Diversity or complementarity of experts in ensemble pattern recognition and information processing systems is widely-observed by researchers to be crucial for achieving performance improvement upon fusion. Understanding this link between ensemble diversity and fusion performance is thus an important research question. However, prior works have theoretically characterized ensemble diversity and ...

Diverse boards have been seen as providing impetus for initiating change. However, diversity may introduce conflict and impede decision-making, which could hinder the ability of the firm to make strategic change, especially in times when firm performance is low. Integrating threat-rigidity theory and team diversity research, we examine how board gender diversity, firm performance, and the power...

Performance of space diversity techniques is considered for transmissions in mobile radio environments. Optimal performances are derived for any multipath Rayleigh fading channel for Nth-order diversity whenever the signals delivered by the antennas are correlated or not. The proposed theoretical study, illustrated for 2PSK, is suitable for any other modulation schemes (constellation, symbol ra...

This paper brings together three streams of research concerning diversity-related performance of groups: team diversity research, complexity science, and the social network perspective. Empirical research in team diversity produces contradictory results about the effects of cognitive diversity on team performance in terms of information processing capabilities. This is why we propose to complem...

Morphological diversity is routinely used to infer ecological variation among species because differences in form underlie variation in functional performance of ecological tasks like capturing prey, avoiding predators, or defending territories. However, many functions have complex morphological bases that can weaken associations between morphological and functional diversification. We investig...

In this paper, we consider how the structures of tasks and teams interact to affect team performance. We study the effects of diversity in experience on a team's ability to respond to task changes by separately examining interpersonal team diversity (i.e., differences in experience across the entire team) and intrapersonal team diversity (i.e., whether individuals on the team are more or less s...

Similar to direct sequence code division multiple access (DS-CDMA), site diversity can be applied to a multicarrier-CDMA (MCCDMA) cellular system to improve the bit error rate (BER) performance for a user with weak received signal power, thus resulting in an increased link capacity. In this paper, the downlink site diversity reception using frequency-domain equalization based on minimum mean sq...

Clustering ensemble performance is affected by two main factors: diversity and quality. Selection of a subset of available ensemble members based on diversity and quality often leads to a more accurate ensemble solution. However, there is not a certain relationship between diversity and quality in selection of subset of ensemble members. This paper proposes the Hierarchical Cluster Ensemble Sel...
