-Distance, a measure of similarity between partial rankings. We show how this distance generalizes the Spearman footrule distance, preserving its good computational complexity: the Rank-Distance between two partial rankings can be computed in linear time, and the rank aggregation problem can be solved in polynomial time. Further, we p...
