Higher-order Nonnegative CANDECOMP/PARAFAC Tensor Decomposition Using Proximal Algorithm
2019
Tensor decomposition is a powerful tool for analyzing multiway data. Nowadays, with the fast development of multisensor technology, more and more data appear in higherorder (order > 4) and nonnegative form. However, the decomposition of higher-order nonnegative tensor suffers from poor convergence and low speed. In this study, we propose a new nonnegative CANDECOM/PARAFAC (NCP) model using proximal algorithm. The block principal pivoting method in alternating nonnegative least squares (ANLS) framework is employed to minimize the objective function. Our method can guarantee the convergence and accelerate the computation. The results of experiments on both synthetic and real data demonstrate …
Contents and functions of dramatizations in team decision making
2017
This study examines the contents and functions of dramatizations in natural team decision making. Theoretically, the study employs symbolic convergence theory to understand decision making as a complex phenomenon constructed in symbolic communication. Observational meeting data and thematic interview data from an autonomous team in Finland were analyzed. A fantasy theme analysis and an inductive, rhetorical discourse analysis revealed three rhetorical visions and seven functions of dramatizations in the team’s decision making. Visions represented social, righteous, and pragmatic master analogues. The functions of dramatizations were legitimizing independent and current decisions, reinforci…
The Aqua-Planet Experiment (APE): CONTROL SST Simulation
2013
Climate simulations by 16 atmospheric general circulation models (AGCMs) are compared on an aqua-planet, a water-covered Earth with prescribed sea surface temperature varying only in latitude. The idealised configuration is designed to expose differences in the circulation simulated by different models. Basic features of the aqua-planet climate are characterised by comparison with Earth. The models display a wide range of behaviour. The balanced component of the tropospheric mean flow, and mid-latitude eddy covariances subject to budget constraints, vary relatively little among the models. In contrast, differences in damping in the dynamical core strongly influence transient eddy amplitudes…
Fiksācijas disparitāte un konverģences nepietiekamība.
2020
Maģistra darbs ir uzrakstīts angļu valodā uz 47 lapām, tas satur 19 attēlus, 14 tabulas un 51 atsauci uz literatūras avotiem. Mērķis bija novērtēt fiksācijas disparitātes saistību ar konverģences nepietiekamību. Pētījumam bija divas daļas: 1. grupā bija 5 dalībnieki ar konverģences nepietiekamību, kas veica 12 nedēļu ilgu redzes terapiju, lai izvērtētu tās ietekmi uz binokulārajām funkcijām, lasīšanas ātrumu, CISS vērtējumu un fiksācijas disparitāti; 2. grupā bija 51 dalībnieks, kuri aizpildīja CISS aptauju un veica fiksācijas disparitātes mērījumus, lai izvērtētu šo divu parametru saistību. Redzes treniņi būtiski uzlaboju konverģence tuvuma punktu un pozitīvās fūzijas rezerves, kā arī sama…
Fonds structurels, effets de débordement géographique et croissance régionale en Europe.
2008
Les fonds structurels constituent l’un des instruments financiers de la politique regionale europeenne les plus intensement utilises afin de promouvoir la convergence entre les regions des pays membres de l’Union europeenne. Cependant, de nombreuses divergences theoriques et empiriques existent dans la litterature quant a leur capacite a encourager la croissance economique des regions les plus defavorisees. Par consequent, cet article se propose de proceder a des estimations complementaires en integrant des elements nouveaux : tout d’abord, nous adoptons une approche par l’econometrie spatiale afin de prendre en compte de possibles effets de debordement geographique entre regions ; ensuite,…
