The well-known similarity measures Jaccard, Salton’s cosine, Dice and several related overlap measures for vectors are compared. While general relations are not possible to prove, we study these measures on the “trajectories” of the form , where is a constant and denotes the Euclidean norm of a vector. In this case, direct functional relations between these measures are proved. For Jaccard we prove that it is a convexly increasing function ...

This article contains a proof of the MDS conjecture for k ? 2p ? 2. That is, that if S is a set of vectors of Fkq in which every subset of S of size k is a basis, where q = p h , p is prime and q is not and k ? 2p ? 2, then |S| ? q + 1. It also contains a short proof of the same fact for k ? p, for all q.

© 2015 IEEE. This paper proposes a novel approach for automatic speaker height estimation based on the i-vector framework. In this method, each utterance is modeled by its corresponding i-vector. Then artificial neural networks (ANNs) and least-squares support vector regression (LSSVR) are employed to estimate the height of a speaker from a given utterance. The proposed method is trained and tested on the telephone speech signals of National ...
