♣ Let X and Y be two discrete r.v.'s and let R be the corresponding space of X and Y. The joint p.d.f. of X = x and Y = y, denoted by f (x, y) = P (X = x, Y = y), has the following properties: (a) 0 ≤ f (x, y) ≤ 1, f (x, y) ≥ 0 for − ∞ < x, y < ∞. ∞ −∞ ∞ −∞ f (x, y)dxdy = 1. y f (x, y) (∞ −∞ f (x, y)dy), x ∈ R x. ♣ The marginal p.d.f. of Y is defined as f Y (y) = x f (x, y) (∞ −∞ f (x, y)dx), y...

Following the entropy method this paper presents general concentration inequalities, which can be applied to combinatorial optimization and empirical processes. The inequalities give improved concentration results for optimal travelling salesmen tours, Steiner trees and the eigenvalues of random symmetric matrices. 1 Introduction Since its appearance in 1995 Talagrand’s convex distance inequali...

We give the cumulative distribution functions, the expected values, and the moments of weighted lattice polynomials when regarded as real functions of independent random variables. Since weighted lattice polynomial functions include ordinary lattice polynomial functions and, particularly, order statistics, our results encompass the corresponding formulas for these particular functions. We also ...

Ambient assisted living technologies (AAL) are regarded as a promising solution to support aging in place. Yet, their efficacy has to be demonstrated in terms of benefits for independent living and for work conditions of caregivers. Hence, the purpose of this study was to assess the benefits of a multi-task AAL platform for both Frail older Individuals (FIs) and professional caregivers with res...

This paper documents the significant components of a state-ofthe-art language-independent query-by-example spoken term detection system designed for the Query by Example Search on Speech Task (QUESST) in MediaEval 2015. We developed exact and partial matching DTW systems, and WFST based symbolic search systems to handle different types of search queries. To handle the noisy and reverberant spee...

In this paper, we describe the “Query by Example Search on Speech Task” (QUESST, formerly SWS, “Spoken Web Search”), held as part of the MediaEval 2014 evaluation campaign. As in previous years, the proposed task requires performing language-independent audio search in a low resource scenario. This year, the task has been designed to get as close as possible to a practical use case scenario, in...

Let be a sequence of weakly negative dependent (denoted by, WND) random variables with common distribution function F and let be other sequence of positive random variables independent of and for some and for all . In this paper, we study the asymptotic behavior of the tail probabilities of the maximum, weighted sums, randomly weighted sums and randomly indexed weighted sums of heavy...

‎the main purpose of this note is to establish some bounds in poisson approximation for row-wise arrays of independent geometric distributed random variables using the operator method‎. ‎some results related to random sums of independent geometric distributed random variables are also investigated.
